I will explain my situation.
I have an avast! antivirus, one of the newest versions.
No changes on my PC performance, everything works fine.
BUT, every time I turn my PC on, an avast! window opens! It shows me, that I have a virus in my computer, but that window is old-school! If I press Ignore, than it asks me, if I should restart my computer and run a scan. I press Yes, than it restarts and scans the whole computer. After the scan the same window pops up! There's an another button, too! Delete now. I press it, the same question pops up. If I press Yes, than it restarts and scans and pops up the same virus window!!! If I press No, then it does'nt restart, but the next time I turn on my PC, THAT WINDOW POPS UP AGAIN!!!!!!!! And if I search for that infected file manually, I can't find it! I search up the whole computer!
I don't know, is there an infected file somewhere, or why is that window popping up? Plz help me.
