Following are some of the files that were installed on my system by a drive-by download;

HDPlugin1015.dll
HDPlugin1018.dll
HDPlugin1019.dll
winadtoolsx.dll
ISTactivex.dll
WUInst.dll

To uninstall these modules from memory, type regsvr32 /u %systemroot%\downlo~1\ followed by the DLL file name, e.g. regsvr32 /u ?%systemroot%\downlo~1\HDPlugin1015.dll?. Remember to add the quote marks. Delete the files after uninstall by typing del followed by the file name e.g. del hdplugin1015.dll or rename it to another extension e.g. ren bridgex.dll bridgex.bak. Doing so will enable you to know how often the spyware came back.
