Title: zip archive is corrupted
Post by: simonr on December 13, 2004, 10:08:38 PM: I have recently installed advast 4.5, on scanning found several viruses which were succsessfully moved to chest. On finishing scan several files could not be scanned most of which i reconise. Two of which were windows sytem files; C:\WINDOWS\SYSTEM32\MSrev 23.dll\noname.xml and C:\WINDOWS\SYSTEM32\MSrev 43.dll\noname.xml. RESULT for both: unable to scan ZIP archive is corrupted. Do i need to worry about these files?

Thanks simon.

It would be wise however, to check the offending/suspect file/s at: Jotti - Multi engine on-line virus scanner www.virusscan.jotti.dhs.org (http://www.virusscan.jotti.dhs.org) if any other scanners here detect them it is less likely to be a corrupt archive or false positive.

No, talking shortly, no.
You should give us full name and path of that files.
No all files that can't be scanned are dangerous. In fact, I think only few of them will be, in fact, viruses.
Better is send the file (or add) to Chest and wait for further analysis.
You can also submit the file to on-line scanning. There are a lot of references here in forum where you can get the best on-line scanners.
