Symptoms: red cross icon in windows explorer next to c: drive. Also, Rundll dialog box pops up on starting windows, saying specified module fddrcrny.dll file could not be found - looks like spam, I have completed all the steps in techspot.com vb topic58138 and have attached the HJT logfile, combofix log files. AVG Spyware freeversion did not allow saving report but it did find malware - which was quarantined and deleted. Panda Antiroot did not find any root problems. Many thanks for taking a look at this,
