how to get rid of this message at start up

[Guest]

I was trying to delete viruses manually and now when I boot up, I get this
message
"c:\windows\nail.exe - unable to find c:\windows.exe. Make sure you type the
name correctly, and then try again. To search.....etc"
Well, a search for the files/folders etc, find nothing. In my msconfig, I
have the following check:-msmappau, ccApp, timesquare, ctfmon, msmsgs,
DSLMON(which is the modem).
While I was trying to delete whAgent, one of the files, webhdll.dll cannot
be deleted, so I remain as oldwebhdll.dll. Is this the possible cause for the
message.
I dont think Nail.exe is up to any good, please advice, thanks

The above should answer all your questions on the issue, as well as how to
resolve it.

Many viruses and malware will break/disable antivirus software. This can
particularly happen if you had an old version av (before 2004) and/or
had let your virus definitions subscription lapse. Scan with either
Sysclean or Dave Lipman's Multi-AV:

Continue with general malware removal - There is a section on removing
Nail.exe, too:

Depending on how badly the computer is infested, you may need to run
HijackThis and post your log on one of the specialty forums (not here,
please). There is a list of HJT forums at my site, too. When all is
done, make sure you have a full-featured, current version antivirus
installed with an active subscription and the latest virus definitions.
Do a thorough scan with it in Safe Mode.
