Yh ive had some bad browser hi-jackers just ask chris lmao..... the worst ones tend to be the ones the select the size of your screen and load up there site along with a pop-up on your desktop saying download this now..... that bugged the crap out of me , its pretty hard to get shot of them unless you have some suberb virus program otherwise i just reformated my computer , its impossbile to say wether a infection like that is ever truley gone thats why i think this person should re-format whos knows it could be worse than a hijacker .
If im not mistaken if you try and get shot of nero with this dll error it wont allow you to , im 99.9% this person has a virus....
