Hello Dineke (@gebruiker1),
Thank you for working with us through our helpdesk to diagnose this issue. I already updated you on your ticket that the problem has been resolved. But since this is a public forum, and for benefit of community members seeing this, I think it is important that we provide a proper update to this thread. More so because mere mention of spyware or malware is enough to attract attention.
As we had initially assured, the extension files themselves are totally safe. It was a false alarm due to a DNS setting. It was reported to McAfee and they have removed the warning. You should be able to download and update the files without any problems now. If you have any questions feel free to post them here or on your ticket.
I also have a request from ProfileGrid team – since the issue didn’t turned out to be what it initially appeared, and has been duly resolved – please consider modifying your review. ProfileGrid is a being actively developed by small team of passionate people. We take every feedback seriously, and this really bought down the morale. While we try our best to make every ProfileGrid user happy, few things are time bound due to external dependencies. Still, if you feel we missed anything, do write back to us. As I said, we want to do all we can to make you feel happy.
Thanks again for working with us to get this resolved.
