Avira Antivirus Suite 

From malware and Trojans to spies and identity theft, Avira’s

NEW Antivirus Suite gives you the protection you need to live the life you want. Protect your files with 5 GB of safe

and secure online backup. Detection technology leaves

nowhere for malware to hide. It runs completely silent without bothering you with all kinds of messages or something similar. On top of that, it is extremely light on your system resources. Avira found and disarmed all of the rootkits and other malware infections tossed at it. Avira's program was not just the most thorough tool of the group, but also the fastest. It led in speed tests for both on-demand scans (which you schedule or start manually) and on-access scans (which happen automatically during tasks such as copying files).
