System Tool Removal from your Computer

System tool is a member of a specific family of malware such as "Rogue Security Software" or crimeware. It is the software that pretends to be an antivirus or other such protection program for the user’s computer against malicious software, at the same time damaging the user's computer in an attempt to trick, deceive or intimidate money from the users. Therefore, it is a division of a broader group of fraudulent malware such as ‘scareware’. 

Generally, the rogue security software and its types come into the computer with online ads and false banner ads with some massage like "Your PC may be infected! Verify Now". Those who carry out the instruction finish up with a set of tools installed on their PC. Some versions are completely independent and install without user’s knowledge or consent. The system tools will then "search" your computer and generates lots of false ‘detections of viruses’.

It then announces something like ‘Your PC is severely infected; get the full version to repair this problem." However, there will be no full version as such!  What you get for your money is nothing but a set of spyware. But that's not all. It will always annoy you with continuous "find", can block your functions saying that functions are "infected", and stop you when you access the web sites giving genuine protection against malicious software.

Get rid of it as stated below.
1. Restart the computer and press F8 until you see ‘list of boot options’.
2. Choose ‘Safe Mode with Networking’.

3. After starting the system, start your antivirus, scan and delete infected files.
4. If you have no antivirus, download, install and update trustworthy anti-malware programs. Redo step 3.
5. Restart with default start options.

If this does not work, remove the system manually with the help of an expert.
