eicar scan

Odpad Avast 4 for PDA

Engine version 4.1.19
Database version 1.4
Windows Mobile 6.1
These questions may have been asked before but I can’t find a definitive answer.
The following anti-virus test files are present on both the internal memory and on the storage card: eicar.com eicar_com.zip eicarcom2.zip

  1. Running a manual scan picks up eicar.com but not eicar_com.zip or eicarcom2.zip. Is this expected? i.e. avast cannot detect virus signatures in an archive format.
  2. Does avast run in the background continually monitoring new files or does the user have to manually scan? Nothing is detected without a manual scan.

Zipped files will [in majority of cases] not spread unless, extracted. Avast’s manual scan upnpacks all compressed files therefore, detection of the said file.

Thanks for your reply.
So . . .

  1. There must be a bug as a manual scan does not unpack archive files. Therefore avast cannot currently detect virus signatures in an archive format.
  2. avast doesn’t run in the background; all scans must be manual

[s]Huh? Does not unpack? Mine was detected [see screenshot below]

Do you have any antivirus(es) before/alongside avast?[/s]
