It usually gets installed through fake downloads, bundled software, phishing attachments, malicious browser add-ons, or remote access tools left behind after a compromise. In some cases, it may also arrive through a cracked program or a “system optimizer” that is actually malware.
Common Symptoms
- Unknown processes using CPU, memory, or disk activity when you are not doing much
- Browser extensions, apps, or startup items you do not recognize
- Frequent security warnings, disabled antivirus, or blocked security settings
- Unexplained screenshots, clipboard issues, or signs that typed passwords may be exposed
- Slow performance, network activity spikes, or webcam/microphone access without a clear reason
How to Fix It Manually
-
Disconnect the PC from the internet
- Turn off Wi-Fi from the taskbar, or unplug the Ethernet cable.
- This can stop spyware from sending captured keystrokes, screenshots, or clipboard data to a remote server.
-
Check for suspicious processes in Task Manager
- Open Task Manager with
Ctrl + Shift + Esc. - Click More details if needed.
- Look under Processes for unfamiliar apps, especially ones with odd names, high resource usage, or no clear publisher.
- Right-click a suspicious process and choose Open file location. If it points to a strange folder under
AppData,Temp, or an unknown program folder, note it. - If you are confident it is not legitimate, right-click it and select End task.
- Open Task Manager with
-
Review startup programs
- In Task Manager, open the Startup apps tab.
- Disable anything you do not recognize or do not need, especially entries with Unknown publisher.
- Also go to Settings > Apps > Startup and review the same list for anything suspicious.
-
Uninstall suspicious apps and browser extensions
- Open Settings > Apps > Installed apps.
- Sort by Install date and remove anything unfamiliar, recently installed, or clearly unwanted.
- Then check your browser extensions:
- Chrome/Edge: Open the browser, go to Extensions, and remove unknown add-ons.
- Firefox: Open Add-ons and themes and disable or remove anything suspicious.

Run Microsoft Defender scans
- Open Windows Security from the Start menu.
- Go to Virus & threat protection.
- Click Scan options and run a Full scan.

Check remote access and permissions
- Open Settings > System > Remote Desktop and make sure it is Off unless you use it.
- Go to Settings > Privacy & security and review permissions for Microphone, Camera, and Screen capture-related apps where applicable.
- Remove access for apps you do not trust.
-
Change important passwords from a clean device
- If keystrokes may have been captured, assume passwords are exposed.
- Use a different trusted device to change passwords for email, banking, work accounts, and password managers.
- Turn on two-factor authentication wherever possible.
-
Update Windows and security tools
- Go to Settings > Windows Update and install all available updates.
- Restart the PC and run another security scan.
