Yep, that's what I always do, Corrine! It's quite funny, the OP's end up keeping and preferring MSE over whatever they were using before.
I don't impose my opinion because I don't know enough about anti viruses to go into specifics. I just know some 3rd party anti viruses cause issues with the NETBIOS ports, and can be a leading cause in BSOD's depending on the bugcheck, etc. If I have reason to believe it's the case, or a contributing factor, that's when I will recommend temporary removal and replacement for troubleshooting purposes.
