Conficker remains the most often detected computer threat

Analysis of ESET’s ThreatSense.Net , a sophisticated malware reporting and tracking system, shows that the highest number of detections in April, with almost 8,70% of the total, was scored by the Win32/Conficker class of threat. It is a network worm originally propagated by exploiting a recent vulnerability in the Windows operating system. Depending on the variant, it may also spread viac unsecured shared folders and by removable media, making use of the Autorun facility enabled at present by default in Windows (though Microsoft have announced that it won’t be enabled in Windows 7).

INF/Autorun takes the second place with 8,55% of all detected threats. This detection label is used to describe a variety of malware using the file autorun.inf as a way of compromising a PC.

The No.3 in April chart of topmost malware is the family of Trojans with keylogging and (sometimes) rootkit capabilities which gather information relating to online games and credential for participating labeled by ESET as Win32/PSW.OnLineGames (7,01%).

Next down on the list is Win32/Agent (3,51%). ESET describes this detection of malicious code as generic, as it describes members of a broad malware family capable of stealing user information from infected PCs. The Win32/TrojanDownloader ranked as No.5 in April with 1,03% designates a broad class of malware commonly used to download and install other malicious components on an infected computer, and includes the currently prevalent Win32/TrojanDownloader.Wigon and Win32/TrojanDownloader.Swizzor.
