F-Secure Anti-Virus can detect certain compressed/archive files
that have a big compression ratio (for example 1 megabyte archive
or compressed file that expands into tens of megabytes of data)
as 'Mail Bomb'. This does not mean that any infection was found
in those files, it's just a warning. If you have a file detected
as Mail Bomb, please exclude it from scanning for both On-Access
and On-Demand scanners of your F-Secure Anti-Virus.
