Can you get a connection when you boot up into Safe Mode with Networking ?
How did Telus determine you are infected with the Citadel virus ?
If you can connect to the Internet in Safe Mode with Networking then download NPE after reading through the page
https://security.symantec.com/nbrt/npe.aspx but see if using the restore points back to before this problem occurred while in Safe Mode will resolve.
As a belt & braces after running NPE also run ESET Free Online Scanner
http://www.eset.co.uk/Antivirus-Utilities/Online-ScannerClick on Advanced and check all of the boxes except the last one (for a Proxy I think) then disable your AV program immediately before hitting the Scan button.
This scan will take a little while to complete.
If you aren't able to connect while in Safe Mode etc. and the restore points don't resolve, then see if MSRT can do anything for you.
Go Start - type mrt.exe - press enter and opt for the full scan - this can take a few hours to complete.
The Citadel virus can lead to Ransomware but as you don't have an Internet connection to pay any ransom, then you won't have that.
If these suggestions get you back up and running and virus free, then I strongly advise you to create a system image onto external media.
