Three New Threats With Highest Percentages in Top Ten

The latest statistics by ESET's ThreatSence.Net gathered from a detection test on millions of PCs around the world showed that the top three threats to computer users were all new in the 'top ten' list in February, reports Viruradar on March 8, 2007.

The report indicates that the level of detection for W32/Adware.Yisou malware was exceptionally high during February. The adware was at the third spot in the month's top ten list, reported software firm ESET.

The Win32/Nuwar.gen was in the first place with 3.65%. The worm belongs to the family that spread widely since the start of 2007. A web-based threat, HTML/ TrojanClicker.Agent.A, ranked second in the February top ten list reaching 3.63% of detections. A Trojan, this threat takes advantage of vulnerabilities in web browsers that attempts to download other items of malware. The adware Win32/Adware.Tisou took up the third place with 3.14%.

Paul Brook, managing director of ESET, UK, commented that such high detection levels are unusual to find.

Brook further said that Win32/Adware.Yisou is a keyword in the search function of IE's address bar that enables users to search with Chinese characters, which could be helpful for servers. But it posts pop-ups that are most difficult to uninstall. Therefore, it proves very unpopular among users who are not literate in Chinese and have inadvertently installed it. News by bcs.org published Brook's comments on March 7, 2007.

The detection statistics were collected from NOD32 users, reports ThreatSence.Net. While these users facilitate the product's reporting service, the statistics give the view on the behavior and spread of malware in a comprehensive manner. The current data was gathered from 10 million or more computer systems. It has ascertained behavior and origin of a variety of about 10,000 threats and malware groups.

The top ten threats along with their percentages in February 2007 were reported as Win32/Nuwar.gen-3.65%, HTML/TrojanClicker.Agent.A-3.63%, WIN32/Adware.Yisou - 3.14%, Win32/Netsky.Q-1.76%, Win32/PSW.QQRob-1.36%, Win32/Adware.Boran-1.32%, Win32/Adware.180Solutions-1.27%, Win32/Rjump.A-1.18%, Win32/TrojanDownloader.Delf.BEN-1.17%, Win32/TrojanProxy.Dlena - 1.09%.

Security firm Symantec recently reported that 2% of adware could install and execute itself on Windows Vista operating system even though the OS had advanced security features.
