I was just installing PostgreSQL 4.1 with Drupal and other tools. While the Setup was installing phpWiki.exe, Kaspersky blocked the Setup and quarantined two files:
phpWiki.exe, and
StackBuilder.exe
The actual message that Kaspersky report says:
Legal software that can be used by criminals for damaging your computer or personal data. PDM.Worm.P2P.generic.
