Signs of a Virus: Strange Noises From the Computer, Such as Excessive Fan Noise
Excessive computer fan noise often indicates a potential malware infection, as malicious programs can cause high processor usage that requires increased cooling. While normal fan activity occurs during resource-intensive tasks like gaming, constant high speeds during basic operations may signal security threats. Users should monitor for unexplained fan behaviour during idle periods and investigate using antivirus software. Regular system maintenance, including cleaning vents and monitoring temperatures, helps distinguish between mechanical issues and security concerns. Further investigation reveals additional warning signs of malware presence.
