I just had a dispute with a friend, he tells me that the best anti-virus utility that works without installation on a computer is . I don’t argue, and you often mention it in your articles, it actually finds and neutralizes malware well, but I think Kaspersky utilities are no worse than Dr.Web utilities.

Free kaspersky utilities

In this article, we will download and apply in combat conditions free utilities Kaspersky- Kaspersky Virus Removal Tool, Kaspersky Security Scan, and TDSSKiller anti-rootkit utility. Let's get acquainted with the rescue disk Kaspersky Rescue Disk. How everything works for Kaspersky (and it works), you will see for yourself and draw a conclusion.

Undoubtedly, it is worth carrying Kaspersky anti-virus utilities on a USB flash drive and using them as needed in the fight against viruses. I did not write anything about these utilities just because there is simply not enough time.

All Kaspersky Lab products are based on the latest developments in the field of anti-virus technologies, including new "cloud" technologies. Take, for example, Kaspersky Virus Removal Tool (AVPTool) - a constantly updated free virus scanner. It should be used from time to time by scanning your computer for the presence malware. By scanning your computer, this utility neutralizes malicious programs on your computer: Trojans, Internet worms, rootkits, as well as spyware and adware. Kaspersky Virus Removal Tool can be run in automatic and manual modes.
  • But it is important to know that this utility does not provide real-time protection for your computer, that is, Kaspersky Virus Removal Tool will not replace your standard antivirus, but will only help it. While working on your computer, Kaspersky utilities do not conflict with your anti-virus software.
  • A very important note. You must know everything about all the utilities you use, so that the situation described in the second letter does not happen. The Kaspersky Security Scan utility does not actually remove viruses, but you still need to use it and now you will see how. We will check the free utilities of Kaspersky for performance on the computer of my friend, when visiting one site that turned out to be malicious, he planted two Trojans for himself - in the Startup folder and the Temp temporary files folder.
All free utilities from Kaspersky can be downloaded on the official page http://www.kaspersky.com/virusscanner

Kaspersky Virus Removal Tool

Let's start with the Kaspersky Virus Removal Tool utility, analyze all its settings and check our computer for viruses.

Russian language and click Download, then download the program installer to our computer and run it.

We agree with the license agreement and click Get to work.

The free Kaspersky Virus Removal Tool can be run in the Automatic check, there is also a manual treatment mode.

Before pressing Run check, I advise you to go to the program settings. In option Check area, be sure to check My Documents, My Mail and most important Disk (C:). Why?

When scanning an infected computer, I did not check Disk (C:) in the settings and the Kaspersky Virus Removal Tool found only one virus that is in startup,
, but did not find the second malware - located in the Temp temporary files folder
. I had to rescan Disk (C:) separately, and only during rescanning the virus was found.
Security level can be left in the middle

Option Action, you can check the item - Prompt when found.

If the Kaspersky Virus Removal Tool finds you have a virus program, it will inform you to Disinfect , (if possible) Remove (recommended) or Ignore .

So let's go, let's go Run check

First Trojan was found in 8 minutes.

The second Trojan, as I said, was found during a rescan, so do not forget to mark the drive (C:) for checking in the program settings. The utility immediately offered to remove the second malicious program.

As for manual treatment. It takes place in three stages. Click Collection of information about the system,

the utility collects the information it needs, which is located in the avptool_sysinfo.zip file

Next, register on the Kaspersky Lab forum in the Fighting viruses branch, ask your question and attach the avptool_sysinfo.zip archive, you should definitely get an answer, and sometimes experts may suggest that you execute a script that you need to copy into the Script execution window and click Run script.

At the end of the utility, such a proposal arrives. If you press the button Set protection, we will immediately get to the page with paid antivirus solutions Kaspersky Labs.


Free utility Kaspersky Security Scan

Let's move on to the second Kaspersky Security Scan utility, we will scan the same infected computer with two viruses: in Startup and in the Temp temporary files folder.

The Kaspersky Security Scan utility does not remove viruses, but after scanning your computer, it provides detailed information about threats in your operating system and where they were found, vulnerabilities, and other problems. It all looks like this.
Let's go back to the page http://www.kaspersky.com/virusscanner, select Kaspersky Security Scan and click Download.

Download and run the utility. Again, I want to say that if Quick check does not satisfy you, then choose Full check. In my case, the situation with the Quick Scan was repeated, it found only one virus in Startup.

