Thanks for letting me join your community!! Its been a great help in the past just browsing the forums but now I've had to register because I've gone and properly knackered my computer.
I'm running Windows XP Media Centre Edition SP3 and use Registry Mechanic and AVG Internet Security. My problems started when I noticed my internet links were getting re-directed to all sorts of ridiculous sites ("The Cow Survey" for one). Thinking I had a virus I then noticed I couldn't update my antivirus software or even run the check disk or defrag tools. Now I can't even access the internet, have boot up failures and sometimes get the error message "Registry editing had been disabled by your administrator" (possibly in reference to virus scans). AVG has also identified and cleaned some small trojans but some hidden files and drivers are still present under the rootkit heading. In summary I think my PC is royally f****d.
I understand I may need to get hold of Hijack This and Combifix but wanted to ask the experts first. Please explain things to me like I'm simple because I really don't know what i'm doing.
Please let me know if you need any more information and please please try and help me, I'm in my final stages of university and really could do without smashing my computer through a wall.
