What are some common signs of a malware infection on a computer?
There are several common signs that indicate a possible malware infection on a computer. These include a noticeable decrease in system performance, unexpected crashes or freezes, frequent pop-up ads, changes in browser settings or homepage, and unexplained changes in file sizes or file extensions. Other signs may include the presence of unfamiliar programs or files, disabled security software, or unusual network activity.
One sign of a malware infection is the presence of a keylogger, which records every keystroke made on the infected computer. This can include sensitive information such as passwords, credit card numbers, and personal identification information. Another indication is the presence of a backdoor, which allows remote access to the infected system, enabling the attacker to steal confidential data or launch further attacks. Additionally, some malware may encrypt files and demand a ransom for their release, a technique known as ransomware.
