Everyone tells me that the transmissions that are coming thru my computer are "normal" or "just kiddies messing around" or a "virus" but the truth is I've been hacked. My computer's OEM is Windows 98, I'm now running XP Home with Zone Alarm Pro and the latest McAfee Anti-virus. However, I have been unable to do a "clean install" and despite messages that my "old version of Windows will be eliminated" I have Windows 95, Windows 98, and Windows NT/2000 as options in my Setup when I boot the computer. Additionally, there is a "network boot" in my setup boot options. Inasmuch as I have never installed 95, NT or 2000 on this computer, how did they get there? Can I get rid of them? I know that XP contains some files for NT, but its the other OS's that bother me. Additionally, I am being "hit" from all over the world, and files change/add everytime I'm online despite the firewall. Does this website have any port control software I can download? Lot's of questions, I know. But I'm a dumb (former) blond!!! Help please.
