You have got Brontok or a similar kind deadly trojan on
your pc.
it cannot be removed by antivirus scan.
you can do it by Malwarebytes antimalware. Or Super
Antispyware.
However, since you would use free version of Malwarebytes-
it might not delete the virus. It resides in registry keys.

The simple thing u can do is without wasting time----
Collect all the software installations that you installed
on your pc like -- MS Office, and all programs and Windows
XP Operating system.

Then transfer the C Drive data to D drive.

Now reinstall the operating system.
while reinstallation is going on C Drive, it would ask for
format option----- chose format and format your C Drive
only ntfs as usual. Dont format D or E drive.

Now xp is fresh on c drive, now install AVG freeware
latest version. You can predownload it on blank cd from
cybercafe. Also, install Malwarebytes.

Scan all drives with malwarebytes.
Then copy back your data from D to C drives that u had.
Or if u wish keep it in D drive instead.

you can install Ms-Office and other little programs that u
had like adobe, winzip, revo etc.
