can only access the internet in safe mode

About a week ago everytime I signed onto the internet the page will appear blank with the word "done" on the bottom. I have comcast cable as my internet provider and windows xp as my operating system. The strange thing is when I go into safe mode I can access the internet, also my daughter has a laptop with a wireless connection that goes through my desktop computer and she has no problems getting on the internet. I have tried everything I can think of, I tried reinstalling the comcast software and a screen will appear stating that my network adapter is not bound to a tcp/ip. It shows me how to fix this by going into internet options and then connections and clicking protocol tcp/ip, but when I get to that point protocol tcp/ip is already checked so I don't know why I'm having the problem. I also have mcafee and it keeps telling me I have the very lince trojan but it can't get rid of it. I'm not sure if that is causing the problem but if it's not I'll deal with that one after the internet thing is fixed. Any help will be greatly appreciated.

Try to see if you can do this in safe mode..
Run McAfee Virus scan and see if it can get rid of it.

Be sure to post the name of the trojan file up here so other's can search for it.

If that doesn't work. Start up normal, see if McAfee will tell you the name of the trojan file. Write the name and path down.
Reboot into safe mode. Go to Start/Run. Type 'msconfig' and enter.
In the new window go to Startup tab. Look for the trojan and uncheck the box for it. Reboot to normal and rerun McAfee scan to see if it can get rid of it. Delete the file manually if McAfee can't find it.
If you don't see the file in msconfig, just do a search for the file and delete it.

Don't forget to post the name.

Good Luck.
