I'm quite angered at this point actually, This is the second point at which I've had to change my passwords due to possibly compromising my passwords and it's quite irritating. I wish the average user would actually learn to use a computer before installing shit on my PC while I'm away...

What exactly are they installing?

Browser add-ons, Lesser known "Free" games that install trojans with them, All that kind of crazy stuff.

Why didn't you restrict their access while you were away?

I'm actually seriously considering that now, I thought they would have been responsible enough to know not to download stuff without asking me first.

You need to either set up user-level accounts for them to use, or just lock down the system so they can't access it without you there. Unless people are willing to take the initiative on their own to learn good security practices user education just doesn't work, so you need to employ technical measures to limit what users can do.

Save money, get a laptop. A $300-$600 will suffice for internet browsing and small gaming.

The laptop is not for you, but for your family member.

I couldn't agree with you more. That's why I have my own PC and I have bought one for everyone else in the family. I do not want my PC touched.

Mobile phone and PC are more and more becoming a part of our "Personal Space."

"Disposable" laptops, netbooks and tablets are now fairly common place; brand new Acer portables now cost as low as $299 in some stores around here, and I've even seen Canadian Tire sell 7-inch capacitive touchscreen tablets with Android ICS for $150. They're all POS of course, but it's something you could give to a relative who just wants to go on YouTube or Facebook, and would otherwise peek into your data or mess up your system.

Oh wow, that bad? what kind of websites your kids visit anyway? I think it's time to install adblock and child restriction software.

I used to know someone who's computer was petty much nickname virus city. They would all ways have a small army of infected things in there.

This. If you just want them on your comp, there's no "fuck you" like drive level TrueCrypt encryption. That's how I told my ex, "Use your own fucking computer, and quit trying to sneak a peak at my stuff, you sneaky bitch!"

That went over just about as well as you'd expect, she's still butt-hurt about it. But if you steal shit or fuck up my stuff, too bad.

She used to try and peak at the password until she realized it was over thirty characters of gibberish.

You can get a pretty decent Acer netbook here in Bangkok for around 300 bucks and they come fully loaded with just about any type of pirated software you could possibly want. The beauty of buying computers in Thailand -- everything on them is pirated, just about anywhere you buy them :)

I bought my last one in Spain. Was quite sad to see all the stuff I'm normally used to didn't come with it, LOL.
