I cannot afford the $59.99 yearly subscription for anti-virus software, so what am I supposed to do?

You really, really need to just go online and download and install a free antivirus program. Check with your internet service provider (ISP) to see if they offer free versions of antivirus software along with your internet service. Most of the larger ISP’s do offer a free subscription just for using their internet services. If you login to your online account, check to see if there’s something called “Data Tools” and see If the antivirus software download link is there for you to install. If they do not offer that as part of your service, that does NOT mean that you do not install antivirus software. Not having antivirus software running on your computer is just asking for trouble and will most likely end up costing you money in the long run with repairs due to virus/malware infections and the like. There is an article by PC Magazine that lists the best free antivirus solutions for 2015 and they have 98 different packages available. Some offer more features than others. Some offer more ads than others. None the less, the link to the page is here, (http://www.pcmag.com/article2/0,2817,2388652,00.asp ) and you need to simply do some research and pick the one that you think will fit your needs best. I would recommend a product that also includes Malware scanning and removal. Lots of the antivirus programs out there offer this as a feature.
