Was this the article you read? KB01062 - Anti-virus Software and the PI System
I haven't seen any complaints about that version of anti-virus specifically. As long as you can exclude files/directories with it, I don't think it should be an issue. If possible, I would recommend testing it on a non-production environment first though.
You can create a real mess (including data loss) if your queues or primary archive get quarantined. It's something to consider.
Please also consider protecting your PI System with application whitelisting.
