There are a few things that users can do to help prevent spyware from infecting their computers. One of the most important things to do is to keep all software up to date. This includes not only the operating system, but also all applications installed on the computer. Spyware authors often exploit vulnerabilities in outdated software to install their malicious programs onto a victim’s machine.
Another helpful measure is to use a quality antivirus program and keep it up to date. Antivirus software can detect and remove many types of spyware; however, it is important to remember that no program is 100% effective. In addition, some spyware programs are designed to disable or interfere with anti-spyware tools, making them more difficult to detect and remove.
Users should also be cautious when downloading files from the internet, as spyware can be bundled with seemingly innocuous downloads. It is always best to download files from reputable sources and avoid clicking on links in email messages or instant messages from unknown sender.
