I have windows 7; had it for years. Have updated Outlook.
A few weeks ago when I pressed "empty" on my recycle bin , pictured on the desktop, I got this "don't have this app. " I have open CCleaner as a choice on the recycle icon. Have had CCleaner several years, configured the same way as always. CCleaner opens, and runs fine. The other choice on recycle bin is a blank file located at the top of choices, just says "open" . It collects the deleted items, and I can delete then one at a time. As mentioned, "empty" just loads the "No App." I have run multiple virus-and malware programs you mention. Combo fix didn't help, but did manage to NEVER print what it found; 30 minutes is all I was prepared to spend. Have used it successfully in the past. It worked along until the notice that it is going to list what it found. Then it took a nap, I guess.
If this is something different, I can submit it again. The icon for Desktop is gone from the "where do you want to download this program. Now I have to use RUN. There used to be a Desktop icon on the left side of the page mixed in with several other things. Now that icon is gone as well
After fooling with this ( these icons) I bought a full version of MacAfee. I went through the settings and unchecked any that I thought might delete something needed. It took awhile to scan, but it found no virus, but did find what they call junk Don't know what it is, but the speed of the computer noticeably improved " App on recycle bin still missing I have used updated Malware bytes, Superantispyware. The desktop icon still refuses to show in either the left column, or the where do you want to download Used driver updaters-nothing.
Sorry this is so long. Was trying to help with details. I'm 70 years old which may be the problem.
