Join Lisa Bock for an in-depth discussion in this video Protecting your system from spyware, part of IT Security Foundations: Core Concepts.
- Spyware, it's also called adware, tracks information on a user's viewing habits while on the internet, and then sends that information to a remote computer without the user's knowledge. Here I am surfing the internet, and I go onto some sites and I want to maybe download some games, free trials, or other interesting utilities. When prompted to install a program, it comes up with "Do you want to install this program?" and I say "Yes", but meanwhile, the spyware opens up a port on my computer and then it sends information to the mothership, browsing habits, and then possibly other information, such as credit card information.
Spyware is technically not illegal, but an unwanted program, nonetheless. There may be times when you get a new computer and you begin surfing the internet without using any anti-virus or any anti-malware protection. You may soon suspect that you've gotten spyware or a virus. Well, there is help. You could go to the Microsoft Safety Scanner by searching "microsoft safety scanner".
It's a free, downloadable security tool. It helps to remove viruses, spyware, and other malicious software. It's not a replacement for using an anti-virus or anti-malware program.
