51949 - Weird interaction with McAfee antivirus spikes CPU usage

Status: VERIFIED WORKSFORME

(Core :: Networking: Cache, defect, P3)

Description

[rhomolka]

NT4 Service Pack 4.
Mozilla talkback M17
McAfee VirusScan 4.02
Strange.  When I surf some sites (Slashdot being one) my CPU load goes sky high.  
Weird thing is, the load comes from McAfee VirusScan, which jumps to 99% CPU.  
When I kill Mozilla, the load goes down.

If anyone wants me to do something on my box, I'd be open for it.  This is 
strange and I'd liek to know what's happening.

I see this too on my NT4 SP6 system.  usually related to cache activity?
Whenever it happens, I temporarily disable the virus scanner until moz has
finished playing with the cache.  I've wondered if the lack of filename
extensions on files in the cache has anything to do with this, but can't find
anything in the mcafee help about special treatment of extension-less files.

--> networking cache, on the assumptions of users (and logical, as virus
scanners would check the cache)

Confirming based on two sightings.

I've haven't seen this behavior in quite awhile (at least 2 weeks). WFM now.

Has anyone seen this happening recently, or can we close this bug?

VERIFIED/WFM:
I haven't heard any complaints of this at work (we use this).

I'm going to reopen if I have problems after loading my systems w/ the latest
version and scanning.
