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

Rompilsy looks like a reliable search engine that has many different features. The moment this program gets installed on your PC, you may find some new toolbar or search engine, shortcut buttons to popular sites, games, news and other similar sections in the default browser. Still, do not rush to get excited about the bright design of your replaced homepage and stunning image ads and pop-ups, displayed on your screen, because this program belongs to the category of “browser hijackers”. If you have never heard this term, you should know that programs that fall into this category are not as dangerous as computer viruses, yet they may still be considered unreliable.

In short, browser hijackers are tools that affect browsers like Chrome, Firefox and Internet Explorer in order to show manipulated search results. Such programs often redirect users to questionable webpages, ads, banners, and pop-ups of various types. One of the main reasons for this behavior is to increase the popularity of linked web pages. In return for this service, the creators of software like Rompilsy “Virus” receive money. However, security experts warn that it is very possible, after some of the redirections of the hijacker, to find yourself on a malicious website. For these and some other reasons, it is usually advisable to remove the browser hijackers from your system and uninstall all of their components. You can do this with a professional tool, (like the one available below) or by using our manual removal guide, found at the end of the article.

Rompilsy: basic facts and removal instructions

As already mentioned, it is typical for browser hijackers like Rompilsy to redirect the users to certain domains and expose them to various commercials. In other words, they may show you sponsored search results among the standard ones and make you click on certain ads, links, and pop-ups. These actions are designed to generate visitor traffic to some sponsored web pages and even though they may be quite intrusive, they are not considered illegal or malicious.

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!

However, when you get exposed to hundreds of pop-ups, banners and new pages from unknown advertisers and developers, you should always keep in mind the potential risk of being misled. A program like Rompilsy may eventually fill your screen with some intrusive advertisements and fake warnings, reporting the necessity of a software update or the installation of some plugin. It is good to know that such “suggestions” should be refused, as most of them are normally used by the hackers to promote malware such as Trojans, Ransomware, and other viruses.

Another very common issue with browser hijackers, which often get overlooked by the users, is their ability to collect browsing-related information. Such activity usually helps the developers to learn more about people’s browsing habits and preferences and display some relevant ads. However, programs like Rompilsy may fail to provide the users with information about how the collected data is used and stored and how the privacy policy is implemented. Therefore, we must alert you that the information gathered from your browser may be shared with unknown companies and other advertisers, which may use it as they please. Internet privacy is a problem that is escalating quite a bit, especially because users have ignored it for years. To protect yourself from having your bookmarks, location, social media shares, likes and web searches tracked, we suggest you remove Rompilsy “Virus” and uninstall its components permanently.

How can the hijacker slip into your system?

Have you heard of “bundling” before? This is a widely used software distribution technique, which the developers of browser hijackers and similar potentially unwanted programs commonly employ. They basically “bundle” a piece like Rompilsy inside the installer of another program (usually a freely distributed one) and let the users install it on their system. Since people rarely look twice before clicking on the “Install” button, they often miss the additionally bundled components and this way, they install them together with the main application. To avoid that, you basically have to always select the User/ Advanced settings, no matter whether you are downloading a well-known or completely new tool. These settings will reveal the extra components and will allow you to exclude them from the installation before they get into your device. This will help you avoid hijackers like Rompilsy or even some other nasty threats such as Trojans, Ransomware, and other viruses.
