The spyware agent can be malware (modifies system settings, and can perform undesirable tasks on your system), hijacker (redirects your browser to web sites), dialer (dials a service, most likely porn sites, for which you are billed!), trojan horse (is attached to a program, and performs undesirable tasks on your system), collectware (collects information about you and your surfing habits). In addition to doing a detailed check of your browser history, spyware can install DLLs and other executables files, send continuous data to the parent, leave a backdoor open for hackers to intercept your personal data or enter your computer, can install other programs directly on to your computer without your knowledge, can send/receive cookies to other spyware programs and invite them into your computer (even if you have cookies disabled), and they can add Trojan horses to your system. Most spyware and adware programs are independent executable files which take on the authorization abilities of the victim. They include auto install and auto update capabilities and can report on any attempts to remove or modify them. Spyware programs can reset your auto signature, disable or bypass your uninstall features, monitor your keystrokes, scan files on your drive, access your applications, change homepages in addition to displaying advertising content online or offline. |
