Ihdefender.exe stands for the main process of Internet Security Pro, another sample of a fake security software which targets many PCs worldwide, without prejudice to country, location, gender of race of computer owners. This online threat gets into infected computers when you don’t expect it to come. Unlike many other bogus anti-viruses, it attacks your PC in a secret (hidden) manner, being installed without your consent or participation. Be careful when surfing accounts like Facebook, Twitter, etc. There can be a risk of some links being infected and, upon clicking, leading you to the hidden installers of this malicious tool.
