I am seeing a file named wanancsp.dat located at:

This is on a Lenovo Thinkpad X201T running Windows 7 Ultimate x64.

    I ran Windows Defender and nothing on the machine registered as malware or spyware. How can I find out if a legitimate program might be using this file?

    According to the anti-malware sites online, that process isn't legit. Use whatever program you have to remove it..

    Can you recommend to me your favorite malware removal software? Windows Defender, which is what I am using, obviously isn't doing its job.

    I did a quich search on the web, and couldn't find any site relating this file to malware. Have you tried to see the contents with an editor ? Have you tried to rename it ? Did you update malwarebytes before running the scan ? Maybe it is not malware after all.

    Yes, MalwareBytes was just updated. I opened the file with Notepad++ and this is what I found. It's just a lot of this--about 5000 lines of gibberish. èMx œàIð3nÃeˆvÈ.•Oy^R$Kô[êœÃ®N) ¤9ZI?×Üæ‰xšwÁŽó A§üÁC+˜DXƒòÙÔŸ#~%¦ÌícV@êJ®E2lÇó-cô¤ö–”’­”eŸûŠ³õسïOÝ~Ê4@&¸+ei¹ôã¡ZŽ¸KxH4§Ô¥&¹ rMÜ…þ•Š•¸Lݼ~åw•ˆßÏÖ©ÅÑlt#[u<”i´ ©w¦{b¾s“²Àú…CÞþ°3 õv²mq

    I would recommend for you to remove that file if you are able to. You can also try using Trojan Removal tool. If still doesnt recognize, then i dont think theirs a harm in deleting the file, especially if its sitting in all users sharing Documents and with those weird coding like that???I definately would remove it. Not 1 Windows Vista or 7 I have come across with such file in that location, unless the users itself put it their for a reason.

    I used MWAV, but it's still not coming up with anything. The computer is absolutely clean. Might it be related to LastPass as an encrypted datafile for the passwords that I store locally?
