Since you run windows 8 for me the best solution is:
Qihoo 360 Internet Security (QVMII active also) + windows 8 smart screen filter, is by far better than Kaspersky
Kaspersky is only better at clean up because (instead of just delete a virus) it disinfect it.
If you worry about web filter , simply add K9 Web protection, or McAfee Site Advisor or even W.O.T. and you'll be super!!!
