Spy Sherif - How do i remove all of it?

[Trox]

Dad got this Spy Sherif thing installed on his PC, totally screwing it over runs scans on start up ect, thing is he said it only started doing this after he logged out of his banking account :/

Not knowing much about it i done a google and found this site with a removal tool...

Now i dont know anything about this... How trustworthy is this site? I just dont want to end up making it worse than it already is.
Also read that a format will be better? omg :/

Gonna go along this afternoon to check it out, any help before i go is appreciated

In the end i gave in, nothing was working i formated. If i done that from the start i woulda saved a lot of time
