Jak zrušit služby?

V logu hijackthis se mi opakovaně, po odstranění služeb ty samé objeví opět.
Jak je možné se jich zbavit nadobro?
Hlavně se jedná o tuneup ut., nebo různé google updatery, nebo bonjour services...
Ovládá se to ještě odjinud?
Dá se někde najít seznam služeb, které nejsou nutné pro chod systému?
díky za radu
Petr
