found a decompression bomb - now what?

Viruses and worms

I found a decompression bomb while doing a boot scan, and hitting delete or delete all didn’t so any good - I just got the same Error 42110 message over and over again. Any advice would be appreciated.

You have to go to resetting your restore points to a point before you came infected or delete the restore points before you can delete, but before you do anything upload the file for analysis at virustotal’s and give us the results.
How did you get the decompression bomb anyway?.. from clicking on an image?

Thanks for the replies. I don’t how I got the bomb and I don’t know how to upload the file to VirusTotal, since I’ve only found in during the boot scan.

Quote from Igor…

- decompression bomb is just something that unpacks to an unusually big amount of data even though it's rather small (i.e. has a high compression ratio, for example). It's nothing to worry about, you are just informed that avast! will not try to unpack the archive (you may not even know that it's an archive, but it seems like it is) because it may take VERY long to process.

Pardon my ignorance, but why would my anti-virus software try to unpack it anyhow? Are you saying that the bomb is made to do damage when an ignorant anti-virus program tries to scan it? And that because Avast (and Malwarebytes and Microsoft Windows Malicious Software Removal Kit too, I presume) are too smart to do that, the bomb can’t “explode”?

Thanks again.
