Spyware Monitors Online Transactions And Steals Password
Spyware is malicious software designed to monitor computer activities. Once installed, it gains access to the camera, mic, and browser enabling it to track and record conversations and online transactions.
Because Spyware can lie between the web server and web browser, it can view the details of online searches allowing it to steal passwords and other personal information. By manipulating the mic and camera, it can watch the victim and listen to conversations without being exposed. That is why it is important to check for spyware on the computer.
Spyware is designed not to cause computer glitches, so it can go undetected for a long time because theres usually no warning sign of an infection. The victim will never have a knowledge that spyware is lurking in the computer until the personal details are used for unauthorized transactions.
Spyware transmits the collected information to the hacker. The hacker then can use the information to withdraw money from the bank, make online transactions, and more! If you suspect that a spyware is hiding in the computer, here are some ways to check for spyware.
