A STEP BY STEP GUIDE ON REMOVING A MALWARE ON PC
Virus is a computer program or software designed to disrupt the operations, damage the files, or gain authorized access to a computer system without consent of the user.
COMMON TYPES OF VIRUSES
Malware is a short name for ‘malicious software’. It is designed to cause harm to the system and can perform various functions depending on the type of malware. Some of the types of malware are:
As the name says, these viruses steal the sensitive information of the users. They usually try to hide themselves as much as possible and do not cause any harm that slows down the system. Common activity of spyware comprises of activity monitoring, keystroke collection, altering security settings, collection of sensitive data.
Trojan or Trojan Horse are the programs which disguises itself as the normal program but when installed shows it’s true nature. Trojans also record sensitive information, download more viruses, corrupt files etc.
Adware is a virus that forcibly shows annoying advertisements on your screen. Adware hijacks your browsers and changes their entire settings by adding malicious contents. It also tracks the user behavior and collects sensitive information.
The word is a combination of ‘Ransom + Software’ meaning a program that hijacks the user files and demands money in return. This virus usually encrypts the users’ files which makes impossible for the user to recover the files, locks down the system and displays message on the procedure to recover files. Paying ransom is not recommended as it fuels more attacks.
