    We have a mid 2007 iMac. We have about 150GB free and running snow leopard.

    It's very slow and we're trying to boost it's performance. It has 3GB ram.

    I was thinking of getting el capitan as we want updates anti virus support.

    Do you recommend getting el capitan and if you don't, what is the best free anti virus for snow leopard?

    and what can we do to boost performance without having to spend money?

    I'm afraid the only way to have a performance boost is by installing an internal SSD, what seems to be not so easy.

    Or you could connect it with an adapter to the Firewire 800 port, it's at least faster than USB 2.0, but you will not get near the full SSD speed since it is much slower than USB 3.0 or even Thunderbolt. But it may be a little faster than the internal HDD.

    It seems your iMac has a 1 GB and a 2 GB RAM module installed. You could upgrade it to 6 GB maximum by just replacing the 1 GB with a 4 GB of the same type.

    El Capitan will not speed it up, but it might also not slow it down. You could try it on a second partition.

    I gave an early 2008 MacBook Pro to my Mum, it has just 4 MB and a HDD. El Capitan takes long to boot (don't know if SL would be faster), but after that it seems pretty good usable if you don't open too many applications at the same time and use it just for simple things.

    I'd opt for an SSD and if you install an antivirus application that will degrade your performance even further. There's really nothing you can do about improving performance without spending money.
