Executed avastclear, says successfully, but still no joy:
WU -> error 000000B7
manual -> error 80070002.
Just wondering...
on C:\ there are dozens of those folders whose names are a string of hex digits, and some of them contain sp* files, like spinstall.exe or spwizui.dll.
Could the issue have anything to do with them? Anyway, are they safe to delete?
Thanks
