However, from what I can determine, it is a Logon Stub for the Thinkvantage Fingerprint Software. I've scanned this .dll at virustotal.com and jotti.com, and they say it's clean. I've researched online and I've examined the file properties. I am preparing to file a false positive report with Malwarebytes, but I need to clarify something about the Malwarebytes software first. My software has the following properties, and I would appreciate it if someone else who has this file if they could check theirs as well. Size: 87.5 k, Size on disk 88 k. Created March 14/07, modified March 14/07. Version 188.8.131.5224. Logon Stub. Copyright (C) 2001 - 2007 UPEK Inc. Internal name PSQLPWD. Long list of language versions. Legal: Touchchip. Original file name: psqlpwd.dll. Product name: ThinkVantage Fingerprint Software. Version 5.6.1. special build description win.x86-rel.tfs2. This is installed on a Lenovo R61 Thinkpad. I'm not using the fingerprint software at this time, but I wouldn't mind the option being available in case I change my mind. Thanks! Hope to hear from someone soon.
