Data1.cab decompression bomb

[system]

Hi, I just ran a thorough system scan, and afterwards, I got a notice that Avast! could not read the Data1.cab file in my After Effects install directory, and stated that it was a decompression bomb. However, the issue is that it is reading this from the Data1.cab file that is in the ZIPPED copy of my after effects pro file, whereas in the unzipped directory avast! has no problem with it whatsoever. Is this simply a case of trying to read a huge compression file within a compression file, especially since this particular cab file is about a gig and a half, or should I be worried?

I read up on decompression bombs and I heard they can be annoying. I installed the after effects program several weeks ago and have not noticed any strange activity on my system.

The reason for my concern is that it is a cracked copy. However, I ran scans over the keygen when I got the AE file weeks ago with avast, as well as my two anti spyware programs, and it didn’t notice anything with that. The rest of the files in the install are pretty much what comes with a legitimate Adobe install disk, and I know that Adobe’s cab files are normally pretty huge. I’m hoping the issue was simply that the file is zipped.

Any help or insight on this matter would be greatly appreciated.

Should I be worried?

Generally, there is not need to be worried about. 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.

I’d suggest to ignore these files.
But you can change values into avast4.ini file to configure how avast should work with these files.

There is no space here for piracy. Sorry.
