Full Scan was completed on my Mac with OS X Lion 10.7.5 + Avast!7.0 (39134) - scan report contains Warnings such as:
Error 42110 The file is a decompression bomb.
Error 42120 ARJ archive is corrupted.
Good Mac-Forum Experts,
Am regretful that I am so ignorant, but therefore, I need to ask you - -
1. What is "a decompression bomb?" I mean, what are the issues, and what criteria would produce this classification on a file listed in OSX Lion's Get Info panel as, Size: 131,722 bytes (4 KB on disk)? This file bootroot.loader, is found in the path,
and, does anybody know that this is a legitimate file, to find in that path in OS X v10.7.5?
2. First, what is an ARJ archive? Does OS X Lion natively include any ARJ archives?
3. One zip file was flagged with HTML:Bayfraud-AB [Trj]. Does Avast provide a KB or site that explains what its malware ID s (names like this one) are, in terms that enlighten us on the serious effects of the malwares? Is it possible that this is a Windows malware that does not harm our Macs? I also have in this report, something ID'd as W32:Gen or something like that, probably it is a Windows-targeted item, but can it hurt my Mac?
How is one to know which are Windows-only and harmless to Macs?
If these are too many questions for one posted query (although, not unrelated to each other), please illuminate my ignorance on any one of them…
