Do you know what WiniFighter is?
WiniFighter is a fake anti-spyware and security application. WiniFighter pretends to be an application that is able to detect and remove security related issues and parasites from your computer. WiniFighter will not perform either of those functions. Instead, WiniFighter uses various tactics to force you into purchasing a full version of WiniFighter.
WiniFighter, after installed, may display fake Windows Security Center messages and possibly redirect you to malicious sites that could prompt the download of other malware. WiniFighter may initially come from a Trojan that automatically installs it without permission.
In non-techie terms:
WiniFighter is not much different from other rogue anti-spyware programs. Do not purchase or voluntarily install WiniFighter under any circumstances. Removal of WiniFighter may be difficult to perform manually because it is known to load at startup of Windows into the system memory.
