I should have known better but when I reported here I did not do an Avast scan on my external drive because I only turn it on towards the end of the day when I move files to that drive. It is an older drive I put in an external case, so there are lots of old things on there. I scanned a couple of other computers that did turn up something, but I won't go into those until I have this one squared away. My point on this reply is, can I just scan the external drive and skip the doing the primary drive? Advise please.
