I have come to find out that my roommate is using my laptop when I am not around. I wouldn't mind, but he recently got a virus on it and I had to spend hours cleaning it. Is there a way for me to password protect my laptop so that he cannot access it? I've asked him not to use it but I can tell he is still doing so. Thanks for your help.

I think my anti-virus software is preventing my iPod from being recognized by iTunes. I don't want to remove the anti-virus software for obvious reasons, but is there anything I can do so that I can properly use this? I think there is a way to temporarily disable the anti-virus? Thanks for your help.

Hello! I have always looked at big systems like Google, Facebook etc and always wondered how they store so much data in such an efficient manner. Storing data is jus one aspect, keeping it secure, I think it is more important than anything else. I don't know but I really want to know how Facebook stores all the passwords of their users in a database. I mean their should be some dedicated database or something like that which is fully secured and where all the passwords are stored and retrieved all the time, right? Can someone elaborate more about how Facebook stores and used the passwords of its users?

Hello! Lately I have noticed that there are a lot of files in my computer that I don't use very often but which are still very important to me. I wanted to enhance their security so I was thinking of encryption. Will it help? Which software should I use? People usually say that if you don't know much about encryption its better not to use it, so should I do it? Does encryption compress a file as well?

Hello! I am a Windows 7 user and my anti-virus subscription just expired. For some odd reasons I could not subscribe to the anti-virus again so for that reason my computer kept on displaying this message that I should enhance my security "Your computer might be at risk" I knew that expired anti-virus was of no use and I came across windows defender. It was an older version so I just updated it from the internet and it has been working fine till this date. My question is if windows defender is as good as any other anti-virus, does it protect my computer the same way like the anti-viruses?

Hello, I am a father of 2 tech savvy teenagers. They have gotten really good at discovering the Windows Admin password, the WiFi password and even my email and Facebook password. Is there a way to stop them from discovering them? I tried changing the passwords periodically, but they seem to know the new ones right away…

My Android tablet caught a Trojan, so the first thing I did was resetting its factory settings, in the hope that it would be deleted. How can I know for sure that the Trojan is gone? Now I am concerned about my other devices attached to the same WiFi network as the Android tablet. Are they at risk? Do I need to change the password and/or other things?
