BleepingComputer.com: Desktop Anti Virus Message

Good people

I know nothing about computers, and I am having a problem. I am at work and while looking at the web the computer got infected. Its only a small company and there was nothing in place to stop it. I paid £40 for Norton, downloaded it and scanned. It got rid of the problem, but I still keep getting your computer has a virus messages. Also and the worst thing of all is I have a blue desktop now with (Your computer has been infected by spyware) In the propeties its down as a desktop picture (if you know what i mean?) I cant delete it. What do I do? My boss is back in tomorrow and am poohing my pants!

Yours sincerely

Stuart

WElcome to BC aaahhhelp. Diapers are on hand ..
start with checking for malware causes to your problem.
Install Super Antispyware. Run it in safe mode. Allow it to quarantine whatever it finds.

Run the online scan for Bit Defender in normal mode. Allow it to quarantine whatever it finds.

After that please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. About half way down are instructions for downloading HijackThis and creating a log.

When you have done that, post a log in the HijackThis Logs and Analysis Forum, NOT here, for assistance by the HJT 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 HJT 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. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

Please be patient. It may take a while to get a response because the HJT 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 made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT 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 HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log here.

After posting a log you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc.) unless advised by a HJT Team member. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

Do the pop up alert messages look like any of these?

If so, then follow the generic instructions for using SmitfraudFix in BC's "How to remove the Smitfraud/Generic Zlob".
