NAME: Swizzor
ALIAS: TrojanDownloader.Win32.Swizzor, TrojanDownloader.Win32.Swizzor.b
The TrojanDownloader.Win32.Swizzor.b is a small program that can come to a user's system when he or she is browsing the WEB. The program downloads and installs a LOP.COM-related plugin that acts as a spyware/adware and provides customized search capabilities.
As downloading and installation happens without a notification to a user and user's approval, we added detection for the downloader as a trojan.
To remove the downloader it's enough to delete its file from a hard drive.
