Hi, 1) If I'm using Windows and never download anything but official software from the internet (Firefox browser, etc.), never download any files from spam emails, and never load any harmful files onto the computer, does that theoretically prevent any chance of getting a virus? Are there any other ways to get a virus in Windows? 2) If I go to a secure web page (such as when doing banking, etc.) in Windows, is that just as secure as being on the same page in OSX? 3) If, in addition to the preventative measures in #1, I use the free AVG anti-virus program, will Windows be as secure as OSX? Thanks.
