I am using Avast free, version 10.3.2225, Windows 7. Everything is up to date. In the past few days, when I download a file, I get an error message that reads: Cannot execute file C:\Program Files\Avast [full path] avastui.exe. Cause: the requested operation requires elevation." I do not know what this message means. I do not know why it just started to appear, and I have not been able to find answers here or elsewhere on the Internet. Any help you can provide is appreciated
