387957 - McShield 99% of CPU when read/send new email or changing folders

Status: RESOLVED INCOMPLETE

(Thunderbird :: Message Compose Window, defect)

Description

[Jerry Klink]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1)
Build Identifier: 2.0.0.4

I was demo-ing Thunderbird 2.0.0.4 as an alternative to Outlook. I'm VERY impressed with one exception. Our company uses McAfee 8.0 Enterprise on all PC's, the settings are locked I can't change them.  One every new email, or send or even changing to a different folder, McShield sky-rockets to 99% and stays there for 7-20 secs rendering my PC unusable.  As much as i like the software, I can't use it in that present state. A friend has advised that i try the older 1.5.0.12 ver as a workaround. I can report that so far I don't seem to notice the same issues. I'm not sure what may have changed between the two versions, if that can be fixed and i can maintain the A/V scan of each e-mail, I can upgrade to the newer 2.0.0.4 ver. If not, I'm forced back to Outlook.

Reproducible: Always

Steps to Reproduce:
1. Try and open a new email in ver 2.0.0.4
2. Try and send an new or reply to an email in ver 2.0.0.4
3. Change to a different folder (all email moved by filters from inbox to a specified folder - inbox always left empty)
Actual Results:  
As described above

Expected Results:  
I can see/understand a temp slowdown as new emails are being scanned on receipt, but not why emails would need re-scanning when switching from one folder to another

Changed the view from folder one to folder two without the slowdowns / freeze
