Avira Anti Virus
Avira Anti Virus is a highly recommended Antivirus Software. It is extremely user friendly, easy to install and setup and does a great job in removing a wide range of Internet threats such as viruses, spyware (malware), phishing, etc... Just like AVG Antivirus it has a low impact on processing power and consumes little memory. This is extremely important when it comes down to deciding which Antivirus Software to use. I like it how Avira Anti Virus doesn't hog the memory of the computer or slow down computer processes while it is running.
There are four levels of software that Avira Internet Security package offers:
Basic protection: which protects the computer against viruses, worms and Trojans (malware)
