What are some common signs that indicate a computer may be infected with malware?

### REPLY:
When a computer is infected with malware, it can lead to various symptoms such as banking details being stolen, personal information being compromised, or even remote control of the infected system by the attacker. The malware may also create backdoors, allowing the attacker to gain full control over the compromised computer and use it for illegal activities such as launching DDoS attacks or distributing spam emails.
