Thanks. That seems to have taken care of the adware. If you want to remove the other policy restrictions, select all the bold text and press Ctrl + C to copy it, then run FRST and press Fix.
start::
HKU\S-1-5-21-3959293856-1355182806-1025034787-1001...\Policies\Explorer\DisallowRun: [1] Mshta.exe
HKU\S-1-5-21-3959293856-1355182806-1025034787-1001...\Policies\Explorer\DisallowRun: [2] powershell.exe
HKU\S-1-5-21-3959293856-1355182806-1025034787-1001...\Policies\Explorer\DisallowRun: [3] bitsadmin.exe
end::
To completely remove FRST, rename it uninstall.exe and run it. The computer will reboot to complete the removal.
If there's nothing else, it would be appreciated if you would mark the thread as answered, by pressing Yes below the post or posts that provided the solution.
Good luck!
