Greetings everyone,
Yesterday as i was exploring the web i noticed a strange behaviour from my pc for example the home page changing all the time and the Norton Antivirus 2002 (latest definitions) closing every time i try to open it-including when windows start up (it had also dissapeared from the taskbar). Furthermore i noticed a significant drop in my pc's performance like quake3 etc.In safe mode i managed to run Norton and it found that the file hxdefdrv.sys was infected with the virus Backdoor.Hackdefender sth. I quarantined it but nothing changed the above behaviour. I run this repair thing from windows xp disk but the same as well as i totally erased the file. Nothing helped!It's really annoying Norton Antivirus not being able to run and the performance drop. I also checked the files processes but no differences. Any help would be much appreciated...(format is not an option since i've got pictures and movies from my digital camera!) i'm desperate, i've tried almost anything and nothing worked!
Please help...
thanks in advance!
