Sumana, as I told you before, no antivirus is perfect, the lighter one may not be as effective, the heavier ones have more functions and scanning engines. You seem to have almost tried them all. When on internet make sure that you don't have other applications running at the sametime. Also, once in a while, when things are getting slow, with CCleaner, clean your temporary internet files.
I am not 100% sure they are lighter, but a lot of people use Panda or Bitdefender. I use F-Secure but your certainly would not like it.
I had never heard about Vipre but if it does not let you go on Internet you may as well do without and stick with the known products.
As I said, when on the net, do not run other applications and clean your temp files when it is getting slow.
I remember telling you about Startuplite which prevents the running of unecessary applications from running in the background which helps to preserve your resources while playing games. Did you use StartupLite?
Also, I told you about CCleaner to clean your temporary files, once in a while during your game play, again to regain some resources.
You have a good fast machine with lots of RAM, so if you do the above, there is no reason why Kaspersky Internet Security should cause you any problems. Last year I had KIS and it worked fine for me.
