If you are looking for an effective way to remove Ozipcompression Virus, then stop here and read the information below. This page is dedicated to explaining to you how to recognize the browser hijacker that has probably taken over your Chrome or Firefox browser and how to safely uninstall it from your system. We will also give you some more details about the way it may modify your search engine or homepage, install some unfamiliar toolbar on your browser or redirect your searches to different sponsored web pages, ads, and promotions. This way, you will gain a better understanding of the way this type of software operates and will be able to successfully deal with it and remove all of its traces from your system.

Ozipcompression Browser Redirect

Browser hijacker specifics:

One of the most commonly spread types of software on the web is known as Browser hijackers. Luckily, unlike computer viruses and malware like Trojans, Ransomware, Spyware, etc., this software is not really dangerous and cannot do serious harm to your PC. Ozipcompression Virus is one of the typical representatives of the browser hijackers’ family and here we are going to explain its specifics. Generally, programs like Ozipcompression Virus could be classified as marketing-oriented tools, which serve the needs of the online advertising industry but they can also be referred to as potentially unwanted programs. The reason for that is the browsing disturbance they may create. It is usually related to the enormous amount of advertisements they can display and the rather undesired changes they may impose to the users’ default browser. Replacements in your homepage or the search engine, new tabs, ads, pop-ups and unstoppable page redirects – they may all be initiated by a program of this type and this often happens without your approval. The developers, who stand behind the browser hijacker, have a good reason to do that – they usually involve this type of software into a Pay-Per-Click remuneration scheme and earn from the clicks on the ads and the redirects that they display on your screen. This, however, may be quite annoying for you as a user, especially if your normal browsing activity is hampered by the browser hijacker intrusiveness. For many people, this is also one of the main reasons to uninstall this type of software. But can it cause some other disturbance too? Let’s find out.

Does Ozipcompression Virus have something in common with computer viruses?

Fortunately, no. Browser hijackers like Ozipcompression Virus are quite different than most of common malware versions. Viruses, Trojan horses, Ransomware, etc. are usually created by cyber criminals for the purpose of destruction, online fraud and different criminal deeds. Ozipcompression Virus, on the other hand, is a legally developed program. It does not aim to do harm to your system. It can only affect your default browser for the purpose of its Pay-Per-Click advertising activity. No other files or programs will be affected, so you really have no reason to feel compromised by this type of software. However, you may feel disturbed by it, especially if your browsing is constantly interrupted by tens of aggressively popping ads every time you try to open your browser. If this is a good reason for you to uninstall Ozipcompression Virus, then you have all the right to do so. In the guide below we will show you the steps for that, but first, let us tell you how this type of software spreads on the web and how to keep your PC safe in the future.

Browser hijacker distribution and prevention:

Programs like Ozipcompression Virus can be commonly found on many web locations – different free installers, direct downloads, spam messages and emails, too-good-to-be-true offers, ads and sketchy websites, torrents, or different freeware and shareware platforms. However, they cannot get inside your PC the way that a tricky virus or a Trojan-Ransomware infection could. To become part of your system, you need to willingly install the browser hijacker. In most of the cases, however, you may do that without knowing it by running a software setup where such a program is bundled. It is very common that most of the free programs and new apps come along with some ad-generating software packed inside their installer and if you are not careful enough when installing them, you may end up with a program like Ozipcompression Virus on your PC. To prevent that, we would advise you to always use the “Advanced/Custom/Manual” installation option instead of the “Standard/Quick/Automatic” one. This can save you from a lot of trouble dealing with different potentially unwanted software and can prevent it from being installed without you knowing it.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

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. 


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


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

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:

hosts_opt (1)

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.
  3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.
