I have been servicing computers since 1980 , have been servicing commercial networks for 16 years . I have 4 pc's in my office Windows 8 , windows 7 , windows xp pro & Linux . The one with xp pro has not ever had a virus or any updates from Microsoft . The updates open a back door access to windows for all the junk to . enter . The key is to go on line when you need to , turn off your connection when you are done .
