Length of time to do a full antivirus scan

Comodo Internet Security - CIS AntiVirus Help - CIS
1

For various (mostly due to a requirement to run old embroidery software) reasons, I sometimes use an old XP SP3 PC.

I occasionally connect to the internet.

I have always used the Free Comodo Firewall along with either Avast or AVG antivirus. Due to conflicts between Avast or AVG (never both together :wink: ) and Comodo Firewall, I decided to completely uninstall the antivirus I was running and try the free Comodo Internet Security (including antivirus) instead.

One of my first tasks was to run a full antivirus scan but as it has only reached 2% after 17 hours, I have stopped it. A full scan with avast or AVG may take between 1 and 2 hours, at the most.

  • Is this normal for Comodo antivirus?
  • Is there anything I can do to speed up the scan?
  • Is there an alternation option / package I can run with Comodo firewall?

I kept the UI in the foreground rather than sending to the background as I assumed that would be fastest.

Thanks for any guidance that is offered.

Do you notice abnormal CPU usage with ‘cavwp.exe’ process? Try disabling Decompress and scan compressed files option in Advanced Settings > Antivirus > Scans > Full Scan. There are known issues with some files triggering a stuck in the scan. They’re going to update the engine in the next release(s).

Hi,
Can you please try to run Quick Scan and see if even that completes?

Thanks

Many thanks for the replies.

A Quick scan is very quick and works okay.

Taking the advive from qmarius, the scan is currently at 42% after 1 hour and 10 minutes so a lot faster than previously.

I appreciate the help.

It’d very helpful if you could identify the exact file that causes trouble & provide it. Additionally, check if there’s any dmp file under:
%SystemDrive%\ProgramData\Comodo\CisDumps

The Full scan was now complate after 2 hours 27 minutes - perfectly acceptable for this old system, thank you again for the help.

I guess what is meant by “%SystemDrive%\ProgramData\Comodo\CisDumps” on this old system is “c:\Documents and Settings\All Users\Application Data\Comodo\CisDumps” and yes, I have a couple of large files in there but they appear to refer to the installation as the time stamp on them is much earlier than when I started the Full scan.

The Full scan I ran earlier didn’t fail, it was just taking an extraordinary amount of time so in the end I stopped it.
