Often, users find programs on their computers that they did not install. At this moment, conflicting feelings arise, because everyone knows how many spyware applications and other malicious software are on the Internet. Today's article is addressed to those who have foundBonjour, what is this program,why it is needed and whether it can be removed, we will try to answer these and other questions related to the application.
Bonjour: what is this program?
Bonjour is a development of the American giant Apple and is a network standard that includes a system search service local web servers. They often signal that the program is a malicious product and offer to remove it. This is due to the fact that it regularly transmits and receives data from the network without the participation of the user in this process. In fact, the software background caches data from services and devices that support the Zeroconf protocol and displays them when requested.
Why was Bonjour created? Apple TV is becoming increasingly popular, but to ensure its operation, it requires not only an Internet connection, but also paired devices. To speed up the search for such devices, Bonjour is used; it processes the request and retrieves from cached data those devices that sent similar requests. Thanks to this, you can quickly find the services you need and save time.
Bonjour is used to quickly detect paired devices on a local network. What is it for:
- creating connections with printers and other devices that use Bonjour alerts;
- search for pages on the Internet that meet specified parameters;
- quick search for media libraries for the AirPort Express service;
- give a chance Adobe program Creative Suite quickly establish contact with the required service digital asset management.
The question remains how the program gets onto the computer. It often occurs among vigilant users who carefully monitor the installation of software and do not allow the installation of imposed programs. As a rule, Bonjour gets to the computer regardless of the owner’s wishes; everything happens in the background, just like the software works.
If you recently installed iCloud or Safari for Windows on your computer (despite the fact that it is no longer supported by developers, the browser is still available for download), then you can safely search the list of Bonjour programs. In addition, they can download and install the software themselves Internet Explorer, Adobe Creative Suite, Photoshop CS3, Apple TV Services.
Now we know how it gets to PCBonjour, what is this program?and why it is needed. Alert users can take comfort in knowing that this is not malware, but just ancillary software that provides faster and more stable operation.
Many people will ask: is it possible to remove the component? Yes, of course, if you don't use any of the programs listed above, you won't even notice the absence of Bonjour. Problems may only arise if your printer uses AirPort or has one of the listed programs. iTunes may issue alerts that Bonjour is needed, but overall the functionality of the program will not change. The user will still be able to synchronize and work in the iPhone settings.
Let's figure out how to remove the software. However, it should be taken into account that, if necessary, each of the programs that require auxiliary software during updating can install it again without the user’s knowledge. 
To remove a program, just use the standard method through the control panel.
- Open Programs and Features.
- Find the program you need to remove (it is worth noting that the algorithm is universal and is suitable for removing any unnecessary application).
- Select the line with the necessary software and click the “Delete” command in the table header.
After this, the installation wizard will automatically remove the application. In the future, it is recommended to clean the registry with using CCleaner or any other similar utility.
How to install Bonjour
It happens that after removal, the need for a auxiliary application becomes clear. In this case, the user faces one minor problem - the component is installed together with another product and is not distributed separately. What to do in such a situation? The issue can be completely resolved, and quite simply. 
- Option one. Uninstall one of the programs on your computer that uses the component, such as iTunes or iCloud, and install it again. Along with them, the necessary software will automatically appear.
- Second option. Simply download the installer for one of the programs described above and extract the program from there to install Bonjour. This is not difficult to do. Simply unpack the general installation distribution and find Bonjour.msi in it. This will be the required set for installing only the auxiliary application. Start the process and wait for it to complete.
Now we know Bonjour, what kind of programs are these?and how it ends up on a computer with the Windows operating system. We also found that vigilant users do not have to fear or worry that this will harm their device. Bonjour is a development from a reputable company designed to help devices interact within a local network. Removing the component is not necessary since it does not load the processor and does not interfere with work processes, but if you really want to, you can remove the software without much difficulty or noticeable consequences.
If you have never encountered software from Apple, then you are clearly not familiar with the Bonjour program. But those who have at least once installed QuickTime or iTunes on their computer (with the Windows 7, 8, 10 operating system) may have noticed that Bonjour also appears in the list of installed software. Let's take a closer look at what kind of program this Bonjour is and why you need it (or don't need it at all).
Bonjour is...
First of all, it is intended for a local network. With Bonjour you can discover other computers network devices(printers and other office equipment), etc. In general, from these two sentences we can immediately conclude that the Bonjour program is intended, to a greater extent, for offices or companies whose activities are closely related to the use of computers.
After installing Bonjour on my PC, I didn't get much value out of it. Although it is an ideal option for those who constantly exchange a lot of information. But for regular user or for a small company it is enough to have a cloud file storage that all employees will have access to.
Bonjour Value
Since Bonjour is not so much a program, but a technology, with its help you can set up a wonderful chat that works over a local network. This information is listed on Wikipedia, so I’ll take her word for it :)
Also, one of Bonjour’s values is “contactless” access, for example to a printer. You don't have to go through the entire office to get it - just press a few buttons and you'll start printing. And you can pick up the finished printouts at any time, for example, while going on your lunch break.
But to be honest the local network is now fading into the background, which is why Bonjour is not as in demand as before.
