BUMP
Any news on this? Still affecting me. I will do a fresh install. The blue dot on the clock of the AVAST email scanner icon has been showing for the last 15 minutes. I forgot to switch off the outlook/email scanner. Seemed OK yesterday, but today, like last week, its goosed my machine. It will come back to life when the scan is complete, but whilst the scan is taking place, I cannot do anything elese on my machine - presumably only one virus scan can occur simultaneously and the outlook scan is locking out all the other scans? t may be of interest to note that both core 1 and core 2 are running negligible CPU - ie under 3%, RAM 27%. Wonder if its in an event flag wait? Looks to be an intermittent issue or possibly one that seems to affect only certain types of email messages - HTML, and scanning the forum, many odd queries of peoples machines running 4.8 running slow seem to be exhibiting the same/similar issues.
