unwanted Pop up window
I updated my iMac to mac OS Catalina V 10.15.7 and when I open up Chrome I receive a pop up window advising me that "My computer is low on memory" and that I should close come applicatons to free up memory, but all I have open is my browser. I have computer experience and am not able to solve this problem malware.
