When first run W32/Rbot-FWY copies itself to <System>\2x32.exe and creates the file \a.bat.
The file a.bat is detected as Troj/Batten-A.
The following registry entries are created to run 2x32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Numerical Xterm Agents
2x32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Numerical Xterm Agents
2x32.exe
W32/Rbot-FWY sets the following registry entries, disabling the automatic
startup of other software:
HKLM\SYSTEM\CurrentControlSet\Services\wuauserv

HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess
Start

Note: disabling autostart for the SharedAccess service deactivates the
Microsoft
Internet Connection Firewall (ICF).
