Hello --

My laptop computer had multiple message windows open with "Antivirus software alert" and "Activate your antivirus software" included in them. I was able to get my Norton 360 to run using "Comprehensive Scan" option with selection to shut computer down when complete.

Several hours later when I restarted computer a message "Your computer is being attacked by an Internet Virus. It could be a password-stealing attack, a trojan - dropper or similar." appeared. I ran "Run LiveUpdate" option within Norton 360 and it completed normally. I ran Norton 360 again, this time using "Quick Scan" option with selection to shut computer down when complete.

When I restarted computer, no virus or trojan horse messages appear, but when I open Internet Explorer I get the message "Internet Explorer cannot display the webpage." When I try to "Diagnose Connection Problems" I get a proxy server configuration error.

I don't know what to try next -- suggestions?
Thank you for your help!

Hi,
sounds like you have either part of a trojan left or a version where thy messed up the proxy redirect.

On your internet explorer, click tools>internet options
(if you can not do this, mouse right on a desktop icon of IE and select internet options or do start>run, type Inetcpl.cpl and hit return)

on the window that appears click the connections tab

about 2/3rds of the way down on the right is the button "LAN Settings", click on this

on the window that appears, in the bottom half make sure "Use a Proxy Server for your...." button is not checked, if it is, uncheck it and click ok
click ok on the internet options window
try and use the internet

This will get you access to the internet but it does not remove the trojan. It may have been killed by your AV but running something else (I would uses Mbam but you may want to wait for one of the staff members to respond) would be a good idea

Also some versions of this virus will reset the proxy as soon as you exit internet options so if it reverts to not letting you then let us know
