Hello:
Three years old? Lol, my pc was from 2001 (and replaced only a couple of months ago)

.
Well, let's just hope the problem will be now solved for good. Anit-spyware programs are good and cause no problems, I can say that myself too. I know Norton is very good too... you should be safe now, but remember also to constantly updating and scanning your system

.
I hope you'll be back soon Noname.
