MSI SecureDoc--File encrypter--Handy for encrypting any kind of file into your HD. It has a password to keep others from decrypting the files.

All that I know is that once AVG removed this from my computer the computer reboot itself and was never able to come back up again I will let you know if I find out more when I repair this

logon.exe by Leisure Ltd is an adware that uses explorer.exe to pop up ads in chinese. The ad's looks similar to the msn messenger generated alerts. Ads will be triggered when browse to some sites. For me, www.youtube.com will trigger the ad pop-up

When logging as an administrator on XP the PC restarts over and over again!

I picked up logon.exe two nights ago and cannot get rid of it.

It turns my computer off and I have to start and restart by using the safe mode with networking tab to keep my comp. on!
  paula  
this is causing my comp to show an error at startup and will allow about 5-10 minutes of usage before an auto shutdown and restart. This is a continual cycle as long as I let it go. I can't do a system restore to any point either. Any recommendations?
  toni  
Had AVG suspect it of infection through a trogan, so moved to vault, restarted computer came up with an error when logged on but still logged on fine for me, have noticed no problems so far
  Simon  
My info on logon.exe: upon windows startup AVG "detected a threat" which was logon.exe. I clicked on heal, nothing happened. When I opened my computer again, i got an error message telling me windows cannot locate and start the program logon.exe. So now it will be giving me this annoying message upon start? The pc seems to be working fine tho

AVG removed it and now Windows will not load

This process indicates that your system has been infected with a very bad keylogging trojan. The worst thing about it is that it actually encrypts the files in the user's "My Documents" folder in XP, and when it is removed those files are no longer accessible and are totally lost -- even though they're still technically there, once you clean out the virus (which decrypts the files making it appear as if the only thing wrong is that your computer has slowed down) there is no way on earth to retrieve them. The best alternative at this point is a destructive reinstallation of Windows.

msgbox started to come up after a virus was detected and cleaned then it started saying no logon.exe file found

I had 3 worm allerts 2 nights ago which proceeded to crash my computer. The internet connection was completely buggered. A scan got the worms out and internet connection re-established. Now a notice - Cannot find logon.exe. Also notice of Kernel verifier problem. There seems to be no further problems though.

I think Logon.exe is a Microsoft file, but it would be best to ask Microsoft support. I too have lost it somehow, but I will ask Microsoft about it.
  Derek Jacobson  
the generic logon.exe is included with windows xp and other versions, if it is not modified or a modified version, this is the program that displays the computer's logon prompt ie: your name and logon picture before windows is completely started

Antivirus notices it right away on login. It is being created in this Vista system to folder c:\program files\Windows\logon.exe . Everytime it is quarantined or deleted, it is being created again. Thousands of times an hour then. Haven't noticed that the machine would be slower or anything other significant, just the fact that it keeps being created and antivirus doesn't like it.. I don't use internet on that machine though...

Logon.exe was in "c:\program files\windows\" and caused the antivirus software to go berserk. However when cleaned in safe mode the virus was been able to removed and after that no problems with the system. Not needed if in this location.

System restore worked for me! It started two days ago when I accidently accepted the internet access of 'Window NT-aanmelding' (Dutch word). The next day I had the problem that the system was shut down after 5-10 minutes. I did the system restore and restored to the settings of two weeks ago and now it works again!
