To scan for viruses in Windows using PowerShell, you can use the Get-MpComputerStatus cmdlet from the Microsoft.Powershell.Security module, which is part of the built-in Windows Defender antivirus software.
Here is an example of how you can use this cmdlet to scan for viruses:
Import-Module Microsoft.Powershell.Security
$result = Get-MpComputerStatus
if ($result.VirusScanningEnabled -eq $false) {
Write-Output “Virus scanning is disabled. Please enable virus scanning and try again.”
} else {
Write-Output “Virus scanning is enabled. Checking for viruses…”
$scan = Start-MpScan -ScanType CustomScan -ScanPath C:\
Write-Output “Scan in progress. This may take a while.”
while ($scan.IsCompleted -eq $false) {
Start-Sleep -Seconds 5
$scan.Refresh()
}
if ($scan.ThreatsDetected –gt 0) {
Write-Output “Threats detected. Please check the scan results for more information.”
} else {
Write-Output “No threats detected.”
}
}
This code first checks to see if virus scanning is enabled on the system. If it is not, it displays a message asking the user to enable virus scanning. If virus scanning is enabled, the code initiates a custom scan of the C: drive and displays a message indicating that the scan is in progress. The code then waits until the scan is complete, and then checks the number of threats detected. If any threats were detected, it displays a message indicating that threats were found. If no threats were detected, it displays a message saying that the system is clean.
Note that this code will only scan for viruses using Windows Defender. If you want to use a different antivirus software or scan other locations on the system, you will need to modify the code accordingly.
