Just recently when trying to connect using Wanadoo Anytime, the dial up box has ben cleared of my correct user name and the password box is blanked. I had left "remember my password" ticked, so I only had to click connect. Instead of my username there is the name "nix", nothing else. Hence, I have to fill in my details to connect.
Do you think I have a virus and is there a download fix for this please?
Go to control panel then network connections and see how many dial up connections are there. If your original is ther and this new one delete the unwanted one. Check your details on your original by right clicking and properties. (Or as Dio says delete them both and set up a new connection.
If when you reboot the computer or whilst being on the internet for about half an hour this connection returns you have a rogue dialler or virus.
You must sort out anti-virus as a matter of urgency! Delete all your curent antivirus and download one of the free ones. AVG or Avast come recommended. You can only run one antivirus at a time to avoid conflicts. If you have ever had Norton on your system you need to download their removal tool and run that as well. (RNAV2003.exe I think - if it was NAV 2003 or prior. There is another tool for 2004 version.)
