My favorite antivirus is bitdefender, however that is software that needs to be purchased. In my opinion the best free antivirus programs are Avast, and AVG. Try one of those and see if that helps.

Put aside all of the suggestions, and check here first: AV Comparatives. These guys test antivirus programs from many angles and give valid results.
Plus, all of the antivirus software companies offer you to test their products without paying for them, 30 days in most cases.
Going further, there are a few pretty good free options out there as well.
Finally, even with having antivirus installed, you have to watch your own moves while on the net.
