I have tried 3 among them
1)ESET Smart security
2)Kaspersky internet security
3)Bitdefender internet security
Overall Features
Online banking is there in kaspersky and BD.
HIPS is there in Kasperky and ESET.
IDS is there in BD.
Social network protection is there in BD and eset.
Here Kaspersky scores than the other 2 because it has anti-banner and some other features.u can use adblock for antibanner !
Bitdefender has more or less same features to that of kaspersky...More features are available in total security
ESET does not have extra features sticking to its legendary antivirus and firewall...facebook protection is a new feature in version 6.
Overall Features=>Kaspersky>Bitdefender>ESET
Detection
Here Bitdefender is the run away winner

kaspersky comes second but just...But ESET somewhat lags behind but it doesn't matter because it is upto industry standards.
Detection=>Bitdefender>Kaspersky>ESET
Removal
All the 3 are good at removing what they detected..with some malwares kaspersky and eset required system restarts but I didn't find anything with BD.
One time ESET was unable to remove a adware although it detected it...It kept on downloading something...
Removal=>Bitdefender>=Kaspersky>ESET
HIPS
Kaspersky's HIPS is the best among the three:bravo:
BD does not have HIPS and ESET's HIPS must be trained to make it fully effective
HIPS=>Kaspersky>ESET
File Rating
Kasperky and ESET have file rating from the cloud but BD does not have this...Kaspersky's file rating is better than ESET
Cloud=>Kaspersky>ESET
I think BD uses cloud for URL scans and quick scans
User Interface
ESET-very simple
Kaspersky-attractive
Bitdefender-in between attrative and simple:lol:
I think attractive interface of kaspersky makes the users attracted to kaspersky!
RAM Usage & CPU Usage
I do not know about the correct figures
Some say ESET occupies more RAM..about 100 MB of RAM but it does not feel heavy on the system at all
At the time of typing this all services of BD occupied only 20 MB of RAM! but I feel that it is still heavier than ESET
About Kaspersky...Heaviest I used in my lifetime...It will take minutes to startup and during full you can turn off the display and sleep...You can't do anything while a full scan is run!
Usage=>ESET<BIitdefender<<<<<Kaspersky
Support
If one make a complaint with the support all the 3 will respond within a day!
Kaspersky's forums are very active compared to other 2.
ESET's forums ->inactive
BD's forums->very inactive [only one moderator is there to moderate the entire forum and he will not reply to every posts:dodgy

BD compensates this with their
live chat support which is available 24*7 and they are really helpful:fan_1:
Overall
Kaspersky is
very heavy.use only in latest systems with high configurations..
BD was
buggy...but now miraculously all problems are solved:exclamation:
ESET has slightly less detection rates but
system friendly...
I can't vote in the poll because I have not tried others...
Among the three
I will go with BD (lighter and with best detection rates)
Can someone from the testing and reviews group test these 3 for proactive detection and zero day threats detection and removal??
