So I wake up this morning and I go to check my email to see if I have to go to work and when I click on Outlook, an error message comes up saying it can't find the .exe in the system directory. I tried opening trillian, same thing. Then I tried to run AVG and it couldn't find that either. I finally got thru by right clicking on the C:\ and telling it to scan with AVG. It did and found a trojan optix and cleaned it. But my programs still don't work. And I can't even run system restore to fix my OS. Is the only way out, to reformat? Or is this a virus that can be quarantined and fixed?
