Scan't scan a file
« on: June 10, 2009, 11:05:50 PM »
Using 4.8 during a scan, receive a window that a file can't be scanned (it's a kept email msg in a folder in Thunderbird) which reads:

path -- "partno_0#1551300465/partno_0#3771491968/partno_0#3519077097/f/learning to 8751946/learning to like mouthfulls of salt-ndsp: Was a mistake made? What 661048528.   

Unable to scan - the file is a decompression bomb."

Presumably the part numbers relate to something added by Thunderbird as an ID for each msg?  And if so, the user certainly can't relate to it.  I searched the subject file for "salt" and apparently that's a word used whenever a photo is attached?  Also searched for "was a mistake made" and found nothing.

In the window that opens attempted without success, delete, delete on reboot, move, chest, and scan.  Any ideas as to what this means and the danger of keeping such a msg?

Guess I should have simply quoted the entire text from the log:

Decompression bombs are not much of a problem:

Decompression Bomb, a file that is highly compressed, which could be very large when decompressed. This used to be a tactic long ago to swamp the system, also see
The name really is the most dangerous thing about this and I wish they would change it or simply not report it, a real PITA.

Files that can't be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.

I think there is nothing to worry about there.

Hope this helps,

Thanks and it's as I thought as it's been dormant for years.  The trouble is that frequently when I plug the thumb drive into a foreign computer it's program indicates a virus which is annoying -- And I believe it's caused by this msg, so would like to find a way to identify the msg and delete it.  FYI Thunderbird doesn't keep each email in a separate file, so could only search for the verbiage displayed in the report, and that didn't do it.
