Msfeedssync.exe is something that most PC users will never come across—especially if you don't use Internet Explorer. But if you get errors, or concerns from your antivirus software that Msfeedssync.exe is causing problems, learning how to remove it can be a good idea. It's not typically a virus, but it can appear as such at times.

Whether you have the Msfeedssync.exe error or not, we wouldn't recommend using Internet Explorer. It's outdated and unsafe for browsing much of the internet -- especially older versions. We would instead recommend a fully updated version of Google's Chrome, or Mozilla's Firefox browsers.

What is the Msfeedssync.exe Virus?

Strictly speaking, it isn't one. Msfeedssync.exe is a software component of Microsoft's Internet Explorer web browser. Its full name is the Microsoft Feeds Synchronization and it's used by Internet Explorer—particularly older versions like 7 and 8—to update in-browser RSS feeds which have been given permission to automatically update.

It shouldn't cause any problems by itself, but there are times it can stumble when trying to update and Windows can, in turn, issue a warning about it. We have found some instances of anti-malware software tripping warnings when Msfeedssync.exe tries to synchronize Internet Explorer feeds, too. The cause of those anti-viral warnings isn't exactly clear, but it's possible that they appear due to security concerns over Internet Explorer itself.

How Does Msfeedssync.exe Work?

Msfeedssync.exe is a file that executes at the whim of Internet Explorer's RSS feed synchronization system. If you have toggled on that option to automatically update and sync your RSS feeds in Internet Explorer, it will trigger at the allotted time(s) to make sure they remain up-to-date.

It's a fairly basic .exe file in any other respect, executing a predetermined function using pre-written step-by-step instructions.

How Do I Know if I Have Msfeedssync.exe?

Most Windows PCs running Windows 7, 8.1, or 10 will have Msfeedssync.exe, even if nobody on it uses Internet Explorer. It's a bit of legacy code that can typically be found within the Windows/System32 folder.

To see if you have the file, you can navigate to C:>Windows>System32 and look for msfeedssync in the Name list. Alternatively, use the Windows search bar to search for Msfeedssync.exe.

You may also come across Msfeedssync.exe if an error message associated with it appears, or if your antivirus picks up on it as a potentially problematic file. In either case you'll know you have the "Msfeedssync.exe virus," even if it isn't really a virus.

How Did I Get Msfeedssync.exe?

In almost all cases, this particular executable is installed along with Windows 7, 8, 10, and in some cases earlier versions, too, depending on your particular Windows install. There haven't been any legitimate concerns over this file in many years, so we feel confident that it's not a virus in almost all cases. If you are convinced that your MSfeedssync.exe has been infected, though, it may have happened via another piece of malware that you contracted from visiting a dodgy website, or by opening an infected email attachment or link.

How Do I Get Rid of Msfeedssync.exe?

Unless you are encountering error messages or antivirus alerts about this particular file, we suggest you just leave it alone. It's an old file that has no bearing on modern web browsers or Windows use, so unless you like to dig out old versions of Internet Explorer particularly to view RSS feeds with, it's unlikely you'll run into any issues with it.

Internet Explorer

That said, if you do find it problematic, or just want to be rid of it on the off-chance it could cause a security concern on your system, you can disable and remove Msfeedssync.exe.

  1. Open Internet explorer and select the cog-icon in the top-right. Then select Internet Options.

  2. Choose the Content tab along the top menu bar.

  3. In the Feeds section, select Settings.

  4. You should see an option to toggle On or Off Automatically check feeds for updates. Make sure the toggle is in the Off position.

  5. Close down all menus and restart Internet Explorer.

If this doesn't seem to have solved your problem, you could disable Internet Explorer entirely. Here's how to do so.

We suggest you use caution when turning off Windows features, as some of the features that you can turn off are likely to interfere with the performance of your computer. Stick to these instructions, and don't turn off other settings until you have researched them completely.

  1. Search for Turn Windows Features on or off in the Windows search bar and select the corresponding result.

  2. Scroll down the list and look for Internet Explorer. Windows 10 users will only have Internet Explorer 11, but older versions of Windows may have older versions of IE too.

  3. Toggle off any versions of Internet Explorer. Then close the menu and wait for the changes to be applied. Restart your PC if requested.

How Can I Avoid Getting the Msfeedssync.exe Virus?

Since Msfeedssync.exe isn't a virus, your best bet to avoid anything like it or viruses masquerading as it, is to use best practices to avoid any virus.

Here are some important considerations to make to stay safe on your PC:

  • Update your anti-malware software regularly. Keep your antivirus software and malware protection up to date. Most antivirus software will update itself frequently, but we suggest making sure that it updates at least once a day and better yet, multiple times a day so that you are always protected.
  • Be wary of new applications. Don't blindly download or install new applications, especiailly if you didn't manually trigger them. This is one way that viruses can make their way into your system
  • Don't use email attachments or click links wantonly: Email attachments and infected email links are a common way of spreading viruses. Make sure that you don't open attachments or links unless you are absolutely sure they aren't malware infested.
  • Stick to well known websites. Stay away from websites you're not familiar with to avoid man-in-the-middle attacks. Also, never click on popup ads that might appear while you're on any website. Clicking them may cause you to accidentally download other suspicious files such as malware or exploits.

You may also consider using a more modern web browser, since Internet Explorer is no longer supported by Microsoft. Chrome is great, but Microsoft's own Edge browser is designed as an IE replacement and can bring over all your bookmarks and other information with ease.
