I just ran avast, when it took me to the “found items” page after scanning, I had a decompression bomb? I am trying to remove it and avast keeps coming up with “an error has occurred while processing your file.” I would like to remove this, need some help though, I am NOT very computer savvy…
Any help?

I have had some of those but it’s a bit tricky. Usually those are part of installation programs. Can you tell us what the full file path is? (ie C:\Windows\SomeRanFolder\ProgramX\DecompresionBomb)
The reason why I ask is that the file might serve a purpose (such as a computer restore file).
I am running avast again, it shut down a bit ago, I will copy and paste it in just a second.
Decompression bomb is a file that may be rather small, but decompresses to an enormous amount of data (when processed as a packed archive). Such file are not malicious per se, but they may block an antivirus program when it tries to scan them.
This kind of files is rather hard to detect (and avoid) precisely - so, it is possible that there are some false alarms. It’s not a big problem in this case, however - the “decompression bomb” announcement actually means something like “The file has a very high, maybe even suspicious, compression ratio and the AV is not going to scan the archive content”.
I’d suggest to ignore these files.
But you can change values into avast4.ini file to configure how avast should work with these files.
Click ‘Settings’ in my signature for more info 
Okay, here it is!
C:\System Volume Information_restore{CB8E16f6-86AE-4B9A-878C-8F9B38FDE4EB}\RP93\A0017300.exe$_OUTDIR\mysql\data\ibdata1
That should not be moved to the chest. Because of the name I’m thinking this is a restore point. What is your operating system? ie Vista or XP
Depending on which one it is there are different ways of clearing out restore points. Once that is done this thing should go away (supposing that it is indeed part of the restore process).
But like Tech said, you can ignore these types of things. I had a similar message from avast when scanning the Yahoo! messenger Installer.
Forget that file.
If you don’t want to be reported of it again, disable system restore, apply the changes, enable again. You’ll delete all old restore points. You can create a new one just after that.
Thank you for the confirmation tech.
You’re welcome.
