I reloaded IE and the popup keeps comming that says I have a virus?

I did a dumb thing by opening an email that I was not familiar with. Duh....Oh well, now I uninstalled IE and the popup stopped when I use flock or netscape navigatou. I need to use the IE because i am in an online class and it only operates with IE. What to do What to do? Halp Hep Haplesss me plz?

The popup says: System Error you have and unknown trojan, bla bla bla click on click button to fix problem.and download a virus I did not do this and downloaded Spybot after Norton did not recognize it. Spybot did not find the vurus either and I do not know how to find the popup to disable it. The popup blocker does not stop it either I have three popup stoppers and nothing can stop the window from appearing every time I click or move the mouse. Odeah...what to do?

Its not a virus, its not spyware, its more of a trojan thats highjacked your browser, dont worry it not damage your computer buts it is very annoying. Panda Internet Security 2008 will remove the adware..but..it will uninstall Norton when downloading it (30 day trial)
