[Full-Disclosure] Mcafee VSO (Virus scanner)

["gregh" <chows@xxxxxxxxxxxxxx>]

Problem:
--------

Approximately 2 weeks ago from this date (Sept 2), Mcafee put their VSO version 
scanner through a major update. Included in that update was the ability for VSO 
to do more for mail scanning than it previously used to do. It now has the 
ability to watch email come in via contacting the mail server at the same time 
as, say OE if that is your email program of choice. In doing so, it causes 
time-out errors which result in, depending on the amount of email you are 
receiving, either the email list not able to be downloaded without continual 
attempts or, as is also common, the entire email waiting being downloaded and 
then cutting off OE from telling the server to delete the email picked up. The 
result of that is obviously that you will get duplicated, or more, email.

Though Mcafee add the option to disallow Email scanning by removing ticks in 
those spots, it has no effect on stopping this problem happening.

Reported as a problem:
-----------------------

Approximately Aug 26th through their online reporting function. To date, no 
response.

Workaround:
-------------

Fortunately, you need only block, even with a simple software firewall such as 
Zone Alarm, "Mcafee Virusscan Email Module" from contacting Internet and it 
completely overcomes the abovementioned problem. 

Of interesting note is that the module actually shows itself to be part of a 
Mcafee virus scanning program that is much older than VSO and has no part in it 
of which I am aware yet it actually IS part of VSO, having been installed with 
the recent update of approximately 2 weeks ago.
