As of yesterday, my C:\Users\Jay\AppData\Local\Temp_avast_\unpBE97.tmp file started growing uncontrollably. It consumed 100% of the available disk space. Regardless of what files I deleted to free up space to even shutdown what I was working on, it continued to consume that space–very quickly. I had to forceably shutdown Windows.
Coming up in Repair Command Prompt I was able to do analysis to find this file as being the visible issue. At present it is 42,274,095,104 in size.
Oddly enough, a friend of mine had almost an exact same issue last Wednesday, 12-4-2013, where an Avast .tmp file consumed 170GB! (same symptoms, same directory, different file name). He deleted the file, shutdown Avast, uninstalled Avast, and the visible symptom didn’t return.
I haven’t yet deleted the file. Should this be reported to Avast? Does Avast need to see the contents of the file or anything else to determine if this is a new type of virus/worm that makes Avast look bad and Avast isn’t able to detect the issue?
HELP, I’ve got to get my system back clean!
