I have used kav on my system sometime ago and it use to cause all kinds of problems on my machine, so i had changed it to something else. With kav i had comodo firewall, cyberhawk, spywareterminator running alonside it. Week ago i tried to trial Kis 6 everything went smoothly until the next morning. My machine wouldnt even boot to windows so i had to take it of. I didnt have any other programs running alonside with it. So my question is: Are Kasperskys products stable or is it my machine? Or is it software issues? I am not bashing kaspersky i am just wondering why i cant seem to to be able to use their products.
