Malicious software allows attackers to gain remote unauthorized access to other people’s devices. They can disable the computer, damage or delete files, steal personal information (for example, read the password from the keyboard) or use the gadget for selfish purposes (for example, send spam). Malware can be divided into three groups: viruses, network worms, and Trojans. Self-copying malware or viruses proliferate swiftly and may go unreported by the user. This type of malware infects and even deletes data, consumes system resources, and leads to computer issues. Malicious malware known as network worms propagates over the Web area networks. They proliferate quickly and operate invisibly from the infected computer’s user. For instance, they may send malicious messages to everyone in the mail program’s address book, or they might set up a bot to distribute spam or mine cryptocurrency. Trojans may be defined as dangerous software that masquerades as benign or even beneficial applications.
In order to protect a computer, one should do the following. You don’t need to open any attachments from unknown senders. Suspicious letters should be deleted immediately. It is imperative to enable the extensions display mode in the system. Malicious files are often disguised as ordinary graphics, audio, and video files. One must enable a complete ban on receiving emails with executable attachments (Cardona, 2021). Then, it is not appropriate to disable the watchdog programs that are included in the antivirus. They are usually launched when the computer boots up and monitors the actions of programs, blocking unwanted actions and requests to the system. It is also crucial to check the downloaded files with an antivirus. The entire system should be scanned regularly to prevent infection (AG Rob Bonta, n.d.) Finally, it is essential to make sure that one has the most recent versions of a browser and antivirus installed.
