I have purchased a new laptop 2 days ago. My brother was using it since I bought it. Now when I saw there was no antivirus installed in the computer . I thought of having one as my computer is now very much prone to viruses. i donít want my new laptop to get affected in any way. I want to know how is Norton Antivrus ? I have never used Norton antivirus before. my friends have Norton antivirus installed in their computers. can I install Norton antivirus in my laptop ?
