Zoner is the best.
kaspersky was using 100% cpu when scanning, and slowed my computer down too much in general so i just removed it
AFTER scanning the file system the AVG Free scanner process was using 465 MB. So much for “light memory usage”.
I think Panda antivirus is the lightest and with the simplist interface…
