Computer viruses and spyware have become more and more sophisticated over the years. Even while using caution, your computer can still become infected, especially if it is running a Windows-based operating system.
However, by keeping your anti-virus software updated, avoiding dangerous websites, and being careful about opening email attachments, you are more likely to avoid infection. Here are some common computer viruses and spyware to watch out for.

By downloading all available security updates you can stop this computer virus from infecting your computer.
Spyware is a term for any unwanted program that exploits infected computers for commercial gain.
