A computer virus is a type of malware that, when executed, perform various harmful and/or disturbing activities such as wasting hard disk space or using CPU time, accessing private information and sending it through the network to a remote computer, corrupting data, or displaying obscene messages. Computer viruses often replicate themselves on the local computer or other computers through the network. Some viruses, such as macro viruses, attack Office files rather than the operating system, while others target emails and are able to spam your contacts from your mailbox. Those malware software that log the user’s keystrokes might be very dangerous when it comes to sensitive information such as identifiers and password used for online banking (more and more banks apply the combination of keystrokes and mouse clicks for logging in to eliminate unauthorized access when the keystrokes are logged without the user’s consent).
Trojan horses (or trojans for short) are computer programs that appear to be free, useful tools, but in reality they are harmful. Trojans are hacking programs that belong to the non-self-replicating type of malware. They try to gain privileged access to the operating system while appearing to perform a desirable function while dropping a malicious payload instead, often using a backdoor that makes the unauthorized access to the target’s computer possible.
While not all viruses carry a destructive payload or attempt to hide themselves, it is imperative to have proper security settings and software.
