Remove Serious System Error

You can only stop the "Serious System Error" pop-up by removing the malware that is causing it to appear. Use only valid security program to scan the PC for harmful files and data.

“Serious System Error” is a fake pop-up alert issued when a malicious file from an infected web site is executed. This will trigger a download of rogue security software on the visitor’s computer. After silent installation of the program, it will require a reboot of the computer and will pretend as a genuine system error for Windows.

Malware authors are trying to mimic Windows alerts and pop-up messages to let user get involved in the execution of viruses.

“System Has Recovered from a Serious Error”
The problem arises after the system writes a bad Minidump file. These Minidump crashes are a result of various code corruption or faulty memory. On some instances, faulty hardware (memory, mother board, video card, power supply unit) also causes this problem.

“serious error”
Computer may automatically restart and you will receive a message “serious error” or “stop error.” This symptom may differ based on the failure detected on the operating system.

    I tried to do as described above, but the computer keeps shutting down before Malwayre has time to finish scanning. I already have it on my computer so don’t have to download it. I am unable to connect to the internet. It finds at least 2 viruses, but is logged off before I can do anything with them or before it finishes scanning. Any suggestions?

    In my case, I found out HDDDOCTOR.EXE was being executed in
    HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon”
    (Shell = %userprofile%\appdata\romaing\hdddoctor.exe)

    It looks like a ‘variant’ of the malware so it vexes the removal tool.

    Here’s what I did:

    verify that it’s running HDDDOCTOR.EXE

    (from the command prompt: CMD)
    REG QUERY “HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon”
    (see the value for Shell and it tells you the location of the file)

    I then removed the entry from the registry

    REG DELETE “HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon” /v Shell

    System is now rebootable without the malware running.

    However, to get rid of HDDDOCTOR.EXE, I had to boot the Windows 7 boot cd, go into repair mode, and manually delete the file using the command prompt there.

    Your variant could be different from mine. The idea is to find the registry entry where HDDDOCTOR.EXE is run. A location to check would be HKCU\Software\Microsoft\Windows\Currentversion\Run

    Good luck
