Often people use the term “Virus” for any suspicious behaviour on their computer. Here we explain some of terms used by professionals in easy way:

♦ Malicious Software: any small software including viruses, Trojans, adware, keyloggers or other harmful software to damage or destroy user’s data or stealing sensitive information from computers called Malicious Software.

♦ Viruses and Worms: viruses require an active program or an infected operating system run and infect other software and documents but worms are stand-alone malicious software that can self-replicate and spread in networks, without any help.

♦ Trojans: is a type of malware that is often disguised as legitimate software. It is used to hack into a computer by misleading users of its true intent. Users are typically tricked into loading and executing Trojans on their systems. Once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system.

♦ Keyloggers: a small software to record every keystroke made by users, especially in order to gain fraudulent access to passwords and other confidential information.

♦ Adware:Adware is a software that displays unwanted ads when a user is online. It collects marketing data without the user’s knowledge or redirects search requests to certain advertising websites.

♦ Spams and Fishing: spam is a junk mail sent in mass to users. It can potentially be very dangerous if it is part of a larger phishing scam. Phishing scams are usually acting as legitimate companies or organizations in order to obtain sensitive information such as passwords and login credentials.
