The real characteristics of the programs, referred to as browser hijackers:

The differences among the different versions of malware and those of advertising software:

Nothing truly hazardous and harassing like encryption or damage of files is possible in the case of browser hijacker-inflicted infections. These programs differ considerably from the typical Trojan and Ransomware-like viruses. For example, hijackers are practically incapable of accessing anything on your system, either particular files, or entire folders, with the small exception of the records, containing info about your recent online search requests and browsing patterns. The Trojan and Ransomware versions, on the contrary, are very likely to get access to all the components of your system and damage them to a great extent. What makes browser hijackers and the famous virus categories even more diverse are the normal ways these two software types get distributed.

  • Spam – loading an online advertisement, which pops up inside your browser app, could lead to a hijacker infection.
  • Infected websites – some web pages may contain ad-generating software and you could catch it via willingly or unwillingly downloading anything from such a website.

Such mixes may contain ad-producing programs like Critical Firefox Update “Virus” Popup. More precisely, you CAN’T get infected with any browser hijacker simply by downloading a bundle for free. Actually, the only way to catch such a program is to install the entire content of such a bundle.
