I had the same problem as others are having with:
media9s.com/cgi/crhwmrxg.php?gggg=6733616xxx
nopagency.com/cgi/kpudd.php?ddddd=6733616xxx
88.80.7.152/cgi/oejo.php?dsi=6733616xxx (no xs on the ends)
for about a week, I tried everything I had, full scans with Avast, Malwarebytes & SuperAntiSpyware and they did not find these. I turned off restore, dumped my temps. did a reboot, turned System Restore back on, updated Malwarebytes (always do this) and did a full scan (said clean), updated SuperAntiSpyware and it found these: (trojan.Dropper/Win-NVxxx(without the xs))
in that there were 2 -
(C:\WINDOWS\MSVIDEO.DLLxxx(without the xs))
I moved them to Quarantine yesterday and have not seen the blocked warning again ! I hope I'm done with them...I hope this helps someone...dave
