Whether you are using Avira, AVG, Kaspersky, Norton, ESET, Avast, Comodo and etc, all of them slows Windows down and that is a fact. Most Windows users needs an antivirus because it can protect their computer from most viruses that are spreading through network, internet and USB flash drives. Without an antivirus, the user can get infected by virus, spyware, trojan, worms, bots very easily and quickly if they have not much knowledge in computers. Even though I know the importance of an antivirus software, I don’t really like to install them on my computers because of one simple reason only and that is slowing down in everything I do on the computer.

I do fine most of the time without an antivirus because like I said before I always test run and analyze any suspicious file that I downloaded on the Internet on another computer that is running a clean Windows without anything that the virus can steal or damage. However as a tech guy, I am faced with the ultimate question of which is the fastest / lightest / best antivirus? It is really hard to say which one is the best because there are a lot of points that has to be taken into consideration such as the performance, detection and removal.

I have completed 2 performance tests so far and I have to admit that both tests are flawed and inaccurate. The test is fair because the antiviruses are tested on the same computer with the same steps and method. However there are some illogical part of it which I will explain more in detail.
