This page aims to help you remove Putrr18 “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

If you have recently seen some new homepage or search engine that says “Powered by Putrr18 “Virus”” in your Firefox, Chrome or IE browser, then this could be a sign that in your system, there is a browser hijacker called Putrr18 “Virus”. A browser hijacker is a potentially unwanted piece of software, which may cause you certain browsing disturbance and irritation due to the frequent search redirects, ads, pop-ups, new tabs and banners that it can initiate. In this article, you can learn all the basics about this type of software, as well as the specifics of Putrr18 “Virus”, its distribution methods, and successful uninstallation. The removal guide below is all at your disposal in a case you decide to remove this particular program and save yourself from its activities.

Where can Putrr18 “Virus” be found and how can it invade my PC?

According to recent reports, this as well as other browser hijacking pieces of software are mostly distributed through different web pages, where free downloads are available, such as torrent sites, freeware or shareware platforms, spam messages, ads and automatic installers. If you often visit such web pages and frequently download software from them, then you should know that some installers may contain additionally bundled components (adware, browser hijackers, ad-generating apps), which may automatically get installed on your PC along with the free program that you install. For this reason, you need to be more careful during the free software installation process. You are going to learn more about prevention in the next paragraphs.

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:

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

  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.

What is the difference between a browser hijacker and a virus?

If your browsing is getting interrupted by a browser hijacker for the first time, you may not know whether this is a virus (some Trojan horse or some tricky Ransomware) or just some annoying software. Many users are not really sure about the danger level of programs like Putrr18 “Virus”, that’s why they often seek our help. Fortunately, we need to say that no browser hijacker has ever been reported as malicious so far, therefore, we have no reason to accuse Putrr18 “Virus” in any harmful intentions. In fact, such software is used basically for aggressive online advertising and exposure to specific sponsored sites and promotions. The creators of browser hijackers are trying to make some money through a method known as pay-per-click, which has nothing to do with criminal schemes, such as Ransomware or other harmful techniques. This method normally prompts the users to click on ads and links that appear in their search results with the help of the hijacker and then redirects them to certain web pages. In return for causing traffic to these particular pages, their owners pay a certain amount to the owners of the browser hijacker. Apart from the redirecting service, a piece like Putrr18 “Virus” may track your web searches to be able to show you more attractive ads during your search. In most cases, it collects information about the search queries, most visited web pages, email addresses, and other similar data. No matter how harmless you find disclosing such information, it’s a good idea to avoid the programs that collect it. Otherwise, you may start receiving more spam emails in your email or lots of misleading ads in your search results. To protect yourself from this, consider uninstalling this hijacker. To do this, you just need to scan your system with reliable malware removal software like the one below or, alternatively, use the instructions in the guide to detect and manually remove the unwanted software. 

How to protect your PC from Putrr18 “Virus” and similar browser hijackers?

To protect your computer from Putrr18 “Virus”, you should be very careful when downloading free software to your computer. As we already mentioned above, no matter how reliable a program you are about to install seems to be, read the Licensed End User Agreement, the Privacy Statement, and other available information first. If you find nothing suspicious, then make sure that you select the Advanced or Custom Setup settings when you run the installer. Be sure to check all the bookmarks that are marked and pay extra attention if you notice some additional check boxes that provide “extra components”. If you see a message that you are agreeing to install a browser plug-in, a toolbar, or some extension, be sure to uncheck it. Otherwise, you may install the browser hijacker on your computer.