Bonjour danger
Since the Bonjour system service is always on and running in the background, a lot of problems arise. Especially if you have an antivirus installed on your computer. Since data on the network is updated almost every second, the antivirus has to constantly monitor it, check for maliciousness, etc. This entails slowdowns in the computer and a decrease in its performance (especially if you use very “weak” PCs).
If you disable the antivirus, there is a high chance of infecting the network with a virus. It is enough for one user from the “grid” to run it on his computer malware and the entire network will be infected within a few minutes (possibly hours, depending on the virus).
Conclusion
This article briefly and superficially outlined the answers to the following questions: “What is this Bonjour program?” and “What is Bonjour technology for?” Now, if you decide to use this technology in your office, think three times: do you need it and whether it will be so useful.
Daily practical use computer equipment, a careful and attentive attitude towards it still cannot guarantee you that you will never encounter unexpected problems over which you will be powerless. Find out how to fix Microsoft Visual C++ Runtime Library error.
Unexpected “surprises” can await, appearing before users from the most unexpected angles, at first glance, without good reason. In this situation, it is useful to know, of course, the reasons that provoked them, but to a greater extent, I really want to figure out how to eliminate the problem in which the “Microsoft Visual with Runtime Library” message appears.
If you have encountered the “Microsoft Visual c Runtime Library” error, you should be charged with increased patience and an indomitable desire to get to the bottom of what triggered such an error.
You will have to spend a sufficient amount of time going through all sorts of options that indicate such a system failure.
Installing and updating Microsoft Visual C++
In pursuit of the best, many users download advertised versions of DirectX and “forcibly” install them on their computer, completely not understanding that some operating systems simply conflict with certain versions of Direct.
In particular, the tenth DirectX version cannot be successfully installed on Windows XP because it simply does not support it. If by some miracle you force them to “tolerate” each other, expect a lot of “surprises” in this case; do not be surprised that the system bombarded you with error warnings.
Check that DirectX is installed correctly and, if necessary, reinstall the program
Drivers for video card
And the last one possible reason Drivers for the video card may appear.
In general, experienced users strongly recommend periodically visiting the website of the official manufacturer of your video card to download updates. This allows you to ensure its correct operation.
If you find, it is best to uninstall the old ones, then download and install the new ones.
And finally, it’s useful to see what date your computer shows. If the internal battery fails, your computer will perform something incredible, but definitely not real time. This can cause a system crash because the system detects the hour “X”, indicating that the Microsoft Visual C++ environment that is so important to you will stop working.
So, there can be many reasons, you will have to go through all the described recommendations in turn to find your “weak” spot, which you can immediately eliminate, ensuring full operation of the computer.
All users simply need to install software such as Windows on their operating systems Visual Studio C++ 2015, however, error 0x80070666 may occur during its installation. You may see the following information in the error message:
0x80070666 - Another version of this product is already installed. The installation cannot continue. To configure or delete existing version product, use the "Install and Uninstall" icon.
In today's article we will look at what could cause this error and how you can get rid of it. Our small guide will help operating room users Windows systems 7, Windows 8/8.1 and Windows 10.
Causes of error 0x80070666 with Microsoft Visual C++ 2015
Usually, old version Microsoft Visual C++ libraries are replaced by a new one, which is installed by the user, however, from time to time this process may for some reason not happen, as a result of which all sorts of errors arise. The following may cause error 0x80070666:
- you already have this version installed on your computer;
- There are still some entries in your registry related to previous versions libraries;
- The Microsoft Visual C++ 2015 installer itself is damaged;
- your system is missing a required update;
- the system has been infected with a virus that blocks the installation of the libraries you need.
Method for solving error 0x80070666
So, let's now talk about how you can get rid of error 0x80070666 during Microsoft installations Visual Studio C++ 2015. And getting rid of it is extremely easy: you just need to remove installed versions this software, and then reinstall it. First, let's make sure you have operating system already installed VS++ 2015.
Here's an example on Windows 10:
- click Windows+S;
- enter the query “Control Panel” into the search engine;
- Find the “Programs and Features” item in the panel;
- Look carefully at the lists of installed software.
If you find the Microsoft Visual Studio C++ 2015 of the bit level you need in the list, then you already have the necessary libraries installed on your system - they do not need to be re-installed, and the installer simply tells you about it.
However, let's imagine that you nevertheless attempted to install this software again for the simple reason that some toy or program asked you to do so. It turns out that Microsoft Visual Studio C++ 2015 appears to be on the lists, but other software cannot detect its library, i.e. his initial installation went wrong.
Secondly, this is really a problem that needs to be fixed urgently. And error 0x80070666 is usually corrected complete reinstallation Microsoft Visual Studio C++ libraries. Unfortunately, we are talking not only about the 2015 version, but about all versions in general. Go back to Programs and Features and remove all Microsoft Visual Studio C++ library packages from your computer.
As soon as they are all removed, you systematically begin to install them back, preferably in chronological order. Yes, this process can take a lot of time, but in this way, with a high degree of probability, you will be able to get rid of error 0x80070666 that occurs during the installation of Microsoft Visual Studio C++ 2015.
