Hello Kevin, and welcome to Seven Forums.
If able, see if downloading and merging the exe
(LNK) options in the tutorial below may be able to help. Afterwards, be sure to do a full scan of your system with MalwareBytes
Default File Type Associations - Restore
I would also recommend to use Windows Defender Offline
to do a full scan your system at boot with. If necessary, you could create the bootable 64-bit USB/DVD on another computer to use on yours.
Hope this helps,
