No i don't think i have and/or i'm using 'Winapp2.ini' ..though the file name does look familar, it might have been called 'Winapp1.ini' ..or something like that. What is it, what does it do ? ( pls. explain in simple form )
...as for the link 'http://forum.piriform.com/index.php?showtopic=34509' ..seems like i'm not the only one.
Microsoft Security Client ("MS Security Client") is also a part of Microsoft Security Essentials.
You need to untick both of these so that Microsoft Security Essentials is not cleaned by CCleaner anymore:
* MS AntiMalware
* MS Security Client
Piriform need to have it turned off by default, change the naming of it, and put in a warning section so people know it's going to mess with Microsoft Security Essentials because people have been posting about it causing problems for too long now.
