>Thanks for that, Tracy, but, as I said, I threw everything that I could/had been recommended/etc at the problem and now I get my Windows and AVG updates and all is up-to-date protection-wise. At the end of "chemotherapy" I gave the m/c it did a MARATHON Windows security update, lasting hours - feasting on all the updates it had missed during the illness. I don't see how the above can explain the thrashing.

>The point is that it seems to have come out of all this slow and useless. It's like it could have turned absolutely paranoid and EVERYTHING is being constantly checked, as if, say, more than one virus checker is going all the time. But I only have AVG active. Again, there seems to be a proliferation of AVG background processes going on (whereas there used to be just the resident shield and temporarily teh AVG updater)

Something I'd probably try - just to see what, if anything, AVG might have to do with the issue, you might try decoupling from the internet, disable AVG and reboot. If your pc then operates ok, you might want to uninstall AVG and then reinstall it.
