Well, it appears that Sophos may have resolved a problem with their On-Access Scanning & Retrospect 8. Â While I have not had a chance to test this yet, Version 7.1.3 of Sophos has this in it\’s release notes:
Sophos Anti-Virus 7.1.3
Threat detection engine 3.04.1
Threat data 4.50, February 2010
New in this version
This version includes fixes for the following problems:
- DEF 47375: On-access scanning causes increased scanning time with EMC Retrospect.
- DEF 52975: Scans started from the Sophos Anti-Virus Mac OS X GUI attempt to scan Stuffit archives, although scanning for this format is not supported.
See Sophos Anti-Virus for Mac OS X release notes for more details.
