This page aims to help you remove “Message from Microsoft: Computer is infected”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

If your computer has managed to get infected by a browser hijacker, you won’t have any doubt about it. Unlike viruses or malicious programs, this type of software is all about making its presence known in the most obnoxious and annoying manner as possible. It actually wants to be noticed by you and the more – the better. A browser hijacker will take over your Chrome, Firefox or other browser and set its own new homepage and/or default search engine, as well as begin to redirect you to various sponsored pages. Not to mention that all the annoying ads filling you screen can drive you up the wall in no time – that too is the work of a hijacker. And one of the latest programs of this type to be terrorizing users across the globe is “Message from Microsoft”. If you encountered this program, you may have come to the realization that deleting it isn’t quite the same as deleting any other program. You may have tried getting rid of it somehow only to find that the settings in your browser are still those that the hijacker set. But not to worry, we can provide you with the necessary instructions on how to fully remove “Message from Microsoft: Computer is infected” from your system. And you can find those just below this article in our removal guide.

What browser hijackers do and the effects they have on your system

This may be your first encounter with a browser hijacker ever and you might not really know what to make of it at this point. Is it dangerous? Can it harm your computer? Are there any hidden features you should be aware of? The good news is that “Message from Microsoft” is not dangerous in the same way that a virus is and it doesn’t have the capacity to damage your system. However, security experts classify this type of software as potentially unwanted, and indeed it’s because it has a number of features that aren’t openly made known to users. One of them is the fact that programs of this and similar types often engage in reviewing the users’ browsing history.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
  2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
  3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



  • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

Right click on the browser’s shortcut —> Properties.

NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter

Type Regedit in the windows search field and press Enter.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

The idea behind this is to collect so-called ‘traffic data’, which allows the hijacker to gain a better understanding of your personal interests. This, in turn, is necessary in order to optimize the ads that are shown on each individual user’s display. And that will finally lead to more interaction of the users with the said ads, driving higher profits for the browser hijacker developers. This is nothing to worry about, as the nature of the data collected is strictly browsing-related. However, it’s unpleasant to have these processes running in the background without knowing about them. Not to mention that they consume system resources such as RAM and CPU time, which can significantly slow down your computer’s overall performance in the long run.

In addition to that, a program like “Message from Microsoft” can also indirectly put you at risk of contracting some real cyber threats like Trojans, ransomware, spyware, etc. This can happen as a result of the endless redirections that it makes you endure. After all, there’s no telling how safe the locations you are sent to really are and some of them can be downright dangerous, containing malware of all sorts. Another reason why programs of this type are considered potentially unwanted is the means they rely on for their distribution. These are just as tricky and non-transparent as the rest of their features we’ve mentioned here.

The majority of infections with a browser hijacker – “Message from Microsoft” makes no exception – occur with the help of program bundles. Software developers bundle hijackers (alongside other ad-generating programs) with some other form of software, like say a game of a media player, etc. This other software is then typically made available for free download, which attracts users. And these users in turn download the software they deem interesting, after which they proceed to install it. Most people simply rush the process and opt for the quickest and most effortless installation feature, which is what ends in them automatically giving their permission to install all the added components as well. So the simplest way to prevent this is to just take the time to read through the installation steps and select the more detailed (manual) setup option.
