What is System Fix?

System Fix is a fake computer optimizer that attempts to scare computer users into purchasing a fake license. Like its previous versions (System Restore, Data Restore, Data Repair), this fake optimizer employs various methods to intimidate computer users into believing that their computer hardware components have serious issues and that they could lose their stored information.

System Fix is proliferated through misleading websites able to install this rogue program on users' computers by exploiting security vulnerabilities. When System Fix self-installs on your computer, it floods your desktop with various warning messages reporting that there are critical errors in your computer's RAM, system drive, and system registry.

Furthermore, System Fix hides your desktop icons, reporting that there are bad blocks found on your hard drive surface. Following the scan, if you click the 'Fix Errors' button, you are asked to purchase a full version of System Fix in order to eliminate the 'detected' hardware issues.

Do not buy System Fix - it is a fake optimizer and a useless program created by Internet criminals to trick unsuspecting computer users. The computer scans and security messages regarding hardware malfunctions are fake.

When analyzing this software, we found none of the features required of a genuine system optimizer, thus clearly proving that System Fix is a bogus program unable to identify hardware errors on your PC. Do not panic about your missing desktop icons and start menu items, since System Fix only hides them.

Follow these step-by-step instructions to eliminate this rogue program from your computer and regain control of your hidden files.

System Fix virus removal:

Step 1
Before downloading the spyware remover, enter the System Fix registration key in the registration window. Click on "Click here to activate full-functional version" located on the bottom-left of the main window and enter this key:

E-mail: fake (at) email.com Key: 1203978628012489708290478989147

Step 2
When the registration key is entered, System Fix will behave as if you have purchased it and will stop generating fake warnings. It will also enable some previously disabled Windows features.

Note that registering this program will not remove it from your PC. It will simply disable the fake warnings and enable you to install spyware removers.

After entering this key, you can download the remover (use the button below) and remove this fake security software.

If you cannot download or run the default installation file, you can try to download an alternate installer.


If, after removal of System Fix, your Desktop icons or files remain hidden, complete these steps: 

Step 1
This Infection Hides most user files. If you cannot see your files, do not panic - the files are not missing, simply hidden.

When downloaded, the spyware remover removes the infection. Please download and run this tool to 'unhide' your files (Link below).

It is important to run this tool only when the infection has been removed from your computer. This 'unhide files' tool is useless if run on an infected computer.

When the unhide files tool finishes, your Windows desktop icons may still be hidden. To fix the missing desktop items after spyware infection, download this .REG file.

Double click when downloaded, click yes, and then click OK. Reboot your computer, and your desktop items should now be visible.

Step 2
Reboot your computer to check if everything is OK and that the System Fix rogue spyware is removed. Check if you can find all your files. If, however, some files remain missing, open My Computer, Click Tools, then select Folder Options... and under View tab, select the radio button "Show hidden files and folders", press OK.

You will now see the hidden files and folders. To unhide them, right click on the file or folder, then select Properties and uncheck the "Hidden" Check box.

That's it! You're done.

If you are unable to remove System Fix, you can use these manual removal instructions. Use them at your own risk, since if you do not have strong computer knowledge, you could harm your operating system.

Use them only if you are an experienced computer user. (Instructions on how to end processes, remove registry entries...)

Key: 1203978628012489708290478989147

If it works, the bogus program is disabled and you will be able to remove it without continual interventions. Note, that this infection constantly mutates and the keys may be changed.

After this procedure, you are able to see your files and install a legitimate spyware remover to remove this infection. If the registration key does not work, proceed to Step 3.

Warning! Entering the activation key does not remove this infection! It simply disables the fake warnings. This spyware will run in the background and continue to collect your data!

Step 3
Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK.

During your computer starting process press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, then select Safe Mode with Networking from the list.

Other tools known to remove System Fix:


The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.

A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in fake antivirus distribution:

By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals.
