I'll stick with the two programs, for now. Not a big fan on online
scanners, for the reasons you mention.
Sorry to confuse with asking about two different programs. Both the
SAScore.exe and the a2service.exe run as Services and both can be set to
Automatic, Manual or Disabled. I have both set to Manual.
Using SysInternal's AutoRun, I see the hook you're talking about:
Description: SABShellExecuteHook ClassShellExecuteHook
Publisher: SuperAdBlocker.com
Image Path: superantispyware\sasseh.dll
What does that do, exactly?
And you are correct about using the content menu entry to scan a file
with Emsisoft Anti-Malware. (They don't call it a2 anymore). Once the
scan is complete, the a2Service is turned back on. When it is set to
Manual. I stopped it and set it to Disabled and Emsisoft Anti-Malware
will not run.
SAScore does not exhibit that behavior using the content menu entry to
scan a file with SASfree.
Now I know how to deal with the two services. What about the SAS hook?
Just leave it alone?
