Where do spyware programs come from?
Spyware typically comes from two sources. The first is from file sharing programs or other kinds of freeware programs. The second is from browser based software installations. The moral is be careful with what you install. Always read the EULA (end user license agreement) before installing any software. This is usually around the second screen given to you with freeware and file sharing program installations. For browser based software, check the website associated with the software for its EULA and terms of agreement. If you are not clear on certain parts of the EULA, contact the software developer via their phone number or email address.
