Summary

TrojanDownloader:Win32/Zlob is generic detection for a component of the greater Win32/Zlob malware family. Win32/Zlob refers to a large multi-component family of malware that modifies Internet Explorer's settings, alters and redirects the user's default Internet search page and home page, and attempts to download and execute arbitrary files (including additional malicious software). The Win32/Zlob family has also been associated with rogue security programs that display misleading warnings regarding bogus malware infections.
Manual removal is not recommended. To detect and remove this Trojan and other malicious software that may have been installed, run a full-system scan with an up-to-date antivirus product such as the Microsoft Safety Scanner (http://go.microsoft.com/fwlink/?LinkId=212742).
