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. Win32.Worm.Licat
Win32.Worm.Licat is a worm that monitors an infected PC. It sends information back to the attacker and downloads files onto the victim’s computer, dependant on certain events.

2. Win32.TrojanDownloader.Zlob
Win32.TrojanDownloader.Zlob is the "original" fake codec malware. It disguises itself as a media codec that is needed to be installed for the user to view a certain movie (often pornographic content). Once installed, the user will get a barrage of pop-ups and security warnings consisting mainly of casino advertisements and rogue applications.

3. Win32.Rootkit.Agent
Win32.Rootkit.Agent is a generic family for rootkits. A rootkit is a program that fraudulently gains or maintains administrator level access that may also execute in a manner that prevents detection. They can be used to monitor traffic and keystrokes, create a backdoor into the system for the hacker's use, alter log files, attack other machines on the network, and alter existing system tools to avoid detection.

4. Online Games
Win32.TrojanPWS.Onlinegames is a family of threats consisting of password stealers that are aimed at stealing log-in information from online gamers. Online game accounts are then plundered and/or sold for a profit. Popularly targeted games include World of Warcraft and Legend of Mir.

5. FakeAlert
