I just installed Notepad++ PE 5.2 and when I ran it I got the following positive in TrendMicro. I have submitted it to VirusTotal and it comes back clean. Working on submitting to TrendMicro for consideration as a false positive. Posting here for your information and in case anyone else wants to search before posting, like just did.
