Just a quick hello to everyone, and a thanks for information already found. I had an experience with a Symantec notification today while working, so found this site while googling the threat name. Looks like it's controlled after a few hours of work. (fingers crossed!)
I have some background with 'puters (started with Honeywell mainframe systems a "few" years back") but am not anything approaching an expert techie, so I do appreciate folks who are willing to share their expertise and experience.
