Browser Hijacker programs

The majority of programs that can be categorized as Browser Hijackers are primarily for the purposes of the online marketing. The developers of those programs are known to earn large amounts of money simply by making sure that their products are getting installed onto enough PC’s. Some Hijackers even appear to have different “useful” functions such as PC optimization, a safer or more comfortable browsing experience, enhanced online security, etc. However, oftentimes what actually happens is that those programs make matters worse for all of the aspects we mentioned above. Besides, most Browser Hijackers do not even try to seem remotely desirable as programs, they just get onto the PC via some stealth installation method and start carrying out their agenda until they are removed.

Malware and Hijackers

So far, a lot of experts have agreed that programs such as Mobifoth cannot be regarded as a form of malware. However, what many people fail to realize is that there is a big difference between an actual malicious PC virus such as for example Ransomware or a Trojan and an annoying and unpleasant program from the Browser Hijacker type. Obviously, Hijackers can undoubtedly be a major pain in the neck, but they are, for the most part, relatively harmless. After all, their purpose is not to lock your files and ask for a ransom payment which is typical for Ransomware or mess with your OS and make your PC unusable which is something Trojans are known for. A Browser Hijacker would use all sorts of aggressive online marketing techniques in order to generate more income for its creator but it would usually not try to harm your PC or data.

Security issues

The purpose of Mobifoth might not be damaging your computer but it could still make it more vulnerable to other programs that could do that. There are a lot of different things that a Hijacker might do which could compromise your machine’s security. For instance, Hijacker are known to mess with the PC’s Registry which can lead to security vulnerabilities making the computer more susceptible to all sorts of hacker attacks. Additionally, software of this type might also display fake and deceitful online offers/browser warnings which might sometimes redirect the user to malicious and dangerous websites. Generally speaking, if a program on your computer tends to display any sort of shady behavior, it should probably be gotten rid of which is why we strongly advise you to utilize our guide and eliminate the unpleasant piece of software.

Stopping Browser Hijackers in the future

In order to prevent any future installations of unwanted programs such as Mobifoth and other Hijackers, it is important that you adhere to a couple of simple, yet momentous protection guidelines and rules:

  • Avoid visiting websites that might expose your system to security hazards. Usually, it is not that difficult to discern which sites could be potentially harmful, yet keep in mind that sometimes there are web addresses that mimic legitimate sites and seem to be trusted while they are in fact shady and possibly even dangerous.
  • Be very careful with file attachments/web-links that get sent to you via e-mails or Facebook/Skype messages. If you have the slightest suspicion that the message might be spam, do not open its contents.
  • Anti-malware programs are usually great at preventing sketchy software like Mobifoth from getting installed on your computer so if you don’t have such a program, consider equipping your machine with one.
  • Our final advice for you is to look out for file bundles when installing new software on your PC. Hijackers are oftentimes added to the installers of other programs and if you fail to notice that and install the program, the Hijacker would get inside your PC as well. Therefore, always examine all options that are available within the setup wizard and if there are added installs which might turn out to be unwanted, be sure to leave them out of the installation before you proceed.
