Important Tips!

Recommended Solution

If your computer is infected with malware (computer virus, spyware, rootkit, trojan horse, worm, etc..), and you want to be 100% sure that your system will be clean, then the best solution is to reinstall Windows or that's 100% clean.

Why?

Well, if your antivirus (anti-malware) software detected malware, then you will never know for sure if that's the only piece of malware that has infected your system.

Malware can nestle itself deeper into your system and hide itself, so that it can't be discovered by your security software and it can also open doors to other malware.

Now:

I know that most people don't want to reinstall Windows or don't have a system image backup, so that's why I will show you step by step how to remove malware from your infected PC in a few different ways.

And now continue with removing malware:

Step 1: Enter Safe Mode with Networking

If you think your computer has a malware infection, then boot Windows into "Safe Mode with Networking".

This is important because it helps to remove Malware easier since it's not running and active.

Deleting your temporary files can speed up the scanning process and also free up disk space.

You don't need to install any extra software, because Windows has a built-in tool called "Disk Cleanup".

  1. Open Windows Disk Cleanup.
    • Three ways to open this tool:
      • Go to the Windows searchbar and search for cleanup and click on "Disk Cleanup".
      • Press the Windows + R key on your keyboard, enter cleanmgr.exe, and click on "OK".

  4. Select the type of files you want to delete. I always select everything.
  5. Click on "OK".

This may take a while. The time it takes depends on how many files need to be deleted. When it's finished the tool will close by itself.

Step 3: Full System Scan with Your Antivirus Software

Look:

Your antivirus program may missed the malware that has infected your PC the first time.
