Windows 10: Is my computer safe after a hacker?

My other computer was hacked with the pop up message from Microsoft, I uninstalled all the apps they told me to download once I found out it was a scam. Is my computer safe? It has been running really slow since then. Should I bring in somewhere? I do a lot of business work on it. Please let me know some steps I can do to make my computer feel safe to do work on again. Thank you.

Cannot Enter Safe Mode / Computer boots normally

I'm running Win 10 Pro 1903.

Here are the steps I have taken to get into safe mode: Start button, settings, update and security, recovery, advanced startup, troubleshoot, advanced options, startup settings, restart. The computer boots normally, not in safe mode. Any suggestions would be most helpful. Thanks in advance for your help and interest. .

 

Need to get hackers off my computer

Hi

Welcome to Microsoft community.

I'm glad to help you.

The Reset PC feature does not completely format the virus, the system local files are still retained.

If you want to get rid of hackers, the first thing you need to do is the following.

• 1. Change a network environment, if you can't change it temporarily, you can use a mobile phone hotspot to provide network for your computer (pay attention to the use of data traffic, check whether your data traffic is enough)
  

• 2. Reformat and install your windows so as to make sure your computer virus is gone.
  

• 3. Change your Microsoft account password, or even enable the 2-step verification feature. For a safer initialization of your computer, I suggest that you do not apply the Microsoft account login for now, but use the offline local administrator account to login your new windows.
  

If you need more help, please don't hesitate to let me know.
