Also if this is the second time you got this message then its quite probable something is re-installing it if you have not done so in-advertantly yourself. Which could indicate rootkit behaviour (especially if your anti-virus is not detecting anything resident as the culprit placing this file, although anything that advanced is usually more cryptographic and random with the file it places)
Whatever anti-virus you are using, you can also install this http://www.malwarebytes.org/mbam.php (the free version - blue button, scroll down a bit) without fear of conflict with your main anti-virus (some do not play nice together). So long as you do not get the paid full version which includes resident protection, although I have this along wit Microsoft Security Essentials and they work very well together.
Anyway, as a second opinion, Malwarebytes anti-malware, once installed, update its signature files, then run a full scan. If it finds something after the scan and asks you to restart, dont do anything else but restart (it writes a temporary tailored startup sequence to get rid of what it finds before the windows kernel gets chance to kick in and mask whatevers hiding).
If you have problems installing malwarebytes, you definately have something nasty onboard preventing it. MBam is like public enemy number one to malware at the moment. A way round that is to grab the malwarebytes installer on another machine, rename the installer as if it was something else .... pigpen.exe for instance, then install it on the target machine (I use a bootable usb for really stubborn cases to get the exe on the machine without booting it from the hd).
All the above may not be necessary in your case, but someone will find it useful. Hope its not as bad as I think, but if your current installed protection has been compromised, it is going to be useless on its own trying to resolve the problem, it needs help.
