I actually used to use:
Woolworths Internet Security
It cost me £5 a year and was constantly updated , it had a game mode and it wasnt at all gutsy in the processor department!
BUT YOU CAN'T GET IT FROM WOOLIES FOR £5 NOW so... I am sad
lol
anyway , you might still be able to get it from its producers though maybe not for £5 lol
The software was made by panda
