Malwarebytes premium trial Version 4.2.1.89 update package version 1.0.31228 Component package version 1.0.1061
Had problems installing free Malwarebytes, so I installed premium trial. Ran scan and had all issues quarantined. Result was a generally faster PC. But there are 2 main issues.
1. All MS docs (Word, Excel, Powerpoint) ending is x (docx, pptx, xlsx) open fine. All without x (.doc, .ppt, .xls) open in compatability mode. This did not happen until the Malwarebytes scan/quarantine. Will this cause me problems? Can I get the non-x docs to work without the compatability mode warning?
2. Microsoft Edge is extremely slow. IE works fine. Chrome works fine. I usually use Edge. It is set as my default. I'd like to fix it.
These are the main issues. There are others that come and go: mostly slowness to initiate a process for the first time.
What should be my next step?
