Hey there, try going to software programs catalogs like
Softonic http://www.softonic.com/
SoftwarePuppy http://softwarepuppy.com/
Over there you can just type in antivirus and you will see all the matching results.

Try one of those:
free.avg.com (dedicated part of the site for the free version)
avast.com (chose the free version)
avira.com (chose the free version)
All 3 offers a free version of their antivirus. All 3 free offerings are excellents.
The free versions are intended for personal use at home. At work, you are asked to get the paid version.
