Manual Virus Removal
For advanced users, manual removal is possible; however, it carries risks if you are unsure about what you are deleting.
Steps for Manual Removal
- Open Task Manager (Ctrl + Shift + Esc) and look for suspicious processes. Right-click and select End Task.
- Access the Control Panel and navigate to Programs. Uninstall any unfamiliar applications.
- Search for Malicious Files: Use File Explorer to check system folders like
C:\Users\[YourUser]\AppData\LocalandC:\Program Files. Delete unusual entries.
Preventing Future Virus Infections
Once your laptop is virus-free, the focus should shift to prevention. Here are some effective strategies to protect your HP laptop from future infections.
