I have kaspersky antivirus 2011 and im having soem problems with it.
When I open it On the top there is button "Fix Now" and next to it says "Your computer is at risk,The application should be reinstalled" I reisntalled like 5 times already and when I reboot it happens again.
So i downloaded kaspersky 2012 trail version and when I run full scan it tells me to reboot.
When i reboot, after windows logo it just blank screen with a mouse cursor. then i have to do system restore from earlier time hen it was working. Now That i dont have any antivirus cuz of stupid kaspersky I keep getting some fakes Provacy cleaners ans shit. Like vista antispyware 2011 and others.
same problem i have. it's that fake windows security scanner crap. so far whats worked BEST for me is Malwear byte's anti-malwear. and something called Rkill from BleepingComputers.com [computer support site. not breaking the no outside links, am i?] just unplug your computer, run Rkill, then start Malwearbtyes and most of it will be gone.
