I noticed you had TDS3 installed at one time.
If you still have it do a full system scan.
If not, remove at least these files and folders:
C:\Program Files\ISTsvc <= entire folder
C:\WINDOWS\sbhyan.exe
C:\WINDOWS\system32\o3v5iqbe.exe
c:\program files\180search assistant <= entire folder
C:\WINDOWS\dancf.exe
C:\WINDOWS\system32\elitejpd32.exe
