Hi! Sometimes after i scan, the report states that “this is a decompression timebomb”
What does it mean? When i try to “chest” it, an error will occur. Pls Help!
Thanks in advance!
Hi rodzthomas,
http://en.wikipedia.org/wiki/Decompression_bomb
The detection can be a false positive- avast! detected an .iso image as a decompression bomb on my computer this morning. I know it’s a false positive because it was an image of a working PCLinuxOS live CD!
Big files like this (CD/DVD size) are too big to move to the chest. Either ignore the detection if you’re sure it’s a legitimate file or delete the file directly- it may also be too big to move to the waste basket if you’re in Windows.
If it’s a legitimate file, the avast! people would want to remove the FP detection, but if it’s a very large file, sending it by email would be out of the question. You could mention the name of the file, how it was created, where it was downloaded from etc. here: that might help remedy any FP.
If had been a smaller file, you could’ve uploaded it to VirusTotal to check the detection.
Hi Frank! Thanks for the reply. It was a nero file (Dont really remember.Sorry) I will put up more details on the next time i get this message. I do get stuff like, the file is corrupted and when i try to delete or move it to the chest, an error will occur.
Sorry for not being clearer. Will keep this in mind on the next scan and if something pop’s up.
ahh… i finally did the scan. I tried deleting the last file and an error accured. Kindly have a look.
Thanks.
The ‘corrupt’ archive in NeroBackItUp I don’t think is a problem. More likely avast! just can’t read it. Unless somebody with more knowledge tells you otherwise, ignore similar messages.
The ‘decompression bomb’ warning seems to be a DVD data file: safe to ignore. If one of those .VOB files is less than 10MB, you could email it to avast! mentioning it’s a false positive, although they may well be more like 100MB+: far too big to email.
avscan.dll is an AntiVir file. Do you still have AntiVir installed? Two AV programs will conflict: if you’re going to use avast!, you’ll need to uninstall AntiVir.
What is the full location of this entry:
E:\Computer Stuff.…\avscan.dll?
There are two more in System Restore you can ignore: If you no longer have AntiVir, avscan.dll will get flushed out of System Restore as new restore points are created.
Yeah ur right about the mail thing. With regards to Antivir, i have uninstalled it previously when a problem accured. The umbrella just didn’t open. Really!
So in turn i found Avast! and its been working great until that issue i had. I also created more restore points after the uninstall of AntiVir.
The location for E:\Computer Stuff.…\avscan.dll is located on my partition and that file could not be found when i wanted to delete it manually. Even after “show all Folders” was ticked.
I will go home and check out the “…” after E:\Computer Stuff\
Thanks again for ur help!
Hi :
To COMPLETELY REMOVE AntiVir/Avira from your computer, follow the
Info at www.avira.com/en/support/av7_upgrade_tools.html . That
includes using the "Registry Cleaner" Tool and the appropiate
"Uninstallation Package" .
Thnks. Will try that
Please, post back the results 
hi Guys. I finally did the uninstaller for Avira and it didnt work. First time i had some program’s running and it said to “close all running…”. Then i closed all that was open including my Avast! and it still said the same thing. Any other ideas?
Did you try Control Panel before?
Yes. I uninstalled Avira through the “add/remove” section.
And then boot, and then used the uninstall tool (registry cleaner) for it?
yeah i just did it. Gonna run Avast! scan later on… but when i started my com earlier, it said that in “Lacals…delus.exe” cannot be found. What is that? Sorry, Im learning
Who said that?
Can you post a screenshot of the message?
The only way to know what is it, will be knowing what is behind the … on the file name.
I tried to get a screenshot. The thing is, It happened just before windows loaded. After that, windows loads as usual. Im using windows XPp2
here’s a link on that file i mentioned
http://www.file.net/process/delus.exe.html
it seems its related to antivir.
Any useful information into Control Panel > Administrative Tools > Events, specially ‘Errors’.
Sorry for the late reply. Will check it tonight… I did a full registry cleaning and that prompt did not happen again… but i still will check the “specially errors”
Thanks again…
i couldn’t find the section u mention. But this is the latest scan…
