Rushing out half-baked products
My company is in the process of switching from a stale old, slow, version of Norton AntiVirus to the Symantec Endpoint Protection. With NAV I went 3+ years on XP Pro without seeing a single BSOD. Now I get them all of the time! Turns out that we're already 4+ maintenance releases back. The release notes for critical crashes corrected in their maint releases are a mile long. My machine would BSOD the instant I unplugged the ethernet cable; A coworker had it BSOD when he attempted to save a document to a flash-key. (search for Symantec Endpoint Protection bluescreen)
Unless you want the headache I'd hold off for now. Just underscores the need to wait for service pack 2, or whatever the equivalent is in the virus bloatware realm.
