PC Security Test 2005 is the tool you were looking for to guarantize the security on your PC.
It is divided into three different parts:
Hacking, Virus and Spyware. Each one is focussed in the name they have (it is easy, isn’t it?) So if you want to test only one of the three aspects, you can do it.
At the end of the test, the program runs a protection final test offering results with percentages and it determines the security level of your PC.
