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

What is Winsecurity “Virus” and why should you avoid its sketchy popping ads and redirects?

Winsecurity “Virus” is a legitimate program of the browser-hijacking type, which can easily integrate with Google Chrome, Mozilla Firefox, Internet Explorer, Safari and other popular search engines. Typically, this program is distributed in a bundle with some other free or attractive apps and can get into the system if you run the installation pack without customizing it. After it becomes part of your system, Winsecurity “Virus” may modify your browser settings and cause other potentially unwanted changes such as:

  • Set a certain sponsored website as the default search engine and/or homepage;
  • Block user access to other search engines from the browser homepage;
  • Redirect to suspicious web pages;
  • Provide plenty of online ads, pop-ups, and banners;
  • Track browsing-related information and transmit it to third parties.

If you’re looking for online reviews for Winsecurity “Virus”, you may find that users complain about most of the above-described issues. Some of them even refer to the program as a virus. In addition, they report that removing the browser hijacker is also a problem. In fact, research shows that this potentially unwanted program is designed to impose certain browser changes or install browser assistant elements in such a way, that it is very tricky for the users to uninstall them without special assistance or a proper removal guide. The aim is to keep the hijacking software on the affected device for longer and make money for its developers from online advertising via Pay-Per-Click or Pay-Per-View ads. But what if you want to get rid of it? Check out the next lines for more details.

What may Winsecurity “Virus” do?

After Winsecurity “Virus” hijacks the default browser, the users may find that their home page is set to another one and their search engine is replaced. While this is surprising, the search engine may look reliable and safe to use. There might be a number of quick access features to popular websites and other tools that seem to enhance the browsing experience. Still, if you are not interested in this and want to get rid of this tool, you may have some problems. If you think it’s enough to remove Winsecurity “Virus” from the settings of the affected browser, you’re wrong. Once you delete its URL, it will reappear after you restart your computer. To completely uninstall the hijacker, you need to check the entire system and look for suspicious entries that may have been installed. At the end of the page, we have published a detailed removal guide on that, and we strongly advise you to follow it to detect and uninstall all the related hijacker scripts.

If you leave Winsecurity “Virus” on your system, it may lead you to a number of browsing problems and can expose your computer to some privacy and security hazards. We do not say that this software is malicious and definitely, it has nothing in common with computer viruses such as Ransomware and Trojans, but as previously mentioned, the hijacker can show commercial content and prompt you to click on certain aggressive and nagging ads, links and pop-ups without your approval. This activity does not aim to cause you harm or infect you with viruses, however, in a way it can be risky.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

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:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

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. 


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.

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


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


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.



  • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

Right click on the browser’s shortcut —> Properties.

NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Type Regedit in the windows search field and press Enter.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

Although the sole idea behind the aggressive ad generation and browse redirects is to make money from online advertising via Pay-Per-Click or Pay-Per-View ads, it’s not a good idea to trust the hijacker and its content. It may eventually show intrusive and misleading online ads that can lead you to potentially dangerous web pages. The problem is that the developers of such software do not pay attention to the content they are promoting and what threats may hide behind the landing pages. That’s why you can easily run on sites that are compromised or designed to distribute malicious software such as Trojans, Ransomare, Spyware or other viruses. Therefore, you need to consider uninstalling Winsecurity “Virus” so you do not become a victim of some nasty infection.

To quickly and easily remove the hijacker, we recommend that you use a professional anti-malware program such as the one below. It will help you find suspicious components in the system and delete them from there in a few minutes. Otherwise, it may take a long time to do this manually. However, if you trust your computing skills and have some basic understanding of browser hijackers, the manual removal guide is at your disposal and can help you do the same all on your own.


Name Winsecurity
Type Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms  Intrusive generation of ads, sudden page redirects, homepage or search engine modifications.
Distribution Method Software bundles, spam, free installers, direct download links and attachments are the most common sources, but you may also come across this program on different freeware or shareware sites, torrent platforms, ads and free download links.
Detection Tool

Keep in mind, SpyHunter’s malware detection tool is free. To remove the infection, you’ll need to purchase the full version. More information about SpyHunter and steps to uninstall.
