Microsoft Security Essentials ( MSE ) : free program.

Note : After installing MSE, you will find that it has shut down Windows Defender. That is NORMAL. MSE has its own defender, and running 2 defenders will create conflicts as well as redundant.

Avaste free edition :

Just personal opinion of course. I use Avast , I have also got superantispyware and Malwarebytes. I recently changed to Comodo firewall which seems fine and I seem to boot up quicker. They are all free for personal use and I have had no trouble with Viruses Trojans Hackers etc. I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly.
