I feel your pain.
I’ve used Trend for ages. Liked the fact it was quick, non bloated and simple. Not any more. It’s just as bad as Norton as far as being a hog. Once it runs out in Aug. I’m done with it!!
For the last month when Trend did a full scan, my system locked up solid. I found it will not play nice with Open Office. If I set it to not scan Open Office, it is fine . . .
