am now trying the things suggested and will post what I get. all in safe mode. firstly have installed TDS, updated the database before running and then attempted to scan. An option popped up while/when about to scan and without thinking I said yes - scan seemed to start but then program shut. now wont run - program closes while doing initial memory scan.
Microsoft antispyware is running in the background and asking if I wish to allow TDS shell extension in c:\windows\system32\tds3shl.dll - should I allow or block?
