Remove Internet Security Guard (Uninstall Guide)

Internet Security Guard is a rogue anti-virus program which works as a disguise. This malware almost makes you think it's legit because it looks like Microsoft Security Essentials, the genuine Microsoft security product. Besides, it has a very generic sounding name. But have you ever heard of it? Hell no. There's another variant of this malware that calls itself Home Security Solutions. For a more technical description read this post. This time I will just stick to the facts, so that if anyone else gets it they know what to do.

Internet Security Guard is distributed through spam e-mails, infected websites, and social networks. It seems that cyber criminals use the BlackHole exploit kit to spread the malware. Upon execution, Internet Security Guard modifies Windows registry and drops several files onto the infected computer. It then pretends to scan your computer for spyware, trojans, rootkits and other malicious software. It may falsely detect up to twenty viruses on your computer. What is more, this rogue antivirus program, blocks legitimate security software and system utilities. Last, but not least, it changes LAN settings by adding a proxy server which redirects http requests through servers controled by cyber criminals. As a results, anti-virus and tech support websites may be blocked. Windows Hosts file might be replaced as well.

Websites in some way associated with Internet Security Guard:
  • hxxp://
  • hxxp://
  • hxxp://

If your computer just got infected with Internet Security Guard, please ignore everything it says and do not follow instructions on screen. But most importantly, DO NOT purhcase it. If you though it was real and you gave your credit card details to scammers, contact your credit card company immediately and dispute the charges.
