I have noticed alot of talk about norton adaware mcafee and even pccillen mucking around with spybot and my view is that some of them are just bad configuration or poor management on the users part
norton by many technicians hes been classed as a mediocer product
mcafee Ive heard alot of complaints of its misbehaviour
and adaware Ive read reports of it conflicting with spybot
but as far as im concerned it all comes down to how you set it up
because of all the increased malware spyware and adware attacks by hackers and non trusted companies anti virus companies have tried to catch up by introducing what you might call silent scanning to detect what they think is malisious software to keep one step ahead some have even introduced regestry control into their products to have better comtrol against hackers
if i get a product like adaware conflicting with my other security programs like spybot search and destroy and teatimer I configure them until I get no more conflicts and when I had norton the program did conflict but was soon rectified by changing settings
I now run bit defender and it cooperates with spybot better than ive seen any product and as a strange coincident I know someone else who runs avg
pccillen adaware and spybot sandd and not a single trouble
..
basicly it all comesdown to this every security program wants complete control to do the job it was designed for but not all parts of the programs work as good as others by putting the one you want on to run the main components first and configuring the other programs around them their should not be a problem in the world even if the program says so because you have to configure them around them and tell the program to ignore or standby sincronise around eachother or just disable theparts that dont work for you
