Threat Check

What types of threats have been plaguing computer users this past month? Take a look, below, at the top threats creating a buzz among Ad-Aware users in the Lavasoft Support Forums.

1. Virtumonde
Virtumonde, also known as Vundo, is a type of malware/adware that often requires special help, or tools, to remove. It hooks itself into the system and then displays pop-ups. It has also been seen, though not as commonly, popping-up fake alerts for rogue anti-spyware.

2. Win32.Trojan.Spy
Win32.Trojan.Spy is a generic family for Trojan spy malware, capable of spying on the victim’s activities (logging keystrokes, recording web pages visited, etc) and reporting the results back to a main server.

3. MyWebSearch
MyWebSearch is a toolbar that is bundled with functionally unrelated FunWeb products. This potentially unwanted application installs without providing sufficient notice and choice to users and does not secure their full, meaningful and informed consent prior to installation. MyWebSearch toolbar is installed on all user accounts and runs an application hidden from view, operating in stealth.

4. Win32.Backdoor.Sdbot
Win32.Backdoor.Sdbot is a backdoor family that contains different versions of the SDbot, which uses Internet Relay Chat (IRC) to communicate. Win32.Backdoor.Sdbot is able to open up a backdoor on a compromised computer, allowing remote access and control of the victim’s machine.

5. AntiVirus2009
AntiVirus2009 is rogue anti-spyware that spreads by way of Zlob and fake online scanners. Its distribution methods are stealthy and/or misleading. The user is presented with misleading advertisements, often popped-up from files and processes installed by Trojans, which ultimately scare or trick the user into buying the commercial version.
