The S.igmhb.com “malware” falls in the category of potentially unwanted programs (PUP). You may often find that PUPs are sometimes called “browser hijacker”. As their name suggests, such programs are certainly not wanted by the users, because they often display ads, pop-ups and banners that people find annoying and distracting. However, PUPs are legal programs and anti-virus software does not flag them as threats for removal.

Why is S.igmhb.com not a Malware?

As in every advertising business, there is a lot of money in browser hijacker. Developers collect income from every click their ads receive when they are displayed. It has turned into a great cost effective tool for optimizing their advertising and distribution budgets. However, many users, which face S.igmhb.com for the first time, may categorize this browser hijacker activity as an annoying virus. When it comes to speaking about viruses, it is important to differentiate them from browser hijacker. The virus is a type of malicious software that infects your computer and makes changes to your system without your permission.

Potentially unwanted programs, known as browser hijacker, often come packed with other software, which is free to install. PUPs may get in your system when you click the installation process without checking the EULA. If you download and install free software, your computer will also the install the browser hijacker packed within it. When you click OK on the installation process without reviewing it carefully, you give the developers a permission to run this program on your PC. The S.igmhb.com activity is often referred to as annoying, therefore, it has a reputation of an application, which users don’t really want in their system and would rather remove.

How to stay away from browser hijacker such as S.igmhb.com?

Not getting the browser hijacker in the first place is the easiest way to deal with it. For that, be careful when clicking on unknown locations and avoid installing free programs without checking the custom installation option. “But, free software is a great deal, isn’t it?” – you may say. The raw truth is that nothing free comes for free. When you download and install a program, especially programs that claim to be free, carefully monitor every step of the installation process that comes up. The best is to select the custom installation and look for checkmarks that you can uncheck. Look for small text or check boxes that claim to install other programs on your system. Study carefully all the options. This may save you a lot of headache from dealing with potentially unwanted program on your system.

browser hijacker developers target all browsers with a wide variety of plugins and browser hijacker extensions. S.igmhb.com is not an exception. Whichever the browser is – Google Chrome, Mozilla, Internet Explorer – they are all vulnerable to the S.igmhb.com installations.
