    So… that was a very informative post Mr. Bloom. Thank you. But now I’m in a bit of a quandary since you’ve given me so much information. And I’m not sure what to do.

    I’ve always been suspicious of ClickToRun.exe, and it routinely gets flagged by my security software (Bit Defender) so I go through phases of letting it phone home or blocking it’s attempts to call out to somewhere on the web. My computer never shows the signs of infection that you mention in the post.

    So I guess my question is: How do I determine if the ClickToRun.exe on my computer is the legitimate file from Microsoft or a piece of malware placed there by criminals???

    Thank you for your time and attention.