C:\Users\Username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
During a full scan, the utility found a second malware in temporary files
C:\Users\Username\AppData\Local\Temp

If the utility finds malware will give you their location.

Vulnerabilities

Other problems . Gives out very important information about vulnerabilities related to the settings of programs installed on your computer and the operating system itself. As you can see, the utility correctly noted problems on my computer related to autorun from various media that need to be fixed.


Kaspersky Rescue Disk

The advantage of checking the operating system with boot disk Salvation before other utilities is that the malicious programs that are in the operating system are in a non-working state, you can say - they just lie on the hard drive.

Select Kaspersky Rescue Disk and click download.

Download the disk image in ISO format, burn it to a disc. Who does not know how to burn iso image on blank disc CD or DVD, read our article
So, after we have burned the image to a blank CD, we boot our computer from the Kaspersky Rescue Disk. Again, who does not know how, read our article
In this window, to continue downloading, you need to press any key on the keyboard.

We choose the language Russian, however, who needs what.

We accept the conditions - press the key 1.

Choose Graphic mode.

Wait for the disks to be mounted.

Before us is the desktop of the anti-virus disk Kaspersky Rescue Disk. Let's take a look at the main features of the disk.
Clicking on Kaspersky Rescue Disk opens the settings window, there is nothing difficult to manage here. We also mark the C: drive for checking for viruses in the settings, or if you want all drives, but the check in this case will take a very long time. Click on the button Run a check objects .

Kaspersky Rescue Disk has a registry editor, which you will agree is very convenient, by the way, it was not available in earlier versions of the disk.

You can also use the File Manager if you need to move your files from one partition hard drive another.

And with the help of the built-in browser, you can access the Internet.


TDSSKiller - protection against rootkits

Well, the turn has come to the TDSSKiller utility, which can help you detect and neutralize rootkits on your computer. A rootkit is a program for hiding the presence of a malicious program in the operating system, which helps a hacker to manage a hacked Windows and hide traces of his malicious activity by hiding destructive processes and the rootkit itself.

You can download it on the official website of the Kaspersky Lab, by the way, this link is available detailed instructions using the utility http://support.kaspersky.ru/5353?el=88446 Click Download TDSSKiller.exe

Download and run.

If the program displays a window about the availability for downloading an update, click on Download update.

By default, the utility is configured optimally and nothing needs to be changed. Click Start Check.

If the program after scanning displays such a window - Suspicious object, medium danger - Service: sptd, then this is not a problem. Service: sptd is a service of the program - floppy drive emulator Daemon Tools. You may ask - And how to determine whether it is scary or not?

TDSSKiller can identify the following suspicious services or files:
Hidden service - a hidden key in the registry;
Service blocked– inaccessible key in the registry;
Hidden file - hidden file on disk is hidden when listed in the standard way;
Locked file- the file on the disk is not available for opening in the standard way;
Changed file- when reading, fake file contents are displayed;
Rootkit.Win32.BackBoot.gen - suspected infected boot record MBR.

For a detailed analysis, Kaspersky Lab recommends copying detected objects to quarantine by selecting the Copy to Quarantine action (the file will not be deleted!!!), then send the files to Kaspersky Virus Lab or to be scanned by VirusTotal.com.

The location of the quarantine is the root of the drive C:\TDSSKiller_Quarantine
Open the site VirusTotal.com, then click Select file

Open and Check

Analysis of the sptd.sys file by VirusTotal.com revealed that only one antivirus company, TrendMicro, classified the sptd.sys file as a PAK_Generic.009 virus.

At one time, I determined that this file is safe, but for complete certainty, our reader can send it to the Kaspersky Virus Lab.

The Virus Removal Tool is one of the most effective tools for detecting and removing almost any virus program. Its main advantage is that it does not require installation on a computer. It is enough to download and run it, and then it will do everything itself.

Pros and Cons of Virus Removal Tool

This utility has a lot of advantages, including:

  1. The program is distributed on the Internet for free.
  2. The utility has a nice design and is very easy to use. With its help, even the initial PC user will be able to conduct a complete system scan.
  3. The Virus Removal Tool does not conflict with those installed on the computer, so you can leave them on during the scan.
  4. The utility uses signature and heuristic analysis in its work, which allows you to detect new and unknown viruses.
  5. The program can disinfect infected files.
  6. If the infected computer cannot start in normal mode, this utility can be run in safe mode.
  7. After the program collects all the necessary information about the installed OS, it will create scripts that can be used to carry out manual disinfection.

