BSOD Error 333 Virus Removal

This article aims to help users remove  from Chrome, Firefox, Internet Explorer and Safari, as well as their respective system.

BSOD Error 333 Virus

What you are dealing with in the face of BSOD Error 333 is an Adware virus. These viruses are not believed to be very dangerous, because they are not capable of inflicting damage or stealing data on their own. However, they are still classified as viruses and should not be taken lightly. They often serve as backdoor entrance points to other, more dangerous viruses and thus BSOD Error 333 should be cleaned out from your machine as soon as possible.

A couple of things you should absolutely never do until you remove BSOD Error 333

As mentioned above BSOD Error 333 may be used as a “dropper” for other dangerous viruses. This process is done through the use of infected executable files, which in turn will be masquerading as installers for free programs or other files. Even if BSOD Error 333 does not try to install a virus in your computer the installer offered will be nothing but bloatware.

The classic example of the bloatware scam involved first creating a bogus warning about some kind of problem with your computer. A foreign program will claim it scanned your computer for free (without your permission – your first red flag) and that is has found a large number of errors. It will try to sound as scary and dangerous as it can be. You will then be asked to purchase the full version in order for it to work. If you make the mistake of doing that the program will just claim it cleared the problem – but of course such a problem never existed in the first place.

Nothing useful will really come out of BSOD Error 333 really, so hurry up and remove it. Ignore anything that you see coming out of BSOD Error 333 – even if look like system messages. Other common tricks used by BSOD Error 333 include missing plug-ins, required video players or codecs and basically anything else that involved downloading and starting an executable file on your computer.

1: Enter Safe Mode.
2: Remove BSOD Error 333 from Chrome, Firefox, Internet Explorer and Safari.
3: Remove the virus from browser shortcuts.
4: Uninstall the virus from your AddRemove Programs.
5: Permanently remove BSOD Error 333 from Task Manager’s processes.
6: Delete the virus from Regedit and Msconfig.
7: Optimize your PC after the removal is done.

You are now in the Control Panel. Search around for BSOD Error 333 and anything else suspicious-looking. Uninstall it/them. Also, be extremely careful. 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 Uninstallchoose NO:


Hold the Windows Key and R againbut this time copy + paste the following and click OK:

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

A .txt file will open – don’t touch anything there. 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.

Go to STEP 5.


Open the Task Manager by right clicking on the Taskbar and choosing Start Task Manager.


Once it opens, choose 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.


What we have now is likely the most difficult and also potentially dangerous part of the removal guide. It involved the deletion of important files and if mishandled could induce system instability, damage to your OS, other programs or even data loss. For all of these reasons we encourage you to follow the instructions carefully or better yet download a professional anti-malware program that can remove BSOD Error 333 for you – risk free.

Another reason for spending a few bucks on proven anti-malware software is because you can use it for long term protection and the scanner that comes with it can expose some of the most dangerous viruses in existence before they can do any real harm.


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.

Move on to STEP 6.


Take a look at the following things:

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


Go in the Startup tab and Uncheck anything that has “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 the registries manually:

  • HKEY_CURRENT_USER—-Software—–Random numbers
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
