ESET Nod32 Antivirus is paid security, any particular reason to compare against a free Antivirus? Are you willing to accept other Free or Paid Security?
On my machine panda is lighter. i noticed fps drops in gaming while i tested eset. with panda there was no slowdown. but everyone have other systems and the products behave other for each one. i would trial both and than u know what is the best for u. but make a system restore point or something similar so that no leftovers from one av is there. that can slow down the machine too.
I have tested both and Panda, despite the fact that it is cloud based, it is a bit heavy.
Eset, thanks to the excellent code implementation, earn my choice.
