can't delete rootkit MBR:\\.\PHYSICALDRIVE0

Avast has started flagging the rootkit MBR:\.\PHYSICALDRIVE0 as well as the trojan alureon every 5-10 minutes but it won’t delete it, I ran a full system scan and deleted everything it found then ran a boot time scan and that said it had got it as well, but as soon as I signed in I started getting notifications that a program was trying to access an unsafe URL, is there anything I can do? I ran aswMBR, this is the log it returned:
