Tettnang, 8 January 2006 - There are emails with attached malware in circulation, which seem to come from 1&1. So please be careful, if you receive an email with the subject "Invoice from 26.12.2006" (Rechnung vom 26.12.2006). It does not come from 1&1 and the file "Rechnung.pdf.exe" hides a viral code. Avira AntiVir has immediately detected the malware as HEUR/Crypted and the current VDF classifies it as "TR/Dldr.iBill.A".
