As per everyone, avast went nuts on me last night w/ Delf-MZG messages. Unfortunately, I have the habit of selecting "delete files" (as opposed to quarantine). I haven't seen any effects yet. Perhaps the files couldn't be deleted because they were of running apps. However, I'm afraid that, as happens with windows system files, the next time I reboot all those files will be deleted.
So how can I find out what's been or will be (upon reboot) deleted and better yet, of course, stop/reverse it. I figure, even if I can't stop if perhaps I can at least repair the damage after the next reboot if I can figure out what files to restore.
