Decompression Bomb warning

Yesterday I installed a fresh copy of Mavericks. After the install was finished before doing anything else I ran a full system scan with Avast! Free Antivirus. It came back with the following:


/System/Library/PrivateFrameworks/MediaKit.framework/Versions/A/Loaders/MKDrive rs.bundle/Contents/Resources/bootroot.loader|>bootroot.loader.dmg


Infection Details: Error 42110 The file is a decompression bomb


Can anyone explain why such a file would be found in the "World's Greatest OS?"


Of course I isolated and then forwarded it to Avast!. A real confidance builder Apple!


The point here is don't trust anybody. Scan for virus, etc before use.

That's a file that everybody using OS X Mavericks has got. See > https://discussions.apple.com/thread/2615671


It's a false alarm, so you have to learn one thing: don't trust in that type of antivirus. If you have to use an antivirus, I recommend you to use Sophos

Because it was falsely identified by the world's worst AV junk.


The latest version of Avast found hundreds of "warnings" including "decompression bombs", "corrupted archives" that included Apple's own OS X installer, "too big to be processed" warnings and various other "unknown errors" on a Mac containing nothing other than a brand new installation of Mavericks and a minimally configured User account.


Using Avast also resulted in a non-trivial effect on system responsiveness and excessive battery drain.


Avast's most useful feature was its ability to completely uninstall itself. I recommend you do that.
