This part is especially confusing me: "Roxio. The GoBack software allows allows you to revert your Windows configuration file (the registry) back to it's previous states in the event of non-ciritcal errors. This program should not be terminated unless suspected to be causing problems." What do you mean?
What I am saying is if your system is infected and you make a backup copy you will aslo copy the infected file.
This is also the same with windows restore if the system is infected the backup will also be infected.
Also, what kind of thing would cause a problem that would affect my internet connection and one other person's that I correspond with, but no one else who I talk to?
If one of the people that you talk to is infected your aol may be blocking the infection, if you are not having any problem's taking to other user's don't that ring any alarmbell's to you.
All of this is really frustrating me, not knowing more about it; I'd really appreciate a better explanation. (About the www.dcsresearch.com hosts thing.
