Asian users see adware rise
Bournemouth, UK (5th March 2007) –The top three threats to computer users in February were all new to the top ten according to the latest data from ESET’s ThreatSence.Net, which reports detection statistics from millions of client computers around the world.
In first place is Win32/Nuwar.gen 3.65%, part of the family of worms that has achieved wide propagation since the beginning of the year. Second in the ranking for February is a web-based threat, HTML/TrojanClicker.Agent.A, which reached 3.63% of detections during last month. This threat is a trojan that exploits web browser vulnerabilities to download other malware components. Finally adware, Win32/Adware.Yisou, which has been particularly widespread among Asian users, pops up in third place with 3.14%.
“Although Win32/Adware.Yisou is by no means new, it is very unusual to see such high levels of detection reported,” comments Paul Brook, managing director of ESET UK. “Win32/Adware.Yisou is a keyword-lookup tool that takes over the search feature of IE's address bar and allows users to search using Chinese characters, which might be useful. Unfortunately it also delivers pop-ups and is extremely difficult to uninstall making it very unpopular with non-Chinese literate users that accidentally install it.”