But in addition to a wide list of advantages, like any program, Virus Removal Tool has a number of disadvantages:

  1. The program works online, protecting the system, and scans and cures only on demand. After a single use of the program, it is uninstalled.
  2. The utility does not know how to update databases, therefore, before a new check, the old database must be deleted and a new one loaded.
  3. Because the utility is free, there is no additional service in it. For example, a user will not be able to ask a question to Kaspersky Lab if he suddenly encounters some difficulties. Questions can only be answered by other users on the Kaspersky forums.

Performing a system check

The Virus Removal Tool can be downloaded from the official website at the link below. After downloading and unpacking the archive, you must agree to the license agreement and click the "Get Started" button. Now the antivirus utility is ready to go.

The program has already set the recommended parameters for the first system check. To start the scan, you just need to click "Start Scan". The utility will check all critical areas, and then you can scan HDD. To do this, click on the gear icon, and in the "Scan area" column, check all the boxes. If your computer has a large amount of data, the scan may take quite a long time. In order not to follow the long process, in the "Actions" menu, you can check the boxes "Treatment" and "Delete if treatment is not possible".

It should be noted that if unlicensed software is installed on the computer, the program can recognize them as a threat to the system, so it is recommended not to check the "Delete" box if there is unlicensed software on the PC. When all settings are set, you can go to the "Automatic Check" section and start the process. Upon completion of the check, it will be possible to view the monitoring results from the "Reports" section.

Unfortunately, not every user has computer device there is an antivirus. Someone is lazy, and someone simply does not consider it a necessity. If suddenly the equipment starts to slow down or ad blocks appear in the browser, you can check your computer for viruses online. To date, there are several services that allow you to quickly scan your PC at any convenient time. Consider best antiviruses and their features.

In fact, without downloading the installer, it is impossible to check the device. The scan goes to online mode, but the checking program itself needs access to your files. So one part of the antivirus functions as a browser module, and the second - in the form of a small application. Let's also get acquainted with a couple of "helpers" that support online verification without downloading.

There are cases when everything was scanned, but nothing dangerous was found, and the device still does not work correctly (there are ad blocks on sites, it is impossible to open the page, etc.), most likely, you need to remove malware from the device. Before you check your computer for viruses for free online, you need to know some features:

  • you will have to download an application that is not a full-fledged program, but has a special directory or connection to the cloud storage where it is located. Another method is to drop the suspicious object for verification directly on the site;
  • such downloadable programs most often do not interfere with installed full-fledged antiviruses;
  • you should use only proven methods of analysis, that is, take utilities directly from manufacturers. If there is third-party advertising on the site, the resource is unsafe. Antivirus developers do not earn money from advertising, they simply sell their products, so they will not place other people's blocks on their own sites.

If everything is clear, you can begin the process.

Perhaps, almost all users know this product. It allows you to effectively check the necessary materials for viruses. Its convenient service quickly analyzes specific objects. For this you need:

  • on the official resource select the item "Overview";
  • specify the path to the file that needs to be scanned;
  • click on the button "Check!" (or Scan).


It works online efficiently and quickly, you do not need to spend a lot of time.

The tool owned by Google Corporation, it helps to check various objects from a PC, as well as various resources on the Internet for the presence of worms, Trojans and other infected software. It is located on the official website, you only need to select the file that needs to be scanned. You can also specify there a link to a page that is suspicious (there is a link below "Check URL"). Click "Check".


After a while, a report will be sent. This is exactly the case when you check for free and without installation additional programs.

Easily scan your home computer for viruses online with ESET Online Scanner

This online scanner also does not need to be downloaded to a computer. It will be uploaded as software module, which functions without an antivirus installer and uses the virus databases of the full-fledged ESET NOD32.


As stated on the site, it can easily detect all types of threats by latest versions bases, as well as perform a heuristic analysis of the content. After activating the product, you can adjust the necessary settings, enable or disable the search unnecessary applications on a PC, scanning archives and other functions.

  • full system scan (takes about forty minutes, it all depends on the speed of the Internet and disk space);
  • detect any type of threat;
  • can find malware even in the registry;
  • makes heuristic analysis;
  • generates a detailed report.


