Hi Robert,
interesting question, I must to admit.
I have few theory about this and if you want (and have free time), maybe we could together investigate this?
As I know, the most common methods of infection are: 1. through outdated versions of the Sun
Java platform
2. manual installation or installation as a component of another program
So Robert check this things:1. Check configuration of your Norton AutoProtection, did you Turn On protection from PUP (Potential Unwanted Program, adware/spyware/dialer ...) or your autoprotection only work for hard infections like viruses, trojans, worms.
2. Check is it your JAVA Up to date (Control Panel ...)
3. Think about possibility that you by your self install infection as a component of some other program
4. Do you have firewall, by the way ?
I'll think about this more tomorrow night.
P.S.So sorry if I make to much grammatic mistakes, you know that my English isn't quite good.
One more things, I hope that you know that we open competiton for Moderators at SCforum? What do you think about that position?
I was move this Topic to Help Center since we clean other boards from outdated posts etc.
