The following link will take you to downloads.com
to the free anti virus section where you can download a program for free until you are able to purchase one that you want. You can further refine your search by selecting what operating system you are currently running by clicking on the one you have in the box to your left of the screen. The following are a few good ones that I have personally used in the past and had no problems with AVG, Avast, Avira, but you can read through the choices and find one that you would like.
Some things you want to look for in a good anti virus program are: A resident shield (which is a active protective scanner that runs all the time by scanning things like web pages, other running programs, etc). A boot sector scanner or capability (some anti virus programs do not always automatically scan this section of the hard drive). If your system does not have a firewall, you can find some anti virus programs that have a built in firewall. Some programs will also have the capability of scanning your emails or help you fight Malware. These are just a few suggestions when searching for an anti virus program.
When you find one that you want, ensure that it will be compatible with your system by reading the "system requirements" and also read the "user ratings" on the site as this will give you a good idea of any problems people may have experienced with the product.
Some key things that will help keep your system safe: 1. Never open any emails that you do not know who they came from, especially ones that have attachments such as pictures, videos, executable programs (which will have the .exe extension at the end of it). 2. When you download something, never open it until you have first scanned it whit your anti virus program. 3. If you keep personal information on your system such as banking information, personal information like social security numbers, addresses, names, phone numbers, business information, etc you might also consider using a good encryption program as an added security measure. 4. Use a firewall program on your system as this will monitor your computer ports and help prevent someone from gaining access through them to your system. 5. If you do not have your computer password protected you might also want to consider doing this (in case your computer system is stolen, criminals will not have easy access). 5. When creating passwords, make sure you use a combination of letters and numbers and try and make them at least 10-14 characters long on anything you password protect. 6. Never leave the password near your computer or where it is easily found (again in case your system is ever stolen).
All the things I have mentioned you can also find on download.com for free. I hope you find this information helpful and is useful in solving any issues you may have. If you need further assistance please feel free to ask. I wish you all the best
