Manual

How to manually remove Knockit.a guide. Only for ADVANCED users.

  • Step 1: Basic check for Knockit.a activity

    Check running processes on your system. Usually you can find Knockit.a process running. Use the Ctrl+Shift+Esc buttons combination to open system information window and click Processes tab. Scroll down the whole list and try to find the process named like Knockit.a. If you find Knockit.a process running, right click on it and choose “End Process”. It will disable Knockit.a for the current Windows session, but remember that if you do not completely remove Knockit.a using next steps, then your PC will stay vulnerable to malware attack. Next steps are much more important in removing Knockit.a.

  • Step 2: Disconnect your PC from the Internet

    Prevent the malware from leaking or spreading your personal data. Adware usually uses the Internet to transfer all possible and important information you have. Some Adwares are not so “Active” and they can simply disable some Windows features and options. To disconnect your PC from the Internet you need to plug-off LAN cable (if you use LAN connection) or to turn of the Wi-Fi module (if you use Wi-Fi Internet connection). Most of (not 100%) Adwares can not access Wi-Fi module preferences. Turning off the Internet will disable Knockit.a from transferring any data from your PC.

  • Step 3: Enter the safe mode.

    The next step is very important in removing Knockit.a. After turning off the Internet and disabling Knockit.a process you will need to reboot your PC in so-called Safe Mode. Safe Mode is a Windows mode which allows you to start the System using only important applications and services. Safe Mode does not usually allow Knockit.a to load when the system boots (!!!but exceptions can appear!!!). Choose Restart in Windows Start menu and wait until the screen turns off.

    After that you have to follow the next instructions according to the versions of Microsoft Windows you use:

      Windows XP:
    1. Press the F8 key repeatedly when the first screen appears.

    2. Select Safe Mode from Windows Advanced Options Menu and press ENTER.

      Windows Vista, 7:
    1. Press the F8 key repeatedly when the first screen appears.

    2. Use the arrow keys from Windows Advanced Options Menu in order to select Safe Mode and press ENTER.

      Windows 8, 8.1, 10:
    1. Press and hold the Shift button when left-clicking the Restart button on Windows log-on screen.

    2. Select Safe Mode from Windows Troubleshooting boot screen and press ENTER.

  • Step 4: Removing virus files

    Having booted your PC in Safe mode you have to start cleaning your PC manually by deleting every file associated with Knockit.a one by one. Here is the list of all files associated with Knockit.a. Delete all files listed below using the Shift+Delete buttons combination. Always double check the file name as sometimes Adwares use very similar filenames as very important system files do and you can mistakenly remove important system file what will harm your system and you will not be able to boot your PC at all.

    Please, remember that viruses are always progressing and sometimes new files can appear. If you are using our offline PDF guide on How to remove Knockit.a, please check if you have it’s latest version.

    We do not guarantee that Knockit.a has the same file structure at the moment of deleting.

    After removing all files associated with Knockit.a that were listed above, reboot your system in normal mode and check if your PC works fine or you still have any troubles.

    It it is OK – congratulations! You have made a great job!

    If it is still NOT ok – use OSHI Defender to check your PC.
