Sysenter Hook virus removal

Hello everyone. I’m a new user on this forum. I just would like to seek some help regarding the Sysenter Hook virus which was detected by AVG on my computer. I never installed any program neither download anything on this PC. It suddenly fails to open some programs and the performance suddenly became so sluggish. This is the reason why I run a complete scan of AVG antivirus. To my surprise, it identified a medium threat called “Sysenter Hook”. It cannot be deleted because according to the program, it was part of the operating system.

I did try running other scanners like Norton Power Eraser and Avast. Both found no threats on my computer. I am so confuse about this issue. It seems that no antivirus program may be able to remove Sysenter Hook virus on my computer.

When I posted this issue on another forum, they told me to run various adware and malware scanners like adwcleaner, malwarebytes, and similar tools. All of the scans came up empty. My computer appears to be clean or is it that Sysenter Hook is operating very discretely on my computer.

I really don’t know what to do now. I am not compatible working with a system that I know is infected with Sysenter Hook virus. Please help me.

    Try to use a popular Kaspersky tool called TDSSKiller. It was made to remove dangerous Trojans and Rootkits including Sysenter Hook.

    Anti-rootkit utility called TDSSKiller is a free tool from Kasperksy that neutralizes complicated malware which effectively hides its process, folders, files and registry entries.

    1. Download TDSSKiller from this link. Save the file to your desktop.
    2. Extract the contents using archiver applications.
    3. Reboot the computer in Safe Mode to avoid Sysenter Hook from loading at start-up. You may want to print this procedure as we have to restart the computer to complete the removal process.
    – Restart the computer.
    – Before Windows begins to load, press F8 on your keyboard.
    – It will display an Advanced Boot Options menu. Select Safe Mode with Networking.

    – Windows will now start in Safe Mode.

    4. Locate and run the TDSSKiller.exe file.

    5. On Object to Scan, please mark Services and drivers as well as Boot Sectors.
    6. Click on Start Scan to begin scanning your system. This may take a while.
    7. After the scan is finished, it will reboot the computer. That should complete the disinfection process.
