My mac has not been behaving properly so I cleared logs and cashes with disk cleaner pro. That did not work so I ran bit defender. Bit defender says I have 2 active threats but that the disinfect failed. I clicked on show in finder and was able to trash some of the files, then empty the trash. However, some files when I try to trash them it gives an error message saying the files could not be moved to trash because they are lock. So I click get info and the checkbox for locked is not checked. So why is it saying the files are locked when they are not and how do I get rid of these viruses? Thank you.
