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.
