Not sure what avast topics i might have been on before but tonight i left the computer for an hour or so on the avast web forum page then when i came back to the system the MBAM popup was there waiting for me, had no other links open anywhere so its got me stumped, just thought i would ask finally because i haven’t been able to work it out myself after studying this for quite a while now.
Other than that though iv never had it block anything legitimate that i know of and the ip blocking does seem to work quite well as it has stopped alot of nasty things, mainly things that are on pages rather than whole sites so i cant see myself disabling the ip blocking because i believe it does do what it is supposed to.

Thanks anyway David.
