Avira, the company known for its Free Antivirus, has just released the first testing version of Avira Protection Cloud, a new cloud-based antivirus.
This is the most simple software I have ever seen. There are no menus here, no toolbars, no options, settings anything else: all you have to do is launch the program, click "Cloud Scan" and wait for the results. It scans running processes, startup programs, Windows services and other likely targets of infection, calculating a hash (a digital fingerprint) for each one and sending it to Avira's server. If this matches any known malware you'll be warned right away.
Occasionally the program will find an executable file it doesn’t recognize, though, and this will be uploaded for analysis. Which could take a while if there are a few, or you’ve a slow internet connection (and there's currently no way that uploading can be disabled).
