Installation and System Requirements
AntiVir Personal edition runs on Windows 7, Vista and XP. Windows 2000 users can still use AntiVir program but Avira will stop supporting Windows 2000 on July 13, 2011. Please note Microsoft has discontinued support to Windows 2000. Avira wrote on their website that the AntiVir ProActiv technology in the paid solutions of Avira will not run in Windows 2000. This is why using unsupported operating systems is not recommended.
Please note that I recommend getting AntiVir from the vendors' website or reputable download sites only. There are many rogue antivirus distributors that are exploiting the name of legitimate antivirus programs. Avira antivirus download is located here on their website. The program is currently available in 9 languages.
The installation of AntiVir Free is a quick process using its Express install method. A custom installation is also offered but I recommend using the custom install, only if you are advanced user. If Windows Defender is enabled in Vista and Windows 7 or installed in XP, AntiVir recommends disabling Windows Defender manually:
The configuration wizard for AntiVir 10 is presented after installing AntiVir using the "custom" install. To take advantage of better protection, I recommend using the high detection level:
You should also configure Avira AntiVir to detect all types of threats that the program is capable of detecting: Also, you should configure AntiVir Guard to use the Secure mode so it will start as early as possible to immediately block or remove malware that will auto-start right after the user login to Windows:
Other recommended settings are to allow AntiVir scanner and guard to scan all files by choosing the Expert mode in the Configuration window. Use this setting only if you have enough RAM installed on your computer: Finally, configure AntiVir by enabling the advanced processes protection for the program
