'Decompression Bomb' file found in anti-virus scan. What is it and what to do?

Hello,
I just ran a scan using avast antivirus after deleting my restore points to rid my computer of malware that was in the restore points. The malware is gone but in the list of files that could not be scanned was something refered to as a decompression bomb. The file is in my documents and settings folder and says something about Opera and user profile in the file name. What is this and what should I do? Let me know if there is any helpful info I can provide.

Thanks, Liddy

As far as I know, a "decompression bomb" is just a file that maliciously expands to fill up your entire disk if you click on it. If you know the file name and location, just delete it and run another scan. If it is a file you consider useful, then do not delete it, sometimes such messages are false positives.

If you're unsure, post more details about the message from avast, and the exact name and location of the file.
