Have to report a problem - I use the 'Automatically archive application' during updates option and I have found it goes incredibly slowly during the packing old application process *unless I temporarily disable McAfee AntiVirus*
In this case I have to disable VirusScan On-Access Scan during that process. I can re-enable the On-Access Scan once the archiving is finished and everything is fine.
This might be something easy to fix for McAfee users if we are pointed to the directory where the archives are created, as we could probably just prevent scanning of that location.
In anycase, it's an irritating problem, but not a show stopper. Either way, I figure it is something to add to the known issues list to help others out in the future.
