I am a NIS user since 2003 and upgraded from 2011 to 2012. My system was infected with two infections (1) Worm: “Win32/Autorun!inf” in C:\System Volume Information\_restore{….} folder and (2) an Adware: “Win32\OpenCandy” in C:\Documents and Settings\User\Application Data\openCandy\OpenCandy_A64….\DLMgr_3_1.6.87.exe. NIS 2012 did not detect these. Sluggish and frequent disconnection of internet forced me to use another software which at the end detected. But, I , still suspect some infection in my system. Can Symantec or the community offer solution to get rid off any infection in my system. With thanks, Desikan Srinivasan.
