The fix is to use the Windows 8 built in Defender, I never use other thing, aside the Kapersky provided is for Windows 7
You don't pay for , it's free, please don't tell me you purchase this board because it come with Kapersky. Aside this board was release way before Windows 8 . I have install quite few boards and I never install the Kapersky. You want a tip, install Windows 7 instead.
Kapersky is not bad, it's better than the one include with Windows 8 and free to download for Windows 7, but I have always use the one of MS without a single problem, the trick is to stay away from problems, a lot of crap come from place like C-Net and download.com, or pirated stuff left and right on the web. those free software don't come alone sometime. If you ask me I use Windows 8 since 14 months now, I have it install on 2 PCs, no choice I have to learn it as my customers will purchase it for sure. If I was you I will install Windows 7.
Why do you need an anti-virus for online gaming ? aside if you download pirated games
