This morning a product I have been using for a long time - "1st Javascript Editor" by Yaldex came up as being infected with a Packed.Win32.Black.d virus and was quarantined as having a high risk. I went to and downloaded the (newest version) and scanned it and it was also immediately quarantined.
I believe this is a false positive but would welcome any feedback.

Operating System:Windows XP Pro
