Hi Todd,
There are cases where the virus software is scanning things it should not
(such as the logs, databases, M drive etc.) and can cause serious problems.
The aforementioned should be excluded in the virus software.
To see if AV is the issue, disabling ALL the AV services (and turning of
background scanning in the registry) then rebooting will usually give
positive results. Below are some articles to check out:
