Need help on avast scan report

Viruses and worms
1

I keep receiving the following messages in my scan report and would like to know if I need to be concerned about them.

  1. Win32:Agent-GKD [Trj] (0)

  2. The file is a decompression bomb. (42110)

  3. Archive is password protected. (42056)

My O.S is Windows XP Home Editon version 2002 Service pack 2 and am using Avast ver 4.7 Home Edition

Thanks

  1. What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?
    Check the avast! Log Viewer (right click the avast icon), Warning section, this contains information on all avast detections.
    I assume this keeps coming back (same file name and location (?)) ?
    If so, if you haven’t already got this software (freeware), download, install, update and run it, preferably in safe mode.
    Ewido, a.k.a. avg anti-spyware

  2. This is just an archive file that when unpacked for scanning would be very large and in the past this type of thing was used to swamp system resources either leaving the system vulnerable or crashing it. However, this is no indication that it is malware, please give the file name and location ?

  3. Many programs (usually security based ones) password protect their files for legitimate reasons such as AdAware and Spybot Search & Destroy, there are others (and avast doesn’t know the password or have any way of using it even if it did know it).

When you run scans with the above programs and you delete harmful entries that they detect, a copy is kept (in quarantine/restore/backup) in case you need to reverse what you did. These are usually password protected, you should do some housekeeping and delete old backup/recovery/quarantine entries (older than two weeks or so), this will reduce the numbers of files that can’t be scanned.

By examining 1) the reason given by avast! for not being able to scan the files, 2) the location of the files, you can get an idea of what program they relate to. You may need to expand the column headings to see all the text.

Files that can’t be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.
