If you are subjected to a large number of pop-ups and banners that appear on every page you visit and you are reading this article then you’ve correctly assumed that “DLLRegisterServer Failed” is the cause of this behavior. This Browser Hijacker application is actually not malicious – at least not directly. Do not be fooled  though– the only reason for its existence is to spam your screen with Ads. Its creator is paid a small amount of money every time a person on an infected computer follows these Ads.

Why was your PC targeted by “DLLRegisterServer Failed”?

Luckily Browser Hijacker applications like this are not known for their selective picking of targets. Rather Browser Hijacker-infected executables are released in masse and at large in order to target as large number of computers as possible. You simply had the bad luck of obtaining and running such an executable on your PC. To avoid the same fate in the future please try to only obtain .exe files from the official sources for them. Torrents, could storage sites, forums, blogs and other P2P network are favorited by the hackers to spread many nasty viruses. Another popular (and sadly legal) trick used is the so called software bundle. This is actually an executable installer for some other 3rd party program – usually free one. What you don’t know, however, is that this installer has a bunch of other programs inside of it. If you try to run the installer using the Default/Quick installation option it will also automatically install the extra programs – usually the likes of “DLLRegisterServer Failed”. To avoid this simply select the Advanced installation option and go through the sub-menus. At a certain point you will be gives a list of all programs that are about to be installed – simply remove the unwanted extras from this list.

Get rid of “DLLRegisterServer Failed” as soon as possible

Although Browser Hijacker is not regarded as malicious it remains both useless and annoying. Ads created by it will mostly advertise little known bloatware applications. These types of programs are usually focused in the PC security&optimization sphere, but the only thing they actually do is create fake or grossly exaggerated problem reports and scans. Old and perfectly harmless registry entries are commonly labeled as dangerous or blamed for any slowness you may be experiencing with your PC. The sad fact is that most of the time that slowness is actually caused by the Browser Hijacker itself, because your CPU has to share system resources with it.

“DLLRegisterServer Failed” is added an as add-on extension to all popular browsers – Firefox, Chrome and IE are all equally vulnerable. Uninstalling it can also be a bit tricky, because simply removing it from the list of extensions is sometimes not enough. You will find the detailed guide on how to remove “DLLRegisterServer Failed” below.

DLLRegisterServer Failed Fix


 

Step1

Reboot in Safe Mode (use this guide if you don’t know how to do it).

This is just the first preparation.

Step2

WARNING!
To remove parasite, you may have to meddle with system files and registries. Making a mistake and deleting the wrong thing may damage your system.
Avoid this by using SpyHunter - a professional Parasite removal tool.

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

The first mandatory thing is to Reveal All Hidden Files and Folders. Read here more how to do it. Each version of Windows does this slightly differently.

  • I repeat – it’s extremely important you do this. “DLLRegisterServer Failed” may have hidden some of its files and you need to see them to delete them.

Also, repeat Step 2 for ALL browsers you have installed – the virus probably infected them all.

Click chrome menu icon again, and proceed to Settings —> Search, the fourth tab, select Manage Search Engines. Delete everything but the search engines you normally use. After that Reset Your Chrome Settings.

 

Step3

Right click on the browser’s shortcut, then click Properties.

NOTE: We are showing Google Chrome, but the method is the same for Chrome, Firefox, Internet Explorer, Safari, and Microsoft Edge.

Once you’ve reached Properties —–> Shortcut (on the band at the top), then in the Target type field, delete EVERYTHING AFTER .exe.

Step4

Hold the Start Key and R together. Write appwiz.cpl in the field, then click OK.

appwiz

You are now in the Control Panel. Uninstall any suspicious programs. Also, viruses often spend one last ditch effort to trick you into installing more of their kind. If you see a screen like this when you click Uninstall, choose NO:

virus-removal1

Hold the Start Key and R againthen copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A .txt file will open – don’t type or change it. If you are hacked and someone has access to your PC, there will be a bunch of other IPs connected to you at the bottom. This is what a hosts file looks like:

hosts_opt (1)

If there are a bunch of strange IPs connecting to you below “Localhost” you may be hacked, and it’s best to ask us in the comments for directions.

Step5

Right click on the Taskbar and choose “Start Task Manager.”

virus-taskbar123

Then click the Processes Tab. Look at all of the processes in front of you and try to determine which ones are a virus. Google them or ask us in the comments and we will provide the best assistance we can.

A BIG WARNING HERE! READ THIS BEFORE PROCEEDING!

This is perhaps the most important and difficult step, so be extremely careful. Doing this can damage your system significantly if you make a big mistake. If you are not feeling comfortable, we advise you to download a professional remover. Additionally, accounts connected to your credit cards, or important information, may be exposed to the virus.

If you do not remove the virus completely it could leak the information to its creator, so be careful!

malware-start-taskbar

Right click on each of the virus processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a virus, copy the folders somewhere, then delete the directories you were sent to.

Step6

Take a look at the following things:

Type msconfig in the search field and hit enter: you will be transported to a Pop Up window.

msconfig_opt

Go in the Startup tab and Uncheck entries that have “Unknown” as Manufacturer.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If you can’t find them this way, look in these directories, and delete/uninstall the registries manually:

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