Something a little different this time- when I scanned my home directory, it only found a few (mostly archives) that it couldn't scan because avast says they're corrupted. Which they aren't- I opened them ages ago- but no more listings of lots of files. Still get the same error message when I right-click. At least now it seems to scan normally.
When I do a full system scan, it won't scan root, sys, proc, and some devices with various error messages: device doesn't exist-permission denied-I assume from what I've read this is normal on a normal system? Still the same when I right-click on any of these files. If it's working otherwise, I'll just settle for this. Not too many others use my machine, anyway, and if avast can scan my directory now, then that's ok. At least if they do something hazardous, I can find it.
I assume this means avast is scanning my home for viruses, and it's working okay?
