Hi, Stellarman,
I bought Avast Cleanup in May 2018, and after I inadvertently removed the desktop shortcut last month it stopped working. It has disappeared from the main list of programs and though it still appears on the add/remove list, I can't open it from there.
I thought it might work to download from the link you give, but I get a message: 'This app cannot be executed on your PC. Please contact the editor of the program'. I am on a HP PC, W10.
What do you suggest?
