Windows Defender and Norton Internet Security whats the difference really.....as i stated in my earlier post no Single Anti virus program will give you total protection, you have to use some other variant of a virus cleener to offset some of the weakness that your main program will miss....

Take for example i once had Norton Corporate edition and AVG free non detected a Trojan i had on my pc until i installed Mcafee Enterprise.

Your right...but I don't think any combination will give you "TOTAL" protection either

I was just saying that this combination works best for me and maybe it might work for other users as well

@ mallard you must have had some experience with virus infection, Just like me, thats why we use the dual antivirus program, and you are right what work for you or me might not work for someone else..but it's worth a try, thats why we are here to give advised and can talk about what work and what does not....

I like to break fix and test system i am running a VMware machinne with 3 antivirus right now still no issue.Symantec Endpoint, Mcaffe enterprise and AVG free. plus AGV antispyware, spyware terminator and i throw everything at it, when one miss the other catch...

I agree with everybody here that it is not atall a good idea to install two antiviruses in one PC. Moreover Antivirus and Spyware removal tools are coming together now a days. So You should get a good Antivirus which will help you to fight against Virus and Spywares both. Some antivirus like Panda Antivirus will not be installed if you have other antivirus installed in your computer.

I will suggest you to remove all the antivirus from your Computer and install a Good Antivirus which is capable of protecting you from all the virus related threats.

I use Kaspersky antivirus. It takes less resource (CPU, RAM). It updates everyday. It is cheap, It can detect most of the recent threats. What else you need?

Wish you best of luck on choosing a good antivirus for your computer.

Don't use Norton internet security!
Most RAM draining application in existence!
Get AVG Internet security, much better and cheaper
I have had too many bad problems with Norton IS 2007. They have lost my trust.

I had bad experience with Norton. Now, I have much problem with Symantec EndPoint. It spend much of your RAM. I just tried AVG pro this few days, seems it works well.
I agree to use some antivirus, but I prefer to have one the best installed in my PC and the other just online scanner.

What I do is a try different Anti-virus and see how it works for me... Costs a lot, but its worth the protection...

I just think that if your really new to computers and internet all together. Then we shouldn't through stuff at them like like "Use two different anti-virus's and two different spy-ware's etc" Thats my point.... Not everybody knows a lot about computer in general... never mind using different combinations of anti-virus's...

Thats why I suggested getting a Suite...


---------------------------------------------------

The other thing I wanted to bring up is the difference between free antivirus's and buying anti-virus's.

I perfer to buy my anti-virus because I still believe the "You get what you pay for" Theory. To me it seems like you are you using a free anti-virus software its not going to give the same protection as one that you would buy...

Thats just my opinion...
