"Note also that at least twice already, avast! team has averted a meltdown (disaster) by using this tool". ABSOLUTELY! Two-thumbs up on this!!
"I think people may be getting a little hot under the collar...."
I started this post (two pages ago) with two simple, direct questions --- which have yet to be answered:
1) Can someone enlighten us as to the nature (reason) for this emergency update? What did it address/fix?
2) Why is this fix running every time I reboot, rather than just doing the job once?
Had we gotten an equally direct response from someone "in the know" (like Vlk), there may have been no need for subsequent debates/rants.
If, for security reasons, avast can't publicize the specific "nature"/reason for this update, a simple statement to that effect would suffice.
But we still need/deserve an answer to the question: Should we continue to let this update run, again and again, on all system startups? Or should we remove its startup entry, after it has run (at least once)?
And if it's supposed to run every boot: then for those who accidentally or intentionally removed it, will the "Emergency Update" TASK, in Task Scheduler, reinstate this startup?
Direct answers to these simple questions should take care of everyone's concerns.
