  • Restart the laptop.
  • Press the F8 key repeatedly before the Windows logo appears.
  • Select “Safe Mode with Networking” from the Advanced Boot Options menu.

Once in Safe Mode, open the Task Manager (Ctrl + Shift + Esc) and look for unfamiliar or suspicious processes consuming high resources. Research these processes online to determine if they are malicious.

Next, navigate to the following locations to check for unknown startup programs and suspicious files:

  • Startup folders (`shell:startup` via Run dialog)
  • System configuration utility (`msconfig`)
  • Program Files and AppData directories

Delete any files or uninstall programs that are confirmed to be malware. Be cautious not to remove essential system files.

Using Windows Defender Offline Scan

Windows Defender includes an Offline Scan feature that can detect and remove rootkits and other deeply embedded malware that standard scans might miss. This tool runs outside of the normal Windows environment, increasing its effectiveness.

To run a Windows Defender Offline Scan on your HP laptop:

  • Open Windows Security from the Start menu.
  • Go to “Virus & threat protection.”
  • Under “Current threats,” select “Scan options.”
  • Choose “Windows Defender Offline scan” and click “Scan now.”
  • Your laptop will restart and perform a scan before loading Windows.

The scan typically takes 15-30 minutes. After completion, Windows will start normally and display the scan results.

System Restore as a Virus Removal Option

If viruses have caused significant system instability, using System Restore can revert your laptop to a previous state before infection. This method does not affect personal files but will remove recently installed programs and drivers.

To use System Restore on an HP laptop:

  • Open Control Panel and navigate to “Recovery.”
  • Select “Open System Restore.”
  • Choose a restore point dated before the virus infection.
  • Follow the prompts to restore your system.

Be aware that this method only works if restore points were created before the infection occurred.
