ESET, both home version 12.x and Bussiness version 6 and 7, have started to block downloading new LLR jobs as of yesterday night.
In my case, AP27 is not affected.
Adding boinc.exe and boincmgr.exe among Excluded app in Web/Mail filters should help.
Since PG has not changes it's LLR apps recently, something has changes on ESET side I assume.
I'll investigate further in couple of hours...
EDIT: I found that web filter blocked this URL
for application boinc.exe considering it phishing page.
I have reported this as false alarm.
Badge score: 1*1 + 5*1 + 7*1 + 8*8 + 9*7 + 11*1 + 12*3 = 187
