Kavos Aftermath?

Ever since this:
http://forum.avast.com/index.php?topic=56081.msg476009#msg476009

I’ve been having wierd problems, even though it’s supposedly been solved. The main one was that WMP was running real slow, and would sometimes disconnect me from the internet while using it, even though I ran a program called fix WMP, which replaced all the dll files. I switched to Winamp. In the meantime, I’d been running avast and malwarebytes, and came up with nothing over and over, even though I was having problems here and there that seemed virus related. Today, my wireless connection stopped picking up signals, and my avast won’t run it’s virus scan anymore, not even in safe mode (the program loads up though). A system restore didn’t work. I am in my XP install right now, and am running AVG, which is at the end of my Windows 7 install, and has found nothing. I am gonna run AVAST from here too. So frustrated at what seems like an invisible virus.

Would you scan with dr.web cure it! then reply wait run radix anti rootkit scan the give us the report

Actually the lack of wireless connection was caused by something else.

I still don’t understand though the problems I have with WMP. It’s usually very lightweight, right?
