Internet Security Essentials
Internet Security Essentials, also InternetSecurityEssentials, is a rogue security software pretending to protect the computer against malware and viruses. It is not to be confused with Webroot's "Webroot Internet Security Essentials" or "Microsoft Security Essentials".
Operation
As a fake antivirus program affecting Microsoft operating systems (Windows 9x, 2000, XP, Vista, Windows 7 and Windows 8) it installs itself through the use of a trojan horse from certain websites of the internet. Once downloaded and operating, it claims to find various viruses and malware on the computer that pose imminent danger scaring the user through pop-ups to buy its protection (scareware), while in reality the program itself is the malware. The virus was first encountered in February 2011. The program disrupts normal operations and should be removed immediately.
