This page aims to help you remove Google Crash Handler. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

One of the most annoying things that can happen to your PC and to your browsing program is an adware app to get installed on the machine and to get added to the browser. Adware is a specific category of software that consists of programs and apps that normally can’t operate on their own and instead need to get added to a browser in order to function. Normally, popular browsing programs such as Chrome, IE, Firefox and Edge are the main targets of adware since those are used by the most users. Above all, the adware apps seek exposure and need to get onto as many PCs as possible. The reason for that is the main purpose of most such software components which is to advertise stuff on the screens of the users. Random pop-ups, page-redirects, banners, download requests for different programs and other applications, blinking box messages and many more are likely to start spamming your screen the moment you open a browser that has an adware app attached to it. Of course, most users wouldn’t really want to install such software on their machines but this is where the different sneaky installation and distribution methods used by adware apps come into play. File-bundles, e-mail spam messages, misleading and deceitful download prompts from different obscure sites and many similar methods can be used to distribute a given adware program.

Recently, there have been a lot of reports about Google Crash Handler – this is one good example of what you don’t want to have on your computer. Though it isn’t really dangerous like a Ransomware virus or like a Trojan Horse, this adware app is certainly something that you don’t want on your PC and below we will show you how to remove it:

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).


Properties —–> Shortcut. In Target, remove everything after .exe.

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.

  • 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

Security hazards related to adware apps like Google Crash Handler

There is certainly no need to panic if Google Crash Handler has somehow gotten installed on your machine. As we already told you, this isn’t a real virus and it will likely not try to harm the system of your PC or make any damaging changes to it. That said, it’s pretty much never a good thing having an ad-generating piece of software on your PC. On the one hand, it wouldn’t really offer you anything useful in the majority of the cases. On the other hand, the annoying ads are likely going to be way too frustrating for you to tolerate. Not only that, but also you might potentially get your PC exposed to different threats if you aren’t careful. The reason for that is the fact you could never really be certain that any of the ads generated by Google Crash Handler won’t actually link you to dangerous web locations with nasty malware infections like Trojans, Spyware and Ransomware inside of them. Even if Google Crash Handler isn’t really a harmful program, you are still not advised to keep it on your PC or to interact with its ads if you don’t want to risk the security of your PC or files.


Name Google Crash Handler
Type  Adware/Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms  Adware tends to generate pesky ads which is its most typical symptom.
Distribution Method Some of the different ways used to spread such software components are bundling the adware with other programs, putting inside spam messages or linking it to misleading web offers and download prompts.
