Where I work McAfee On Access scan is enforced to be on for all our machines.

Visual Studio 2010 isn't exactly the speediest program at times but combining a large website, several build configurations and mercurial repository files in a project folder results in a very large number of small files, many of which get scanned when being read or written.

I'd like to try and ask our IT department to add some exceptions to help speed VS up but that will likely not be an easy task. What recommendations do you have for the minimum list of exclusions I could give that would give the most noticable improvements?

We tell everyone to pick a project "root" and exclude everything from that folder.

Real killer is probably the .hg folder if you need to settle for a global switch; that is the really unique to development thing that is typically the problem.

We had a similar issue with Eclipse and solved it by excluding .java and .class files. I would assume adding their equivalents for your language(s) would be a good start.

Also worth remembering you can compromise on any list you come up with, in that they can be scanned when written, but not during read. You still see a performance boost.

I would ask this question on the McAfee Communities VirusScan Enterprise forum, the guys there can give you the best answer in my opinion.
