Technical Description:

Win32.Worm.P2P.Puce.B is virus which spreads itself by infecting RAR and ZIP archives found on computer in predefined folders.

When first executed, it copies itself into %Temp%\svchost.exe and adds a key into the registry to auto-start itself : HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\WindowsServicesStartup = %Temp%\svchost.exe  1

This malware will then start searching for RAR and ZIP archives inside some predefined folders, on local C,D and E drives:
