Ok so I noticed you guys are the best to ask for help. I started having problems yesterday after installing a clean newest version of BSPlayer in Windows XP. The problems consist of IE crashing on 90% of addresses, except google, for example and Firefox getting redirects to obscure advertising sites. I also got 1 BSOD (reset happened too fast, didn't see the address or the dll) and I have to mention it's the first one I got since I have this computer over 1 year now. The system is a Dell XPS 1530 notebook, running dual boot XP SP2 and Vista. IE version for XP is 6. Vista doesn't seem affected. Mozilla is the latest. I am also running Zone Alarm and Avira Free latest versions. Ok so initially I performed a scan with Zone Alarm's malware detection kit and it showed around 30 adware/cookies/spyware which I then deleted. Since the problems continued I decided to take the 8 steps you suggest, and these are the results I got. Any thoughts or suggestions would be highly appreciated. Thx.
