I installed Fiddler several months ago (Windows 7) and didn't use it much. I uninstalled it. In the last few days, my Trusteer app has been complaining that some websites I normally visit have a bad certificate.  I have searched all files and the registry on my computer and can't find any residual Fiddler files. I deleted the root and other certificates labeled "DO_NOT_TRUST ..." But, I'm still getting this error (see attached.) Same behavior in IE and Chrome. Something is stuck. Please advise how to remove and restore normal operation.

Hello, Robert--

The most likely explanation is that this isn't related to Fiddler at all, and instead something that you've downloaded installed malware like Browser Safeguard or GeniusBox and that is interfering with your browsing traffic.

You may be able to find the malware using the Add/Remove Programs Control Panel. Alternatively, check your IE proxy settings to find out what port your proxy is set to, then look to see what process is running on that port (e.g. netstat -o) and then find the executable in question and kill it.

Hi Eric

I discovered that indeed, GenuisBox was installed. I try hard to avoid this kind of crap and I don't know how I missed it.

I uninstalled it and Trusteer stopped complaining, so thanks for the tip.
