Ive just obtained a laptop for college. Its a used one. There are currently no antivirus software on the computer. The Hard drive is wiped clean. I'm in need of a good antivirus that's free, I googled it up but I honestly don't know of any good programs to use. Does anybody have any suggestions on some good software? If so what is your experience with said software? Pros and cons would also nice appreciated. Thank you!!
