Seems to me YOU are NOT alone !
Have a look at this thread:
What I would do, is post at the Official ESET NOD32 Forum at Wilder's:
I updated my NOD32 just few hours ago, and immediately I received a warning stating that my sens.dll file is infected by win32/patched.g virus.
is there any solution to this?
is it advisable to replace my sens.dll file with the file I could get from http://www.dlldump.com/download-dll-files_new.php/dllfiles/S/sens.dll/5.1.2600.2180/download.html?
oh and, when I hover my mouse over the file in windows explorer, it doesnt show the details (i.e. file version, description etc).
please help, thank you so much.
