Sophos Anti-Virus for Windows 2000+: high CPU usage on a computer with Microsoft AutoRoute 2004

Sophos Anti-Virus for Windows 2000+, version 5, can encounter high CPU usage problems on a computer running Microsoft AutoRoute 2004.

When AutoRoute is opened, the computer can hang with a CPU usage of 100%. This is because the on-access scanner persistently scans the file C:\Program Files\Autoroute\Data\EURArts.its.

What to do

Exclude the file C:\Program Files\Autoroute\Data\EURArts.its from on-access scanning.

If you need more information or guidance, then please contact technical support.
