I've been running Windows boxes for years and have had my share of problems with them. I've had numerous problems with Malware infections, especially those browser hijack programs like "Windows Security 2011" and the like. They install themselves on your computer and they want a kings ransom payment as blackmail to allow you to use your own computer. I'm still running Windows XP and my techie friend says that I MUST upgrade to Windows 7 as soon as I can swing the money. My computer hardware is too dated to run Windows 7 so that means a new computer, which I can't afford. Oh joy.
