MarieW,
I will be both online and offline when my programs become Not Responding.
it says that I am online when I have these problems.
So which one is it? Online, offline, or both?
Give us your specs...OS, Antivirus Program, and any other programs you use to scan or prevent atacks including, but not limited to, anti- adware/spyware/malware/, and firewall.
If it only happens at your house, it may be necessary to request that your ISP change your IP address. I don't know if they can do this easily, or if at all as a request. Furthermore, I have no clue why a malicious prog would wait for connections from a server rather than the other way around, but I've been surprised before. Just provide us with your system's information, and we'll go from there.
