I had to save about 1,000 FrameMaker pages today to several PDFs. The process started normally until Acrobat Distiller launched, and then it took about 10 seconds per page to process. It turns out Windows 10 Defender Antivirus has a real-time protection setting that seems to treat Distiller as an untrustworthy app.
I tried adding acrodist.exe as an exclusion to the real-time protection, but it didn't seem to make any difference. When I disabled real-time protection altogether, Distiller worked normally.
Has anyone figured out a solution to this problem yet? Disabling antivirus protection may be a temporary workaround, but it's not practical.
I wonder if this is a temporary escalation of AV defenses in the wake of the on-going SolarWinds attack. Any app that phones home might be considered suspect, until all the facts are in. If any party was an SW client, their apps might be under greater scrutiny even if all they do is auto-update from time to time. Alas, MS itself is an SW client. The trade press reports that the SW software itself was still relying on Flash.
