This page aims to help you remove JZip “Malware”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

In the current write-up, we are going to go over a software product known as JZip – this is a file compression tool, based on the famous and reputed 7Zip data compression program, that is available for free on the Internet and could be downloaded by anyone. However, reports by cyber security experts suggest that this program might possess certain questionable qualities and features which is why it falls under the category of the potentially unwanted programs (PUPs). Below,w e will explain to you what the reasons for deeming JZip a PUP are and why you might not want this piece of software on your PC. Also, we will offer you a guide for removing the app in case you decide you should get rid of it. The reason why a specialized removal guide might be needed in order to get rid of the potentially unwanted program is because it is possible that it might not be so easy to have it uninstalled in the same way you might be used to uninstalling other programs. Also, certain leftover components might remain in your system even after uninstalling the program in question. This is why, we advise you to resort to the instructions from the guide on this page or use the professional removal program which you can also find in the guide down below.

Why you might want to remove JZip

There isn’t anything to suggest that JZip has any harmful abilities – we aren’t saying that this is a piece of software similar to a malware virus such as a Worm, a Trojan Horse or a Ransomware infection. However, JZip might indeed possess certain abilities and features that can be regarded as suspicious and questionable. From some of the alternative ways of distribution that are used for this software to the “extra” activities it might execute while its active on your PC, there are quite a few things to be mentioned that might be seen as reasons for removing this piece of software from any computer. As we said, the next guide will help you with the task of uninstalling this PUP but if you want to learn more about it and what its potentially undesirable qualities might be, be sure to read the remainder of this article.

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 

Step3

Hold together the Start Key and R. Type appwiz.cpl –> OK.

appwiz

You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:

msconfig_opt

Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

Step4

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
  2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Why it is seen as a PUP

One of the main things to mention here are the official site of this program and its developer. The main page of the site of JZip contains a short description of the program and a download key. There are several links on this page that lead to the EULA and the Privacy Policy but some of those links redirect to blank pages such as the Uninstall Instructions and the Contact Us links. Also, the developer of the program, “Prssto Inc.”, is an unknown company with no information about it on the Internet. By themselves, those two rather questionable facts about JZip should be enough to raise suspicion but there are more things to be mentioned.

The main issue with this program is that it seems to randomly force the user’s browser to load new-tabs/pages that are seemingly empty. However, researchers have revealed that those pages aren’t really empty but instead contain hidden ads. This leads to the logical conclusion that JZip seems to be carrying out a hidden advertising agenda without the users even knowing about it. This is yet another rather questionable trait of the program and another reason for it to be considered a PUP.

Distribution techniques

The reports on JZip also state that, aside from its obvious distribution method – the download link/button in its official site, this program can also get installed on the users’ computers by being bundled with or otherwise distributed via other potentially unwanted programs and apps such as Adware, Browser Hijackers, Bloatware and so on. Typically, any software that needs to get distributed by such programs and apps is seen as suspicious and maybe potentially unwanted which is yet another reason for JZip to be put under the PUP category.

Conclusion

JZip is, of course, not a virus – it is not some dangerous Ransomware or Trojan Horse program and will likely not harm your computer. In fact, many users might find it helpful or at least functional. However, there are still the rather suspicious aspects of this program that we mentioned and we believe that there’s really no need to take any unnecessary chances with questionable software pieces like this one, especially since there are many programs out there that have better reputation and that have developers who are much more transparent in their policies.

SUMMARY:

Name JZip
Type PUP
Danger Level Low (unlikely to cause harm to your PC but could still be rather irritating and might increase the chances of getting your machine exposed to actual malware)
Symptoms Random seemingly empty new tabs and new pages opening in your browser while you are surfing the Internet.
Distribution Method Through the official site of the program and also through software bundles.
Detection Tool We generally recommend SpyHunter or a similar anti-malware program that is updated daily.
