The primary goal of spy ware is to gather information about the computer system’s use. This includes Internet browsing habits, email addresses bank account information, account details, information and other personal details that could be used by hackers to steal identities motives. It may also redirect web search results, alter homepages for browsers and alter computer system settings.
Users can protect themselves from spyware infections by avoiding free downloadable applications, programs, toolbars and add ons that often come with malware. They should read the terms of service and privacy policies of sites before downloading software and avoid clicking buttons in pop-up windows. They should also select the “no” option when a pop-up window asks them if they want to run a program or perform another task.
Antispyware programs can detect and eliminate existing spyware on a mobile or computer device, and make sure it is not infected by new devices. Certain programs offer real-time security that scans all incoming network data, and blocks attempts to install malicious software. They can also prevent spyware from tracking a user’s online activities or recording keystrokes.
The main disadvantage of spyware is that it can slow down a computer and eat up a substantial amount of Internet bandwidth, memory and processing power. It also can cause crashes to applications and cause the computer to overheat. Some spyware programs are able to disguise themselves from antispyware software, and blend into the operating system’s files.
