It's quite hard to detect such files reliably, so it's possible that it gives some false alarms ocassionally.

So 4.5's new ability to at least try to detect such bombs is certainly a welcome addition.

Quote #1 Mon Dec 21, 2015 4:38 am I just downloaded AMD Radeon Crimson 15.12 and did a full system scan using Avast, and I got this:A quick Google search for 'File Decompression Bomb' brings this up:"A cimmanifest decompression bomb zip bomb, also known as a zip of death or decompression bomb, is a malicious archive file designed to crash or render useless the program or system reading it. It is often employed to disable antivirus software, in order to create an opening for more traditional viruses."Before even running the full system scan I've noticed that whenever I run the installer it takes a LONG time (about 30 seconds, I'm not sure) for anything to happen. I initially chalked it up to my system bogging down and aborted the process after every attempt to install the package, but after the scan, I'm not so sure I still want to install it.Any thoughts?

Strange result on my latest Avast scan: C:\WINDOWS\Internet Logs\tvDebug.zip\tvDebug_2009-12-15-18-56-36.log Unable to scan : The file is a decompression bomb I know that a decompression bomb is a zipped file that when unzipped releases a very large amount of data but I don’t know whether this file is legitimate and the result of the scan is (yet another) false positive and or if it’s potentially malicious and should be deleted. I don’t recognise the file itself but I’m also confused that its an Internet Log – I use CCleaner at the end of each day so shouldn’t all internet files be deleted? And if it’s a log, what’s creating it? Please could someone advise what I should do with it and whether it’s safe to delete and if so, the safest way to do this? Thank you.

It contains details of ZA activity and should only be a small size 5 - 25Mb. I'd say it is a false positive, but if you wish, you can delete it. Avast tends to label things in that way when it can't access the file to scan it. To prevent it reappearing and taking up disk space, you can shut it down. This will explain. That said, it does no harm and can be left as is. Come down off the ceiling yet? If your problem is solved, here's how to sa
