unable to scan...

[JurishzteR]

hi... can anyone tell me what to do with 'unable to scan' files? i suspect that my computer is infected with a virus because it became very slow but after scanning, there is no scanned virus and 98 unable to scan files

Nothing.

See http://forum.avast.com/index.php?topic=35347.msg297170#msg297170 this topic for more information on why files can't be scanned. You can post some common examples, file name and location and why avast can't scan them.

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

If you haven't already got this software (freeware), download, install, update and run it, preferably in safe mode and report the findings (it should product a log file).

• 1. SUPERantispyware On-Demand only in free version.
• 2. MalwareBytes Anti-Malware, On-Demand only in free version http://download.bleepingcomputer.com/malwarebytes/mbam-setup.exe, right click on the link and select Save As or Save File (As depending on your browser), save it to a location where you can find it easily later.

your PC is very slow and you can't scan so I think there is a viruse
dose taske manger is disabled or hidden files can't be shown ??
if there is something like this your PC is infected
I advice you to update avast then disable system restore and restart and inter safe mode and scan your PC
if you still can't scan PC you need rescue cd

hi sirs, well i followed the steps on the thread you have directed me and the result was no viruses found however, many files are corrupted.... how is this?

[DavidR]

Some examples of the file names, locations and why, collectively this helps us to help you, which is why it was asked for.

- Corrupted Archive file, this could simply mean that avast is unable to unpack it to scan the contents of the archive and assuming it is because it is corrupt. Even if it were corrupt there is nothing that a user can do to resolve any corruption, short of replacing the file. This I wouldn't recommend (especially if this is for archives in the \System Volume Information folder, part of the system restore function) unless you are getting problems relating to that file outside of the avast scan.

So from this you can see it relates to a particular file type, again this is the reason we ask questions.
