A fairly common issue after removing a virus from your PC is that the internet no longer works.
This is usually due to settings or corruptions in either your "hosts" file or "Winsock" aka "LSP" that the virus/malware caused when it installed itself on your PC.
Thankfully correcting this issue is simple.
Step 1: In Windows XP search for "hosts" in Vista and above type "hosts" in the windows search bar.
When you locate the "hosts" file open it using "Notepad".
At the bottom of the text file you should see only 127.0.0.1 localhost
If there are more entries, delete them and then save the "hosts" file.
Step 2: In Windows XP Service Pack 2 goto "run" then type "cmd". Windows Vista or higher just type "cmd" on the Windows search bar.
NOTE: Vista/Win 7 users may have to open "as administrator" to continue.
From the black screen (command line screen) type in : netsh winsock reset
Then restart the computer,
Lastly, download CCleaner to clean temporary internet files etc...
I recommend you view my tutorial on this subject. It also has screenshots of the steps I outlined above.
If the problem re-occurs after these repairs it is possible a virus / malware is still present on your PC.
Best Wishes-
