Probably my worse is shockingly ESET. It was a giant resource hog, ever since the incident been sticking with Avast. Iobit and Mcaffe are pretty up their though...
I disagree. ESET was the best during 2009-2012. Smooth and great protection. Only signatures are not that strong these days.Still not a resource hog compared to AVG/Avira.
Strange, Eset products are assembly code based and for this, quite light on resources and I can confirm that due to my (limited) experience with Eset.
Well, I haven't had experience with any really bad AV's like some of you. Knowing what av's to avoid, I've never tried stuff like Iobit and ClamAV.
However, I had a pretty rough experience with ESET. I had it installed in my old mid-tier W7 laptop and the interface simply wouldn't work properly, it would block and take minutes to open some menus which was extremely frustrating. And that was in a laptop with a fresh W7 install.
Then, when I updated to Windows 10 (it was right after W10 got lauched), I lost my ESET license randomly. Since I had no proof of purchase or key to get it back, I uninstalled it and installed avira free. I still tried to contact ESET but if I remember correctly, many people had the same issue of lost key and my attempt to reach to them was ignored :/
