The ultimate question.  When I'm installing SolidWorks, should I turn off the anti-virus software?  SolidWorks Corp will tell you "NO!", but your VAR will tell you "YES!".  Where's the truth?  "It depends."

Some anti-virus software is smart enough to leave SW alone during an install.  However, many are not.  What underminds SolidWorks Corp's stance on leaving anti-virus software in place is the Knowledgebase itself.  It doesn't take long to find known problems that are attributed to having anti-virus software running during the installation.  I just recently did an install with SolidWorks 2010 2.1 with Symantec installed and running.  Guess what?  Issues!  I turned off the anti-virus software and repaired my solidworks install.  Guess what? Issued disappeared.

What are your experiences, one way or the other?
