You should only ever have one anti virus product running. Two or more will conflict with each other and slow the machine almost to a standstill.

I believe Microsoft Security Essentials has replaced Windows defender may be you should consider removing defender and installing Security Essentials.

Also remember no anti virus gives 100% protection. You need to use common sense. Never follow links in emails even from friends unless you have specifically requested them. Don't allow anything to install on your machine unless you have specifically chosen to install it.

Your computer is probably slow because there are too many unnecessary programmes running in the background. Apple, Adobe and most printer manufacturers are the biggest culprits.

If you haven't got your browser set to never retain history or never close you browser then you will have a large amount of unnecessary temporary internet files clogging you hard drive.

Run a disc cleanup and also de-fragment using something like defraggler rather than the windows defragmentor.

If you install MSE it should disable Defender automatically.

Have a look here for checking your memory options. There is either a tool to scan, or you can use the dropdown menus to find your model. More memory is always great, but clearing out unwanted programs is almost as good.

No need to buy the memory from here,ut it is an easy way of identifying what you have and what options you have.
