Frequently Asked Questions

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

  • Slow: Your computer 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 (also known as a Blue Screen of Death or BSOD).
  • 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 computer.

Malware can slow down your computer, and an unusually slow computer may be a symptom that it is infected. Different types of malware use your computer’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.

To keep your device protected after your initial malware scan and removal, we recommend Malwarebytes Premium for Windows and Mac, and our mobile security apps on Android and iOS.
