Virus

This is Kerry.  I am having problems with my computer.  We think it may be a virus, but who knows?  It has made it so my computer is very slow and crashes or shuts down frequently.  Braden tried restoring it from 2 days before it started acting up, but that didn't work.  Any suggestions from people who know computers would be much appreciated.  In the meantime, I can't really use my computer, so if you have written me an email and not heard back, I've not been able to get on Braden's laptop to check it.  Braden is to sharing his laptop as Kerry is to sharing her computer, so...I will not be on the internet a ton until we get this thing figured out.  At least that's what I'm telling Braden.  ;)
