trying currently ESS 7, light on ressources, no boot time added, stable as should be, had Avast IS paid version: quite reliable too, same as ESS 7, bad experience with AVG which is a ressource killer, cut down ethernet speed by 3(2 devolos), thinking of trying KIS next.
imo BDTS contains too much "sub" programs that are not related to antivirus and firewall, compared to BIS I'd call it bloatware because it sells you apps you can get for free, such as CCleaner to name one...
I was using avast! (which is second on the AV list) for quite some time, but as it happens it allowed ridiculous amount of viruses through, I don't even know how. I've heard from my service man that avast! was not to be trusted (although he keeps installing MSE everytime I have any computer serviced, so I don/t know if he's to be trusted), so now I'm using AVG, which after uninstalling AVG TuneUp (that installs itself automatically, gods know what for...) is not even that annoying if not for false positives it gives me once a week at least... I've heard that ESET was good and I'm surprised that it's so low on the list. I'm interested what others think, cuz I'm still looking for a perfect ativirus, if such exists
Hmm, I think most using MSE is because it's simple, supported and fairly efficient (performance wise). It's more like a lazy: You must have something at least. Usually you can avoid virus just being careful. The times I've been infected was because me taking deliberate risks, but I guess it depends on habits though. Currently I'm using Symantec Endpoint Protection on Windows 2012 R2 and I'm pretty happy with it.
I'm using avast free in my windows os, same as urie and yen, lightweight, have the auto sandbox so we can check the unknown application harmfull to our windows os or not.
I think Kaspersky is the of available options. Been using kaspersky Pure for more than a year, had absolutely no problems whatsoever !
