>Any software you install makes you a bit more vulnerable. AV engines are no exceptions. Just the opposite. The only time I've ever gotten a (disruptive) computer virus was after installing Norton Antivirus. These days my goal is to ensure that I can quickly reformat and reinstall my system. I keep records of what I've installed and how I configure it. Antivirus software is usually either dangerous, not worth paying for, or basically malware. How much anti-virus software is just resource-hogging, popup-spamming adware? No thanks.
