the best antivirus

I am sorry I am very slow on arabic key board so let me tell you how those things go for the website offered it might not be very correct as they follow different system there is a major independent testing labs called av-comparative and according to their tests the antivirus antivir avira is the best so far besides GDATA AVK those two are ranked first then kaspersky the f-secure then nod32, now for this is for the detction of viruses, but for speed the fastest is avast antivirus and then nod32 and then antivir avira , then you have the ability to detect unknown viruses which are very new, the best two are nod32 and antivir avira and the bitdefender and then kaspersky and so on, if it was up to me I tried over the las three years all of them and I would advice all of you to try nod32, bitdefender, antivir avira because those have the best detction to computer resources ratio if you think you can get any of those it is perfect nothing else can do you better job than those even kaspesky because kaspersky is very heavy, the secret of nod32 being very light though very good for example is that its antivirus engine is written in assembly which is extremly fast meanwhile kaspersky and norton for example are written in c or c plus plus, it is a long story but anyhow this is my recommendation and this is out of hundreds of experiences.
