Okay, now we are getting somewhere. ISpyNow uses files it places under Documents & Settings, in various folders. And it rewrites them if they are damaged.
Start hijackthis, select Scan Only, place checkmarks against all the entries listed below that still exist, and then press Fix Checked.
O4 - HKCU\..\Run: [nah_Shell] C:\Documents and Settings\c\nah_jpde.exe
O4 - HKCU\..\Run: [HPseti] "C:\Documents and Settings\c\Application Data\Google\runhh6110411.exe"
Delete:
C:\Documents and Settings\c\nah_jpde.exe
C:\Documents and Settings\c\Application Data\Google\runhh6110411.exe
Then search D & S for files with these names , they will have similar file modification times:
learn32.dll
rehh
vigrs
Ina
comm3
fsh1
mscscc.dll
run611041
..and delete them also. Restart, and see if they have stayed deleted. Post back with a list of files that you found and deleted, please. You might order the files in each folder by Modification Time, and note any other files with the same time.
