Thanx god! I don't use Windows anymore

As a Windows user, I was very tempted to try every applications that promised me to keep my Windows fast. Registry cleaners were on top of those applications.Sometimes I stumble upon sites which pops up a window suggesting me to download a software which will make my computer fast. I must admit honestly that I've clicked on those links on several occasions hoping it would do what it said. And it would take me long to realize that I have invited some malwares/spywares instead of speeding up my syste. But now I don't have to worry about all those things and I can simply ignore pop-up like this, because I don't use Windows any more, I've already switched to Ubuntu Linux! Thanx god Linux for keeping my computer healthy (no spyware/malware), wealthy(no eating of my computer resources unnecessarily anymore) and wise (of course Linux is intelligent)!
