When a computer is infected with malware, there are various signs that can indicate the presence of malicious software. One common sign is a significant decrease in system performance, as the malware consumes system resources. Another sign is frequent crashes or system errors, which may occur due to the interference of the malware with critical system processes. Additionally, users may notice unusual network activity, such as excessive data transfers or connections to unfamiliar IP addresses. Pop-up ads can also be a sign of malware, especially if they appear frequently and are difficult to close. Furthermore, changes in browser settings, disabled security software, and unauthorized access to personal information can all indicate a malware infection.
