As subject says, some of the gzip files are detected as possible ZIP-bombs. In particular, it\'s these files:

DMSNH3SO2A1B_19182082N.gz
ozone_hadcm3_1919_2082.gz
SULPC_OXIDANTS_19_A2_1990.gz

I see three possible solutions to this:
(1) Make the antivirus skip the project folder or individual files
(2) Change the internal structure of the gzip files to avoid being seen as a possible ZIP-bomb
(3) Contact the antivirus company to try resolving it on their end

I guess alternative (1) is most relevant, but could option (2) be a way to go also?
Last option could be done by me, but don\'t know how successfull it would be, since updated gzip parameter files might create the same problem over again.

Any ideas?

Been there, heard that. :)

Go for 1); skip the entire BOINC folder, both with prgrammed and \'on demand\' scanning.
Which is the standard recommended proceedure for all problem AV programs.

According to another cruncher who posted on the php board, his AV company said that a \'bomb\' is a VERY large zip file, that is too large for the program to check, so it \'gets the jitters\'. Or words to that effect.

2) is out, because then the programmers would be forever changing the structure each time an AV company come up with a new \'bright idea\'.
BOINC has already had to be changed recently to get around a problem created by a recent \'bright idea\' by, I think, Mcaffe.
