Condobloke and DC3;
Thank you for the replies.
Condobloke - Yes Windows Repair did didcreate a restor point.
DC3 - Yes did boot into save mode and used last good configeration to recover.
Again thanks for the replies.
Got into this mess by attempting to use a few of MALWAREBYTES diagnostic tools.
Attempts failed with a message the tools were not 32 or 64 bit programs.
Sent an email to Malwarebytes and their tech support responded with a couple of scans.
The scan were negative according to MB tech support..
However, Malwarebytes Anti-Rootkit mbar-1.07.0.1012.exe still gets ".....is not a valid Win32 application"
I also get the "...version of the file is not compatable with system....x86 or x64....".
MB tech support suggested Windows Repair ( all in one ) by Tweaking.com.
As written above - did the diableing out of sequence and so did not get a "Clean Boot".
FIRST - updating my backups and system repair disk.
Still have a problem - I think ??????
any thoughts on what direction to take ?
