Do i need norton anti-virus on my computor, if i have the windows defender downloaded?

Having them both is a good idea. Windows Defender is a spyware remover and blocker, while Norton Anti-Virus is a virus scanner and remover.

Windows Defender provides protection against spyware and popups, but not viruses. You should have an antivirus program installed in addition to Windows defender for proper protection of your PC.

no its a waist of money and has to be repurchased several times for updates
Yes, you still need an anti-virus program..Windows defender, is a spy-ware program..Windows, just released a new automatic program, that takes care of all your security needs..It has an anti-virus program, a spyware program, and many other features..Read about it here..I have it on my computer, now, for about two weeks, and I have not had any problems yet..It is still in (beta) testing mode..Good Luck.

You can never have enough anti virus's on a computer I run two on this one an if one miss's the other picks up.
anti virus programs are much alike in that they permit what they like even if you do not,ie spyware but regards anti virus,as long as its up to date not a problem but you must keep up to date to prevent new strains getting in ken
