Hello Aidan,
Maybe you should try to change Spyware Doctor's executable file (.exe, not shortcut). For example rename it to iexplore.exe or svchost.exe. Also try a random name like test123.exe. Update Spyware Doctor and run a scan. If that won't help, then try to boot your computer in 'safe mode with networking'. Then delete the following directories: (including files in those directories)
C:\Documents and Settings\All Users\Application Data\c9ba (could be any random number in your case)
C:\Documents and Settings\All Users\Application Data\c9ba\WEDDSys
C:\Documents and Settings\All Users\Application Data\WEDDSys
C:\Documents and Settings%UserProfile%\Application Data\Windows Enterprise Defender
NOTE: %UserProfile% stands for your log in user name, usually it is 'Administrator'.
Then if you can, open Registry Editor and remove the following registry values:
HKEY_CLASSES_ROOT\CLSID\{3F2BBC05-40DF-11D2-9455-00104BC936FF}
HKEY_CLASSES_ROOT\WindowsEDefender.DocHostUIHandler
HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Explorer\SearchScopes "URL" => "
http://search-gala.com/?&uid=7&q={searchTerms}"
HKEY_USERS\S-1-5-18\Software\Microsoft\Internet Explorer\SearchScopes "URL"
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform
"[xSP_2:61a6083b6194a2314e3dd54cf9615e36_7]"
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform "876902803"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run "Windows Enterprise Defender"
Next, downlaod Malwarebytes' anti-malware and scan your PC (in safe mode)

WindowsEDefender.exe
energy.exe
ppal.exe
Run a scan with an anti-spyware application again. If the problem persists download HijackThis, run a scan and post the log of the scan.
