What slow downs are you experiencing, PC or web browsing issues?
Have you tried these combinations:
KIS2012 (using SafeRun + Anti-Banner), IE9 with Fanboy AdBlocking TPL
KIS2012 (using SafeRun + Anti-Banner) if compatible, Chrome with ABP
BZP + ZAL, Chrome or IE9 with extensions mentioned above.
I found Chrome to provide better protection against Exploits and Malicious downloads, than compared to AVG LinkScanner. As for AVG LinkScanners web page rating, you don't really need those useless you visited uncommon websites.
Theoretically, there could be an exploit here on MalwareTips unknowingly, even if AVG LinkScanner gives the green light on the website, and you're going to be saved by BZP or KIS, depending on which you're using.
