Clicking shady ads can also cause computer infections.

How to avoid installation of malware?

Regularly update the operating system and installed programs with the latest security patches and updates. Download software from official websites (or stores) and avoid using P2P networks or other untrustworthy sources for downloading files and programs. Use a reliable antivirus solution.

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer.

To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
