Spyware is a type of malicious software designed to gather sensitive information from a computer system without the user’s knowledge or consent. This information can include personal information such as passwords, credit card numbers, and online browsing habits, as well as system information such as installed software and hardware specifications. Spyware can be installed on a computer through a variety of means, such as email attachments, infected websites, and bundled software. Some spyware is designed to monitor a user’s activities for advertising purposes, while others are used for more malicious purposes such as identity theft and financial fraud. Spyware can cause a number of problems for a computer user, including decreased system performance, slow internet speeds, and a loss of privacy. It is important to protect your computer from spyware by using anti-virus software and avoiding downloading suspicious files from the internet.
