Trojan:JS/Medfos.B is a JavaScript Trojan that takes over the affected web browser and reroutes search results in Google, Bing, Yahoo, and AOL to doubtful websites. Trojan:JS/Medfos.B is installed as a browser extension for Google Chrome on the corrupted PC; however, if you delete the extension, Trojan:JS/Medfos.B won't be eliminated from the targeted computer. Trojan:JS/Medfos.B is able to regain control of the web browser while it still exists on the machine. Trojan:JS/Medfos.B is downloaded on the victimized PC by another Trojan as a file called 'chromeupdate.crx', which will pose as a genuine extension for Google Chrome. While being installed, Trojan:JS/Medfos.B obtains control over the targeted web browser and reroutes search results in search engines to a website that encompasses and distributes other malware threats. Sometimes, Trojan:JS/Medfos.B shows an advertisement page, which strives to earn money for scammers.
