Poor performance seen on computers using Sophos products

If one or more of your computers are running excessively slowly and/or you are seeing extremely high CPU or memory utilization, there could be several possible causes.

What to do

The following table provides links to knowledgebase articles that describe possible causes.

Sophos product Issues to check
Sophos Anti-Virus for Windows 2000+ Is it configured with the recommended settings?
Sophos Anti-Virus for Windows 2000+ RouterNT is showing high CPU usage
PureMessage for Microsoft Exchange Information store scanning problems

Occasionally, third party software running on the same system as Sophos products can reduce computer performance, for example Microsoft AutoRoute 2004 with Sophos Anti-Virus for Windows 2000+.
