Browsers are still S L O W!!!!!!!
After reading some of the solutions for slowed browsing after updating my Mac Book to Catalina I uninstalled the TrendMicro software and installed the latest version, 10.0.1686, follwing the instructions provided in the TM responses to previous posts. Unfortunately this did NOT solve my issue. Any browser that I use is interminably slow. And it is definitely the TM software. If I shut down the software browsing speed is substantially faster. I have been a customer for many years and this is the first time that TM software has caused system issues. Unfortunately if I can't resolve this soon I am going to have to abandon TM and move to a different antivirus solution.
