Hi forum friends,
You can keep your laptop virus free with avast, protect your browser with script blocking and have all the OS and other software on your machine upgraded and updated. But you also have to fight another mighty enemy, - dust - , once every half a year or so. A bit of compressed air will work just fine. Most at risk might be your graphical card specially if you are into heavy gaming and so it is well worth the trouble if you are nearing temps of 70 degrees after some hours of normal duty. Gone that card may cost you something around 139 bucks, compressed air cost far, far less. I guess if they do the cleansing for you, it will cost you 100 bucks less than that card repair, that is 9,
