AV is only about 40-60% effective, so no it's not generally enough especially after an infection. Lots of malware are able to defeat AV scanners, so yes I would scan in safe mode. Also malware can affect a system in many ways including corrupting system files, so the system instability could be due to the after affect of the infection.
I had windows 10 pre-installed. (Home edition..) Device manager says drivers are working properly. I think I need to reset my PC...Hi there,
Recovering from virus/malware infections is very similar to recovering from problems due to Microsoft weekly or monthly updates. Common problems due to virus removal are disabling or corruption of drivers for audio (sound), video (graphics), and network adapters (Internet connection).
Make sure you test your hardware using these 2 links:
MEMORY DIAGNOSTICS:
Link Removed
HARD DRIVE DIAGNOSTICS:
Link Removed
Testing your hardware is especially important if you have an older computer and it did not come from the factory with Windows10 pre-loaded on it, such as a computer with Win7/Win8x installed. These computers can be up to 9 years old now as Win7 computers came out in 2009 and hardware failures often begin after systems are 5 years old.
Once tested, I suggest you take a look at my instructions on this link with regard to another W10 user whose audio failed. The questions on his hardware specs and the recommended solutions are covered in my POST #3. Here's the link: Sound Problems
Testing you hardware, once done, allows you to pursue software solutions I discuss such as System Restore and Windows reset/reinstallation. These are of course much more time consuming and more complex than many home users can handle. Many of our forum users have good success with these procedures followed in the order I recommend. Read through this post and my linked post and give it a try. I've found that these procedures result in success about 90% of the time.
Post back your specs, and or SPECCY file and let us know how it goes. Please don't hesitate to ask questions along the way if you get stuck. We are here 24x7x365.
Best of luck,

Foreach($dir in $(Get-ChildItem "C:\Program Files\WindowsApps")) { if ($(Test-Path -Path "$($dir.FullName)\AppxManifest.xml")) { Add-AppxPackage -Path "$($dir.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode } }
Foreach($dir in $(Get-ChildItem "C:\Windows\SystemApps")) { if ($(Test-Path -Path "$($dir.FullName)\AppxManifest.xml")) { Add-AppxPackage -Path "$($dir.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode } }
You can install all the Windows apps with the following commands. You will need to open an elevated powershell prompt.
Code:Foreach($dir in $(Get-ChildItem "C:\Program Files\WindowsApps")) { if ($(Test-Path -Path "$($dir.FullName)\AppxManifest.xml")) { Add-AppxPackage -Path "$($dir.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode } } Foreach($dir in $(Get-ChildItem "C:\Windows\WindowsApps")) { if ($(Test-Path -Path "$($dir.FullName)\AppxManifest.xml")) { Add-AppxPackage -Path "$($dir.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode } }
Foreach($dir in $(Get-ChildItem "C:\Windows\SystemApps")) { if ($(Test-Path -Path "$($dir.FullName)\AppxManifest.xml")) { Add-AppxPackage -Path "$($dir.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode } }
Oops change the path in the command to "C:\Windows\SystemApps"
This one may give you errors if any of them are already installed which most should be.
Code:Foreach($dir in $(Get-ChildItem "C:\Windows\SystemApps")) { if ($(Test-Path -Path "$($dir.FullName)\AppxManifest.xml")) { Add-AppxPackage -Path "$($dir.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode } }
That error is normal, Cortana won't normally install, plus it's probably already there. The first command should have installed the store etc. Most likely the malware damaged the apps, so you may need to reinstall Windows to fix the issues.
If the apps aren't being installed it's usually due to corrupted W10 install media or failed hardware.Did you test your hardware using the diagnostics I gave you links for in my Post #6 above yet? Did you buy or make your own W10 install media? Did it come with your computer when you bought it? If you made your own W10 source, where did you download the ISO file from? Was it from a site other than Microsoft?
Either or both of these problems can cause the symptom you are having.Test you hardware, and post back answers to my questions about your W10 install media, and we'll advise you further. Whatever you have done, you either didn't install W10 from good source or you have failed hardware in that computer which you haven't found and replaced yet since you haven't tested it yet!! Clearly you have done something wrong at this point, or you haven't finished the troubleshooting we recommended to you. Following are guidelines will help you to resolve this problem and get you going again.

d my PC..it remains genuine.
A reset and re-install are not the same. A reset will for the most part restore settings, but it will not fix corruption whether it's due to a malware infection or hardware failures.
