That means, that all your exe files are infected with a virus. So Backup all your Data, format the Harddisk and install Windows again.
Bevor going online the first time, you have to install the newest Servicepack avaible for your Windows Version.
You have to download it from a other clean PC, otherwise the downloaded servicepack will become infected too.
Using the offered cleaning tool for “your” virus is not a good choice IMHO, because it is not able to clean the files 100% and the chance, that the cleaner destroys the file is high!
DavidR: the D variant is a piece of ZOO virus… it was never so widespread as the other three variants… we got only a few samples of it… the D variant is detected, but not covered by cleaner… and the cleaner code is called for Win32:Parite, when the user pushes the “Repair” button afaik… Igor could confirm it…
