For me it's ESET Internet Security. It's lightweight, unobstrusive and has no impact on the performance on my PC. Not to mention the detection rates that is Superb. I just wish it had a rollback feature and application control like Kaspersky.
Remember one thing there is nothing like "the best" in security field..each and every AV has pros and cons right from Avira to Zone alarm..If and If i need to say the "perfect Av" (i know that is inappropriate and false) it is only "KASPERSKY" ..that's it!I originally voted eset but I decided to switch to bitdefender because in my humble opinion it is the most robust and best rated suite at this time

The words spoken above are from my personal experience testing of more than 7 yrs+ with these AV Suites.
