I don't know. That's all i could get from them. I can't risk trying to install again to see if it would happen again. VERY STRANGE!!!!!

According to Sentinel One, there was actually malicious code in it that tried to do damage. This is from the follow-up email I.T. sent me that includes Sentinel One logs:

"Now that we have the logs from Sentinel we know that the library program used Fredo to deposit a payload through SketchUp onto your computer. That part is not abnormal - that is exactly how most programs are able to install themselves. Once the library passed the file through to your computer, the program ran itself and we now know that the file was a multifacited attack that was a combination of ransomware, credential scraping, and an trigger mechanism that was designed to evade detection. Part of the log file is below showing what Sentinel One was seeing.

EDIT: I was trying to upgrade both LibFredo6 and FredoSketch at the time so not sure which one I was updating for sure. I believe 85%/15% that it was LibFredo6.

I am a long-time fan and user of all of Fredo's tools. Unfortunately, I was upgrading LibFredo to latest version on Thursday and it caused Sentinel One on my work computer to quarantine Sketchup rendering it useless until our I.T. department could reinstall. However, they would not allow reinstall of LibFredo or FredoSketch which were the 2 things I was updating at the time. Without LibFredo, the other Fredo Tools that I have, including ones with paid license, are useless with out LibFredo. Our I.T. vendor told our liaison that "Based on extended looks at those, they more than likely have malicious code in them that we are not willing to risk introducing onto your computer and/or the ****** network".

Has anyone else ever had any issues similar to this? Obviously, Fredo Tools are a great addition to Sketchup that I can survive without but would rather not.
