What do you mean by "appears on any window"?suddenly Script error appears on any window & is impossible to delete.
Where did I go wrong & how to get rid of it please?
Sorry, I meant by "everything", all shown in the Disk Cleanup window. Those are not your personal files but temporary files and files that are not needed by the system. Disk Cleanup also cleans the cache of the Internet Explorer/Edge browser.I do not want to clean my HD indiscreminately, I may loose things I want.
Just to make sure I understand the problem:Thanx both,
1. No only on internet
2. Never OLARK??, and do not remember if downloaded any.
