Kaspersky finds malware, viruses and Trojans, the other (freeware) - programs have not found (AVIRA, Microsoft Security Essentials and Norten), system performance does not affect the work still playing noticeably but has its pitfalls in detail. Some programs on my machine have suddenly stopped working, and it's not necessarily intuitive to figure out which part of this Kaspersky now impossible. As has just helped Kaspersky quite ausschalten-> program goes! (Aha, Kaspersky is at least responsible) and then gradually try to functions by the program works. Can sometimes take and is annoying. Otherwise top! (Ultimately is indeed the security front)
