Missing .Sys File Leading To Vista Ultimate Boot Up Failure

» I believe my boot up has been stricken with a virus....PC won't boot up in Vista Ultimate as it states that I'm missing \windows\system32\drivers\jvbmg.sys. I can't get to command prompt or anything. I was clearing off virus infection when this occurred. what can I do?


Best Answer

» Generally speaking, jvbmg.sys error can be caused by the dll file being deleted accidentally from your system; falsely used due to virus (Worm:Win32/Autorun.AFV) or spyware infection; related registry entries being corrupted.

When jvbmg.sys file error occurs, system performance becomes very slow and awkward; Program and system crash; Computer often freezes up. Programs fail to install or uninstall.

Firstly run a complete antivirus scan, and then clean up the registry. Then you need to remove jvbmg.sys virus infection related problems, just because many associated dll files have been affected in the process of virus infection removal, so we have to do the follows:

Download DLL Suite, install and run > Click Dashboard menu and > Click Scan DLL Errors button > Click Fix DLL Errors button after the scan. DLL Suite can be used to fix any problem of sys files, which is one of three kinds of dll file.

The error message appears as the result of the 'hook' not finding the file - so you need to find the hook. The easiest way is to use MSCONFIG. Can you boot to Safe Mode??

    If so then go to Start then type MSCONFIG in the Search box, and hit the Enter key. Then click on the Startup tab.

    Look for any entry there that either points at the file directly, or is not obviously a 'good' entry - disable all found, and click OK. Boot back to Normal Mode.

MUHAMMAD BILAL replied on January 12, 2013: » If you need to check for malware here are my recommendations - these will allow you to do a thorough check and removal without ending up with a load of spyware programs running resident which can cause as many issues as the malware and maybe harder to detect as the cause.

    No program can be relied upon to detect and remove all malware. Added that often easy to detect malware is often accompanied by a much harder to detect and remove payload. So its better to be overly thorough now than to pay the high price later. Check with these to an extreme overkill point and then run the cleanup only when you are very sure the system is clean.

    These can be done in Safe Mode - repeatedly tap F8 as you boot however you should also run them in regular Windows when you can. Download Hit Malware and scan with it.

Ran repair again....this time no bugcheck and it did find the corrupt file titled...jvbmg.sys says it's corrupt. Attempted to fix file...failed Error Code = 0X2.

    Could I just upgrade this thing to Windows 7 and forget this nonsense? Would that work with it not booting?

  4. WILLIAM KNIGHT replied on January 17, 2013: » The worst time to do an upgrade is when you are having problems. In that situation an upgrade is more likely to worsen the problems than to solve them. You could clean install Windows 7 and that would solve just about any problems but hardware one, but that means that you would lose all your files on the drive and would also have to reinstall all your programs. Do that only if you have a backup of everything important to you.

JEAN GUICHENEY replied on January 18, 2013: » I FIXED IT!!!!! ok here's the deal: using vista restore, go to command prompt and using old school dos knowledge, did a directory search in the windows/system32/drivers directory and found my problematic file ....weird thing is that is had no K associated with it...so one del jvbmg.sys keystroke later, we have lift off.
