Remove System Check

What is System Check?

System Check is also known as Smart HDD, S.M.A.R.T. Virus or S.M.A.R.T. Check; all from the exact same malware family Win32/FakeSysdef. It is a bogus software application that creates disturbing redirection errors. Normally you will have the ability to figure out if your computer system is attacked with System Check when you view an error that states "A Major Hard drive Error Writing Drive C: /" alert on your monitor. Likewise, it will remove all your shortcuts and keep them in your temporary folder (% Temp % smtmp), so that none of them will show up on your start menu, this way you will not have the ability to start any sort of application from the start menu, making you assume that your system has significant problems.

This bogus software program is typically from corrupted web sites that you could have visited or from malware software program that you have actually downloaded. System Check will immediately invade your system and will generate untrue alerts and pop ups that state your system has actually been threatened by a major infection or there are hard disk problems identified. It will urge you to stop utilizing the trial version and buy a certified complete version of System Check to activate threat elimination features however once you click "Buy license now" you will put your private as well as financial info at risk.

Some of the System Check fake security alerts and warnings that users may get:
Hard Drive Boot Sector Reading Error During I/O system initialization, the boot device driver might have failed to initialize the boot device. File system initialization might have failed because it did not recognize the data on boot device.
System blocks were not found This is most likely occurred because of hard disk failure. This may also lead to a potential loss of data.

System Check could make use of a TDSS rootkit to shield and disguise its malware data, and to prevent you from starting any kind of anti-malware software application, therefore making itself even more difficult to remove. There are bogus registration codes to stop irritating pop ups however these will never ever get rid of the bogus software application. You have to make use of a reputable anti - malware and anti spyware software application to eliminate this threat. You also have to run a complete system scan to identify any type of damages that System Check has actually created.

Step 2: Disable System Check Proxy Server

System Check may add a proxy to its package. Its goal is to get the information through the Web connection (password etc).
It also helps to block the connection to certain sites (eg malware removal help sites) or to block the download of trustworthy antispyware and antivirus programs.

The following steps reset the Internet Explorer proxy settings in the Windows registry so that you can access the Internet again:

  2. Type in iexplore.exe.
    Run iexplore.exe


Step 3: Remove the System Check rootkit

System Check may be bundled with the TDSS rootkit. A rootkit is a program that hides the presence of malware in the system.
Kaspersky offers a free utility, TDSSKiller, that removes malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon).

So to find out if your system is infected with any rootkits that make System Check hidden and very difficult to remove, follow the steps below:

  1. Download Kaspersky TDSSKiller to your desktop from the following link:
    Kaspersky TDSSKiller Download link

  2. System Check may block all executable files, so when you launch the TDSSKiller file, it will execute itself.
    So Rename tdsskiller.exe to tdsskiller.com or winlogon.exe or iexplore.exe
    Rename tdsskiller.exe

  3. After you run TDSSKiller (or the renamed version), in the welcome screen click on Start Scan.
    Kaspersky TDSSKiller Start Scan

  4. TDSSKiller will now scan your computer.

  5. If any infection was found, TDSSKiller will display a screen results like the following one:

    Then click on the Continue button and TDSSKiller will clean the infections.

  6. A reboot might require after disinfection. In this case, click on Reboot Computer
    Kaspersky TDSSKiller Reboot Computer

  7. After the reboot, start your computer again in Safe Mode with Networking and then disable any System Check Proxy Server (See Step 1&2).


Step 4: Stop System Check processes

In order to stop System Check from interfering with our removal procedure, we need to end and kill its processes. For this, we will use a FREE powerful utility called RogueKiller.

RogueKiller (by Tigzy) is a tool written in C++, which scans the running processes, and kills those which are malicious. This tool was developed based on speed execution, which will clean the running processes before being killed.

To terminate System Check process:

  1. Always in Safe Mode Download RogueKiller to your desktop from the following link:

    RogueKiller Download link
    RogueKiller Setup Icon
    RogueKiller is a portable application, so you don't need to install anything.

  2. System Check may block all executable files, so when you launch the RogueKiller file, it will execute itself. So Rename RogueKiller.exe to RogueKiller.com or winlogon.exe or iexplore.exe

  3. At this point a "pre-scan" will complete and stop any malicious process. Also a list of options will appear along the right-hand side.

Step 5: Remove System Check registry keys

To remove System Check malicious registry entries, we will need RogueKiller again.
RogueKiller also checks for rogue Registry entries, rogue drivers, and Master Boot Record (MBR) issues, so rootkits will be cut.
RogueKiller can also fix and restore a Host file, delete any Proxy entries, repair shortcut problems and unhide files.

CAUTION: This tool is not for beginners. In this step we will ONLY use the Registry tab.

To Delete System Check Registry entries:

  1. Always in Safe Mode run a scan, open RogueKiller and click on Scan.

  2. After a while, you should see a screen with scan results like the following one:
