Comodo is quite good if it doesn't give you troubles with CPU or disk usage.
Kaspersky is not fully cloud.
SecureAPlus is free for the first year only.
You can also consider Immunet.
Panda is very light, but not so effective. You can couple it with NVT OSArmor
Immunet, but you need to pair it with something else.Comodo also is very light and standalone. Kaspersky is an excellent choice but when i tried it to my system is far from lightweight.
