For a long time I ran Norton's virus protection. It became very expensive with multiple computers, so switched to kapensky. That one let me down, so I went to Mcafee. When that one expired, my computer kept loosing it's Internet connection. I kept getting warnings about being at risk asking for renewal. I had installed the free Microsoft protection. I cleared Mcafee right out of my computer and I no longer have Internet connection issues. Does anyone else have the free Microsoft antivirus program and does it seem adequate?
