Yes, you need to renew your virus protection every year
I was talking with a relative over the weekend. I had helped them build their computer several years ago. I mentioned that I had to renew my anti-virus protection. She asked why. I explained that new viruses are being created all the time so you need to keep a current andi virus program on your PC. She was working with the same virus protection program I put on her PC years ago. Luckily she didn’t have any viruses on her PC - which we found out when we purchased a new anti virus subscription!
