I was buy Kaspersky because of reading a very good reviews, but to my Suprise after installation of Kaspersky antivirus, my laptop is started to shut down. I believe that Kaspersky dont expect from me to be extraordinary expert, but what I expect from Kaspersky is that he simply do his job without problems. No matter what I try my computer was keeping to shutdown and that was so awful! So I buy my good old Symantec Norton and there was no problem. Its a shame that so big machine like Kaspersky cant solve this problem once and forever !
