Deleted files due to virus, now internet won't work!

[Zapcat]

I got a dialer trojan virus (Bho.A) on my laptop. My
anti virus couldn't delete the files so I deleted them.
BIG MISTAKE! Now I can dial on to my isp but I cannot
access the internet. IE cannot access any sites & my
anti virus won't update.

How do I fix this? I'm on XP Pro.

Thanks!

Try reinstalling Internet Explorer, and you may also want
to try running SFC /scannow fom a command prompt.

First I would check your Hosts file. To check your hosts
file, do the following (Windows XP):

1. Click Start, and then click Search.
2. Click All files and folders.
3. In the "All or part of the file name" box, type: hosts
4. Verify that "Look in" is set to "Local Hard Drives" or
(C.
5. Click "More advanced options."
6. Check "Search system folders."
7. Check "Search subfolders."
8. Click Search.
9. Click Find Now or Search Now.
10. For each one that you find, note its location. (This
is displayed in the "In Folder" column.)
11. Right-click each file, and then click "Open With."
12. Deselect the "Always use this program to open this
program" check box.
13. Scroll through the list of programs and double-click
Notepad.
14. When the file opens, delete all the entries in the
Hosts file except for the following line:

127.0.0.1 localhost

15. Close Notepad and save your changes when prompted.
