If your device has gotten a virus or malware infection, there are some telltale signs, including:

• Reduced Speed: Your device slows down significantly.
• Pop-ups: You have started to see a lot of unexpected pop-ups.
• System crashing: Your system unexpectedly crashes, either by freezing or by giving you a blue screen.
• Loss of disk space: A lot of your device’s storage has been taken up unexpectedly.
• Settings changed: Device or browser settings change without you changing them.
• Files encrypted: Ransomware has locked you out of your files or your entire device.

Different types of malware use your device’s resources in different ways, such as making it part of a botnet to perform DDoS attacks, mining cryptocurrency without your knowledge, or other nefarious activities.

If you suspect your device may be infected with a virus or malware, download our free malware scanner and run a free scan to find and quarantine any malware on your device.
