I know McAfee has had a bad press but honestly it's the only antivirus that plays nice with software I had needed for businesses like sage. The company I work for also uses it, which makes me think that it can't be that bad!!
I am right there with you. I tried one of the newer builds not too long ago and it still sucks. Intel bought this product and thinks it's going to make money with it? in my mind it needs to be torn down and rebuilt from the bottom up.
Security is all in the mind my friend, it's all in the mind. Just because your company uses it doesn't make it good, it just means your IT people are not paying attention.