Another advantage is that the online product is automatically destroyed after the verification procedure is completed, so it does not leave any files behind.

At first, Panda had public access a tool that runs immediately in the browser. Currently, there is only a utility that downloads its modules to the computer (no need to be confused, it is not installed and does not affect other antiviruses). The principle of operation is similar to the previous product: anti-virus databases are loaded, and testing of equipment for threats noted in these databases begins. Upon completion, a report on the "finds" will be compiled (when you click on the arrow, the entire detailed information about specific elements and the possibility of deleting them).

It is worth remembering that the items that are in the Unkonown Files and System Cleaning subsections do not always refer to viruses on a PC. The first item is used to store unknown files and strange registry entries for the program. The next will be the possibility of clearing disk space from extra objects. Experts recommend using portable version because it doesn't need to be installed. Among the minuses of this tool, one can single out only the lack of Russian-language support.


Advantages:

  • operational check (about half an hour);
  • identify common threats;
  • highly efficient online cleaning.

Panda is also able to "self-destruct" after it checks and cures files. So it will automatically be deleted, leaving nothing behind.

Another service that allows you to perform a web scan for the presence of malware, trojans. Many users are already familiar with Trend Micro products. Utility available on the developer's site.

After launch, the download of various special files is activated, then you need to accept the terms of the English license and click on the Scan Now button to start system testing. By clicking on the Settings link, below this button, you can select specific objects for scanning, as well as mark whether an accelerated analysis or a full scan is required.


The program does not leave anything behind in the system. It also draws databases from the Cloud, which helps to ensure high level reliability of the utility. In addition, HouseCall allows you to remove detected viruses from your PC. Among the main advantages are:

  • quick analysis - about fifteen minutes;
  • high-quality disposal of viruses, spyware;
  • functions even if an antivirus is already installed on the computer.


Before starting, you should deactivate "heavy" applications on your computer. This way you can speed up testing.

Microsoft Safety Scanner

Microsoft has created its service for one-time check - Microsoft Safety Scanner. The product is valid for ten days, after which you will have to download a fresh one, with corrected and supplemented databases.


There is also a newer tool called . Both services work and do a good job with their functions.

It is one of the most popular and powerful online virus scanners. Kaspersky quickly and highly efficiently checks your hardware, very common in Russia. The program runs in the cloud, so it's easy to check in real time. Main advantages:

  • does not affect speed Windows work(as opposed to a full-fledged product, which consumes a decent amount of resources during the verification process);
  • without conflicts with other antiviruses that are on the PC;
  • does not eliminate the found threats, but simply notifies them (for some, this is a plus, while for others it is inconvenient to remove them manually);
  • presents a report with all the details.


Checking is simple:

  • download setup file;
  • run the program;
  • waiting for the completion of the procedure;
  • remove viruses (if any).

As you can see, you can independently, without downloading software, check your computer for viruses online. The developers have taken care of the users, so that everyone can choose something convenient and suitable for themselves. What product do you use?

Not all people resort to using antivirus on their PC or laptop. Automatic computer scanning consumes quite a lot of system resources and often interferes with comfortable work. And if suddenly the computer starts behaving suspiciously, then you can analyze it for problems online. Fortunately, there are enough services for such a check today.

Below we will consider 5 options for analyzing the system. True, it will not work to carry out this operation without loading a small auxiliary program. Scanning is carried out online, but antiviruses need access to files, and it is rather difficult to do this through a browser window.

Services that allow checking can be divided into two types - these are system and file scanners. The former check the computer completely, the latter are able to analyze only one file uploaded to the site by the user. From simple anti-virus applications, online services differ in the size of the installation package, and do not have the ability to "cure" or remove infected objects.

The main advantage of this service is a thorough scan, which can take about two hours or more, depending on the number of files on your computer. The online scanner is completely deleted after the end of the work and does not leave behind any files.


ESET Scanner will update its databases and start analyzing the PC, after which the program will return the results.

Method 5: VirusTotal

VirusTotal is a service from Google that can check links and files uploaded to it. This method is suitable for cases when, for example, you have downloaded a program and want to make sure that it does not contain viruses. The service can simultaneously analyze a file in 64th (on this moment) databases of other anti-virus tools.

  1. To check the file through this service, select it for download by clicking on the button of the same name.
