surprising i have to agree with DieselMan. you might not experience a conflict, but you will be much more prone to a conflict when operating 2 security software with a similar function since both are hooking the same areas of the system, and ther is a chance during a detection that problems could arise, such as BSOD's sometimes.
just like when running more than 1 AV, u might not experience a problem right away, but eventually and under the right circumstances its much more possible.
you people are taking the same stance that oil drillers seem to take, you dont notice any immediate downsides so you continue as is thinking what your doing can never be a problem, then when a problem occurs under the right circumstance, you end up with serious problems.
its better to be aware of the potential problems instead of thinking its all fine and dandy
