Avast found 6 log files to be a decompression bomb, is it safe to delete these files, what should I do or should I leave them alone.
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.
(quoted from Igor: http://forum.avast.com/index.php?topic=15389.msg131213#msg131213)
I’d suggest to ignore these files.
But you can change values into avast5.ini file to configure how avast should work with these files.
