SAntivirus

Midknyte, sorry for the delay in my reply. The Avast forum didn't really have any solutions, either. They told me to run the Avast removal tool, which I told them I already ran. Since I can't install the Bitdefender AV free version, I came across another free AV called Virustotal. Do you know if that is a good AV?

Virustotal is an online scanner only. You send individual files to be scanned after you suspect they may be infected. Not a substitute for an installed program.

At this point, you should probably create a new thread in the ICU. Maybe Broni will see something that needs to be cleaned out.

The original problem was Segurazo, but now you can't fully uninstall Avast in order to install BitDefender. Maybe he'll have a better suggestion for AV also.

If all else fails, you still have Windows Defender.

[JLS]

Fink, thanks, I wasn't aware that it is not an AV.

Midknyte, I will think about posting in the ICU. In the meantime, I will use Windows Defender. If you use it, it can't be bad. I just searched for windows defender on my laptop. There were several listed (Windows Security or Virus and Threat Protection). Which one is it? Also, I just started uising a paid version of VPN. Do I still need to use an AV?

[Midknyte]

There is only one Windows Defender. The settings are under Windows Security > Virus & Threat Protection.

Yes, you still need to use an AV with a VPN.

Midknyte, I just did a full scan with Defender and it came out clean. My CPU usage during the scan was 100% and computer was very slow that I couldn't even use it during the scan. I could use my computer without any lagness when I used Bitdefender trial version and Avast.

Here are a few things to try:

In the second link on how to limit CPU usage on windows 10, she says in the video that default setting it 50. I entered "Set -MpPreference -ScanAvgCPULoadFactor" in powershell. How do I know it is set to 50 after entering that command like you says in the video?

[Midknyte]

There shouldn't be a space after "Set":
Set-MpPreference -ScanAvgCPULoadFactor 50

To verify the setting, you'd use "Get" instead of "Set":
$Preferences = Get-MpPreference
$Preferences.ScanAvgCPULoadFactor

The first command gets the preferences, and then stores them in the $Preferences variable.
The second command displays the ScanAvgCPULoadFactor property.

[JLS]

I typed Get-MpPreference and scrolled through the list to ScanAvgCPULoadFactor and it was set to the default of 50. I don't know how to change it. I tried the command Set-MpPreference-ScanAvgCPULoadFactor 40 and it gave an error. How do I change it to 40?

Btw, my CPU is only at 100% capacity when I run the Microsoft Defender full scan. My CPU is not really impacted that much when I run the quick scan.

[Midknyte]

Are you copying and pasting the commands? You need to have a space after Set-MpPreference

Set-MpPreference -ScanAvgCPULoadFactor 40

[JLS]

It worked now. I thought the space after "MypPreference" was needed because when I started to type "-ScanAvgCPULoadFactor", it wasn't in bold, so I assumed the space wasn't needed. <my bad>

I tried 3 difference settings (40, 30, 20). All 3 settings still overload my CPU at 100%. How low of that setting can I set it?

[Midknyte]

You probably can't go much lower than 25%. 0 = full CPU

Did you also exclude the Windows Defender folder? That's another suggestion in the links I posted.

[JLS]

I just excluded C:\program files\windows defender folder, and ran Defender at 3 different settings (50,40,30) and CPU was still at 100% capacity.

[Midknyte]

It's weird that it's using 100% CPU, even with the default 50. You're sure it's MsMpEng.exe taking 100%?

Again, there might be some gremlins on your system, so a run through the ICU might help.
