I am a real computer dunce, but since I am traveling I must have a laptop (I write, Skype, etc.). As advised I downloaded free AVG, but I'm confused about updates (download vs how much memory should I be using), and I also see 'virus removal tools', goes on and on, and don't know which of ALL OF THIS I should be downloading. (NOTE: for whatever reason I seem to get virus or other weird problems pretty easily. I don't do anything weird - go on a lot of weird sites or anything - and am terrified of virus's/trojans (found folders once with all the valuable contents MISSING). Maybe it has to do with traveling? Going from country to country and hacker places (?) like Serbia and Egypt. Thanks for any advice about what's important to download. Otherwise my fears and my instincts tell me to download EVERYTHING!
