Hey everyone, received this error the last 3 days but before that all worked fine.

Any ideas why this is happening?

Hey there! ClamAV seems to struggle with Flash files, as this has been going on for some time:


From what I am seeing, it either isn't guessing the length of the file correctly, or there is an issue with that particular file that needs to be examined.

Thanks CPRex, but not sure why it is trying to scan flash files as I have none on my server that I am aware of. Maybe it is a hacker or spammer trying to send an email with a flash file?

Thought I'd mark this as solved as it hasn't happened again since this post.
