Ever since my PC was hit by a virus, AE CS6 has been acting weird. I managed to cure the infection and I now have no issues with any other software. Reinstalling hasn't fixed this nor has updating.
Any time I do anything and I mean anything, in AE, the program freezes up. I have video of it I can share if helpful. The cursor spins, the screen flickers and I can only stop it by leaving the screen (hitting the Windows button twice). Once every five or so times this won't happen and I can actually get some work done.
What did you update? OS? AE? Both?
Usually, after being hit with a serious virus, it's just better to wipe the computer and start from scratch. Virus cleanup often messes with things deep within registries, drivers, etc.
Speaking of drivers, what GPU do you have and what is the version number of the driver you're running?
I updated AE 6 but am still running pre-10 Windows. Not sure on the specs since I'm at work, but wiping would be too much of a hassle. I bought a second PC which I'll use strictly for editing and hopefully that should resolve it. Thx
