Q: i already try the NORTON and AVG... i want the best anti virus to my computer...
A: The free versions of Norton and McAfee really don't do much to help you. If you want free virus protection, the best ones are in order Avast, AVG and Avira-with AVG the simplest to use and least taxing your your system. These free downloads can be found at Download.com on the right side under most popular downloads. Of these free anti-virus applications, Avast has a slight edge among users according to CNET reviews which most regard as unbias because it publishes its own reviews and those of users who have downloaded the program and physically used it. AVG is also excellent and Avira is new and seems to be gaining a following. All are rated higher or equal to most of the software that charges you. All are also rated higher than Norton or MacAfee that you must pay for. Statistically, of the pay for security software applications for windows, "Trend Micro" is rated the highest in satisfaction. That is the same rating as Avast. The benefit in using Trend Micro is that because it checks your computer running from it's own servers and not from software loaded onto your computer, there is virtually no additional load on your processor. In summary, if you want minimum interruption in downloads, Trend micro appears to be a way to go. The next best is ESET NOD32. If you can stand a little of the delay and want to save money, I recommend AVAST, Avira then AVG. One other thing I did before I got my Mac and still do on the XP side is create a separate partition on my hard drive just from downloads. By doing that, you can turn off you virus protection when you download whatever you want (to increase the speed of the download) to that section of your hard drive with fear any viruses you download would affect the rest of your hard drive. Once the download is complete, you can turn your virus protection back on and run it on that part of your hard drive. It works great and very quick, once you know you have a clean download, you then can move it anywhere you like. Although almost nobody does this, I highly recommend this for anyone doing a lot of downloading. Many of my friend use to ask for my help when they go viruses from downloading. They use to get viruses regularly, but once I helped them with the partitioning, and showed them the ropes, none of them call me for help anymore on this unless they make a mistake a miss a step. For what it's worth, I personally use Avast and occasionally a free version of Trend Micro. If ESET NOD32 were free I would be tempted to try it to replace Avast that is equally rated. I have provided links to assist you in showing the reviews and hope it helps. Good question and security minded pre-emptive. I wish you the best.
