Avast Tops AV-Comparatives Independent Anti-Virus Testing

PRAGUE, CZECH REPUBLIC--(Marketwire - September 30, 2009) - ALWIL Software, makers of avast!, antivirus software used by over 90 million people worldwide, today announced its software has topped the latest AV-Comparatives testing and analysis in speed and accuracy.

In its recent report titled, "On-Demand Detection of Malicious Software," AV-Comparatives, an independent, non-profit testing organization, found that Avast had the fastest scan time of the 16 tested programs, two to three times faster than most other programs. Speed was just part of the winning formula. Avast was the only program out of those tested to get a top five finish for both malware detection and low numbers of false positives.

"Fast, unobtrusive, and secure is what users want," said Vince Steckler, CEO of ALWIL Software. "It's very difficult to produce an antivirus product that is not only fast but also effective without false alarms. But this is what users want and need -- and what we have provided."

The AV-Comparatives rating balanced malware detection with the number of false alarms, recognizing programs that identified malware with a minimum of false positives. Typically, programs with the highest detection rates also have the highest numbers of false positives -- often creating additional problems for computer users. "These elements can be mutually exclusive and it is very hard to get top scores in each category," said Steckler. "The best antivirus product is not necessarily the one with the best detection -- it is the one with the best blend of these three elements."

Programs recognized by AV-Comparatives as "Advanced+" detected at least 97 percent of the nearly 1.6 billion malware samples with 15 or fewer false positives. Avast was well over this threshold, catching 98 percent of the malware thrown at it. With only five false positives, Avast was at the top of its class for this variable among the 16 tested programs.

"We really upgraded our ability to reduce the number of false positives -- we added over 150,000 files to our known clean set," said Ondrej Vlcek, chief technology officer at ALWIL Software. "Overall, we are showing a fast, progressive improvement in these tests."
