Hi all. I'm brand new here and found this site when I googled atapi.sys

It started a week or so ago with new windows opening on their own and if I click on a link from a Google search page I get redirected.

I've run AVG, Spybot S&D and Malwarebytes Anti-Malware but there's one thing I am unable to eliminate

Infection: "Virus identified Win32/Patched.CG"
Object: "C:\\WINDOWS\system32\drivers\atapi.sys"
Result: Object is white-listed (critical/system file that should not be removed)

But there must be a way, I just don't know how to do this. I'm somewhere between being computer illiterate and having just enough knowledge to be dangerous.

I'm running Windows XP Home, SP3 and I had to rebuild my computer (with telephone guidance from my brother-in-law) last September when it was infected so badly it just stopped being of use.

On another note - shouldI start a separate topic? - my CPU usage hangs at 100% so often that my machine seems completely non-responsive. Are the two related?

Thanks for the help anyone can give me.

Please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help". If you cannot complete a step, then skip it and continue with the next. In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the Malware Response Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the Malware Response Team.

Please be patient. It may take a while to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.

On another note - shouldI start a separate topic? - my CPU usage hangs at 100% so often that my machine seems completely non-responsive. Are the two related?

Do not start another thread...it most likely is related to your infection.
