Avira AntiVir Personal

Aviras anti-virus software has for a long time been scoring high at various tests and comparisons against other similar software, and in many tests it is the highest scoring free anti-virus software. What the free edition is lacking, is the ability to remove adware and spyware, and of course there is no support other than access to the online help forums and knowledge databases. But if you feel you can do without, then this edition is perfect for you. The software keeps itself updatet automatically, and can be set up to perform regular scans of your whole computer, or specific drives or folders.
