Pintae is an Internet worm that spreads by e-mail through messages with infected attachments. Once the user opens such an attachment, the parasite secretly installs itself to the system and runs a spreading routine. It sends bogus e-mails to addresses in the Windows Address Book. The worm also copies itself to unprotected network shares. Then it runs a payload. Pintae changes some system settings and disables the Task Manager as well as the Registry Editor. It also terminates popular running antiviruses, firewalls, anti-spyware programs, trojan removers, registry and system utilities and other security-related processes. Pintae automatically runs on every Windows startup.
