System Tool Warning

System tool warning – Your computer is infected! We’ve all see that message pop up in the lower right hand corner of our screen. Spyware and viruses use this tactic to try and persuade users to click and install software that actually puts a virus on their system. If you choose not to click and install their “antivirus” it will nag you until the end of time. There are a few things you can do to remedy this system tool warning problem. Usually it will take all three, but when you’re done the spyware should be removed from your system.

How To Remove The System Tool Warning

Reboot to Safe Mode With Networking

You will want to restart the computer and immediately begin tapping the F8 key. This will bring up a boot screen with several options. One of these will be Safe Mode With Networking. Once you get to your Safe Mode Desktop, you can go online and download Malwarebytes. Install and run the free version of the program. When done, remove any spyware it finds, then allow it to reboot so it can finish removing the malware.

Run Microsoft Windows Update

You will then want to run Microsoft Windows Update. You will find a link to it in your start menu. Run all of the critical updates and install them. Once done, reboot the computer. When your system loads the next time, it will run a quick scan using the Microsoft Malicious Software Removal Tool. This will remove any spyware it knows about. Popular malware like Conficker, Antivirus 20009 and Antivirus 2010 will be removed.

Next, run a thorough scan using the Microsoft Malicious Software Removal Tool by going to Start, Run and type mrt and hit OK. This will check areas of you drive the quick scan does not, just to make sure you have removed everything.

Remove System Tool Warning By Installing or Updating Your Antivirus

Lastly, you will want to make sure you have installed and updated an antivirus program. Malwarebytes and the Microsoft Malicious Software Removal Tool are not anti-viruses. If you do not have an antivirus, a couple of our favorite free ones are AVG Free and aVast!

If you see the  system tool warning Your Computer is Infected! message, don’t click on it. Since the message is a trick to try to get you to install a malicious program, follow the steps above immediately and it should rid your computer of infection. Often, it takes several updates and scans to completely rid your computer of viruses–and even then, you can’t be 100% sure they’re all gone. You might even see similar messages from legitimate programs. For instance, AVG will generate a pop-up stating there is a threat to your system and ask you to click a button to move the infection to its virus vault. The messages look and read very similar. It is important to know what security software you have on your computer so you can distinguish between the two.

  1. Thanks for nice article but sometime none of given solution works in that case I format my operating system.

    • Dave says:

      I agree. It will often come down to reformatting the disk. In fact, that is what I’d do, anyway. But the average user may not be in a position to do that.

  2. Bradley Chapple says:

    Good article, but I must politely disagree with the reformatting point. There are a lot of things you can do before reformatting the disk.

    Here in our computer repair shop in Fort Collins, Colorado… I’ve probably only had to reformat a system 10 times in the last 7 years (the only reason why I remember, is because I always feel like a failure when I have to resort to that). In that 7 year span, we’ve probably removed viruses from thousands of systems.

    • Dave says:

      Reformatting, for me, is like looking in all the closets after my house has been robbed. Although it looks like the burgler is gone, I just like to make sure or I wouldn’t be able to sleep at night. Granted, these are my personal machines and I reformat all the time, anyway. I guess it comes down to what your customers are comfortable with.

      Feel free to submit an article on the techniques you use to eliminate threats. It’s a hot topic, for sure. http://www.pctechbytes.com/2009/05/12/write-articles-for-pctechbytes/
