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