I have a 1TB HD on my Dell XPS desktop workstation running windows 7 Ultimate. One day I checked my C:> drive to run clean disk and expected the usual 89GB used, 900GB Free Space.
To my surprise, I saw 979GB used. WHAAAAAAAAT?!?
I did the clean disk and freed up 20GB. Started hunting through the root directories to find the culprit, expecting it to be “Windows” directory. Surprise, it was “Users”.
Drilled down through C:\Users"my name"\AppData\Local\Temp_avast_ and found in this directory a single file, unpDC0F.tmp at 803,557,728KB.
Um…should I delete it. Or does Avast research want me to tie up a week of bandwidth to send it to you for research?
avast places the file(s) that it scans in that location.
When the scanning is done, the file(s) should be deleted.
For a unknown (at this moment) reason, it is not the case on your system.
It is safe to delete the file.
A possible reason why it not gets deleted is that a application you have running is constantly changing the file(s) making avast constantly scanning it.
Interesting. First time this has ever happened for the six years I’ve been using Avast.
I will delete and keep my eye on it.
Thank you for your response.
If it happens again, check the applications/processes that you have running.
I’ve seen a post from a user where it was Outlook causing it.
It was constantly checking for mail (making avast constantly scanning ofcourse) and the (temp) file stayed where it was.
Disabling Outlook solved it.
