System Tool is a fake security program – it claims that your PC is infected with Trojans, worms and other malware (regardless of whether these infections actually exist or not).
System Tool will disable your running applications and will also prevent you from opening new ones. The aim of this rogue application is to get you to pay for the full version of the software to remove the infections that the software has “found”. Hopefully it is obvious that this is a scam.
System Tool will also change your desktop wallpaper with a large lettered warning that tells you how much danger you are in from spyware: Warning! You’re in danger! Your computer is infected with spyware!
Running an up-to-date Antivirus product (in my case Avast) was not enough to stop System Tool from installing. Not only that but I found that Malwarebytes’ Anti-Malware did not successfully remove the infection either.
To remove System Tool first boot into Safe Mode (press F8 during the boot process until the Safe Mode Menu appears). Hit the Enter key to boot into Safe Mode.
I then had to delete folders from
The folders that you are looking to delete will be a bunch of random characters with an executable file inside them (also named with random characters).
I found that I needed to delete several such folders from both of these locations.
This ended up being quicker than running a Malware scanner.
