Rootkit - nemohu smazat

Avast mi našel hrozbu na této adrese:C:/Windows/system32/drivers/sptd.sys
I když dám vymazat, tento soubor zůstavá na svém místě, vymazat ručně se ho bojím abych něco neprovedl systému, mám Vista. Když tento soubor prověřím avastem samostatně je v pořádku, ale při testu se objeví výstraha na vir. Poradte prosím…
Díky libor12
