View Full Version : Need help with PC security...

Ok, to start off I'd like to say that me, and my family, have very little knowledge of computers.

Earlier on today, my brother was playing on Battle.net with the firewall down (it needs to be to let him play, for some reason). For some reason, it started screwing up, and he reset the computer. When it came back on, it got as far as the desktop. Then, when we tried to connect to broadband, it wouldn't respond. It was the same with everything else. We tried a few times, and then just decided to leave it for a couple of hours.

After those couple of hours, it worked. Perfectly. Only thing was, something had got onto our pc. There was a shortcut on our desktop to "Derbiz", and when we got onto the internet, it had replaced Wanadoo home as our homepage. And now, I got on here about ten minutes ago, and there have been 6 popups so far. I do not like the look of this!

So, I need some help! What's happening? Is there spyware or something on the computer? How can we get rid of it?

That sounds like Spy/Adware.

I recommend ALL of the following:

AdAware (http://www.lavasoftusa.com/software/adaware/)

Spybot (http://www.safer-networking.org/en/index.html)

Spysweeper (http://www.webroot.com/) You have to get a subscription in order to keep this one updated which costs money but its the best IMO.

FireFox (http://www.mozilla.org/products/firefox/) I assume you are using Internet Explorer, if so then download this. Its a new browser and does a pretty good job of protecting against it. However, some websites won't function properly when you use it, and you will need Internet Explorer. If you have a subscription to Spy Sweeper the protection it provides is better than FireFox and you can run Internet Explorer safely though.

And finally if none of that works:

HiJack This (http://www.majorgeeks.com/download3155.html)

Read what it says on that site carefully though. It should be your last line of defense because you can severely screw up your computer if you don't know what you are doing. For 99% of computer users out there (including me) you should go to a computer help board and post the log file from it there and they will tell you what you need to do to get rid of spyware and such.

EDIT: And also, it is possible to play on Battle.net with a firewall up. Basically you just need to open up the ports that Battle.net uses (I forgot what they are, you can find how to do this at the battle.net website). If you are on a router then it is a bit more difficult to do though but since it apparently worked for your brother by just turning off the firewall I assume you aren't using one (or at least not one with its own firewall).

There's no reason why you shouldn't be able to use b-net from behind a firewall.

This is the one I'm currently using


It's free for personal use, pretty simple to use and seems to provide all the protection you'll need.

Also get the programs that the poster above me suggested. If nothing else get a new browser and at least spybot. Firefox or Opera would be my picks IE is the worst kind of ****. Hijack this can potentially burn a novice so even though it's an awesoem tool I'd steer clear of it for the time being. You're going to be horrified enough by the number of things spybot finds I think.

Since you were running with the firewall down I'd also suggest a virus scan from these people asap to kill any of the trojans and assorted other fun you no doubt picked up in the interval.


When you have broadband you pretty much have to always run a firewall and a virus scanner. You should also download all the relevant security updates from microsoft windows update for your current OS if you haven't already done so.

This stuff is really one of those instances where an ounce of prevention now will save you a whole heaping pile of e-misery later.

There's a guide on the Bnet website that tells you what you need to do to play with an active firewall. It even helps you with the process of opening ports by providing a step-by-step walkthrough for a few Firewalls.
