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.
