Malware Related [Trojan/Spyware]
Some malware may arrive from an email or execute from a malicious Web site. Once installed, it modifies the Windows Hosts file in such a way that whenever the user visits certain legitimate business sites, such as banks or credit card companies, the browser will be redirected to a spoofed Web site.
Some are memory-resident, meaning they monitor the affected user's Internet browsing activities and wait for the user to visit certain legitimate business sites, such as banks or credit card companies, where they activate.
When the title bar of any window contains certain strings related to the targeted business is activated, a bogus logon window is displayed that is used to trick the user into entering personal account information. Once gathered, the personal information is sent to the malicious user via email.
