Shane, I haven't gotten around to using Malwarebytes but it seems that the rootkit virus(?) hasn't caused an issue. I haven't forgotten about it, though!
What I wanted to mention is that McAfee sent me a notice that my virus protection has expired. Apparently they're really feeling sorry for me because they've decreased the price of their software by $30 from what they were going to renew it at earlier!!! What a deal!!!! And BTW...it's Dell Recommended!!!!
Just thought I'd pass this very valuable information on to ya'll.
