The latest build 5.58.7209 is the slowest I have ever had. Don't care for the new easy screen. Had trouble closing IE11, had to force close. Never had to do that before. It hung up for several minutes at 20%. Also, don't like the need to uncheck Avast. It is a pain to uninstall. I have never used Opera, but it wanted to process files. In all the years I have used CCleaner, this is my first issue.
