I suspect that your original problem with Defender updates may be

 

because you have too many security programs running at once.

 

There may be some sort of conflict happening.

 

Try removing Spyware Doctor, SAS and only run Malwarebytes on demand

 

to see if that helps.

 

It seems that whoever gave you the advice to run the batch file didn't

 

realise you were running Vista. Administrators have different privilege

 

levels in XP and Vista.

 

By running the line:

 

'subinacl /subdirectories %SystemDrive% /grant=administrators=f'

 

you have effectively reduced some of Vista's security.

 

If I understand it correctly that line gives administrators full control

 

of all files on the system drive (C:\) including Windows, System32, Winsxs etc.

 

In Vista only TrustedInstaller should have full control.

 

The standard Vista permissions for system files are:

 

TrustedInstaller: Full Control

 

System: Read and Execute

 

administrators: Read and Execute

 

Users: Read and Execute

 

By giving members of the administrators group full control to system files it

 

is likely that any malware process that manages to run with administrator

 

privileges will now be able to delete, rename or modify etc. Windows system files.

 

I may have got it wrong about subinacl but I don't think so. :-(
