that whole paragraph, "if you are running into a stubborn trojan"....had no meaning for me....what are drivers? formats? all this stuff is greek to me. I have no frame of reference..... when i said compudodo, I meant that dodo part.... the reason they are extinct is that they were incredibly dumb dumb dumb...... honestly.... i just don't get the whole computer scenario, how it works, the terminology..... i'm patching things up as I run into them, it's the best I can do. i'm sorry.
ok... basically if you have an infection that even the pro's on this site cannot eradicate, (usually a rootkit, which there is no way to tell if it's actually fully gone or not except using linux, but we will not go there.) the only way to be sure is to do a full format. (erase your hard drive) and reinstall windows all over again, provided you have your drivers (files required to get your hardware working correctly with the operating system) Considering your experience, I would have someone personally LOOK at your PC (not just stand there and look in it's direction, but get on there and try to find out where and what the problem is then tell you in a way that you can understand.)
I would NOT suggest anything like GeekSquad. read ripoffreport.com on geeksquad and you'll find out why. Considering you are on these forums asking for help means you have the ambition to learn how to fix. or possibly prevent the problems from happening, granted though, it is a lengthy process to understand the concepts involved when dealing with this type of technology, it is designed to hide from you, so "digging into the registry" may seem like 40,000,000,000 piece puzzle that you don't want to even start, it is inevitable.
To sum it all up, see if you can do (as everyone else above have said) without dishing out the cash.
