I received the below by email and I thought I'd pass it on. It's not a direct copy and paste - I have edited it a bit to keep the sender's identity confidential.
I strongly suggest that everyone:I have a brand new computer with new virus software, firewalls etc. and I really have concerns about peolpe posting password protected files.
When I tried getting some of these levels my computer went crazy - to the point that everything locked up so I had to completely shut it off, updated and ran all my protection software. I realize that the kids today are learning a great deal about computers but he just doesn't talk as if he knows what this is all about and I was afraid to post this message on the forum since I'm concerned about someone being able to get into a system and keep track of where, what, when etc. Call me paranoid but all my experience with computers I have never had an alert telling me that someone was stopped trying to hijack my computer.
My whole system locked up and things started happening with my system that just wasn't normal. I didn't know how to get this message to all without posting that there maybe a computer geak behind this getting into others systems. And if I am totally out of wack then I truly am sorry but I am concerned for all that are here really enjoying the game/chat and I don't want to see anything or anyone ruin this.
I know people are tracing IP addresses more and more and I just wondered if he has infected computers with either a virus and/or tracking devices. I truly am not a fruitcake, like I said earlier maybe just paranoid abit but if it doesn't sound so far fetched please forward this message so that others can be cautious.
* keeps their protective software up to date (anti-virus, anti-spyware, anti ad-ware, firewall)
* runs regular scans of their entire computer with all "anti-programmes"
* scans files before they are uploaded (especially .zip's) to make sure that a virus is not unintentionally being uploaded as well
* scans files (especially .zip's) before opening them to make sure they are not infected
I am not looking to blame anyone by posting this. I'm only looking to warn you all that you have to be careful for the sake of everybody here. I would hate to see the forum destroyed because people got too affraid to download levels due to spreading virus attacks.
Let's face it: This is the internet and some weird psycho might think it's funny to see if he can destroy other people's computers and the fun of the forum.
So please don't take this the wrong way and most importantly: Please help everybody keeping their computers safe by making sure your own computer is not infected with anything.
Thanks for reading
