Scan and check for viruses and malware

A virus, malware, or other malicious software could cause your PC to run slowly. Some other symptoms include unexpected pop-up messages, programs that unexpectedly start automatically, or the sound of your hard disk constantly working.

The best way to handle viruses and malicious software is to try to prevent them by running anti-malware and anti-virus software and keeping it up to date. Even if you take precautions, your PC can still become infected.
