A great program, it would definitely deserves 5 stars, if not the live mode would. I bought and installed the program. In advance I have to say I have a i5 processor and an SSD hard drive, so all in all a fairly brisk computer. This means a program start takes about 1-2 seconds. After Installiation the purchased Spybot and active live system a program needed at least 15 and more seconds. The computer has to be filled if I run 20 Trojans in the background. Thus I have the purchased version uninstalled immediately and installed the free version without Live system. The Live system needs too many resources or is too slow. What I found very positive, the company has the money again sent me good, because I was not satisfied with the program.
