Guys, if you ever needed a reason not to use Facebook, then a wild fire spreading Malware trojan email would be one of them.
Basically, it was the old faithful Malware trojan, where it would report that you had a virus on your computer and then direct you to a web page where you could download a virus checker. I couldn't believe it when I found out that it had been sent around inside Facebook. I hate the site myself but my wife uses it.
Anyway, basically, the only way to get rid of this virus if you come across it is to download the latest Lavasoft product (Adaware FREE Download, www.download.com will have it). Install it, restart your computer/laptop in safe mode, run the scan, clear the virus & reboot.
This will clear the virus, but you may find that your internet browser wont work even if you can connect to Messenger. The reason for this is that the trojan will activate your internet connection Lan settings and tick the proxy settings. To finally fix this problem, go into the internet settings options, go to the connection tab, into LAN Settings and untick the proxy settings. Restart and there you go. All fixed and back to normal.
Hope this helps someone.
