"Error 1606. could not access network location %appdata%/adobe/acrobat/PREFER~1/."

USING Windows 7 HOME BASIC

Error 1606

As for the virus, run a scan with free malwarebytes antimalware as well as the resident AV and let them clean whatever they want to.

Ok fixed. Using method, create new admin account and install it. the registry method kinda scary to edit it. Solve!
