Windows 7: Avast Antivirus holding my files hostage

Avast Antivirus holding my files hostage

Avast Antivirus holding my files hostage-avast_antivirus_file_in_use.png
Recorded some gameplay video today. Tried to rename it, move it, delete it while I was working with it but Windows says, NOPE, Avast Antivirus is still using it!

Now what the heck would Avast want with an *.avi file, especially since:
  • It's a file I created (i.e. not downloaded off of or ripped from the Internet)
  • It's too big to fit in my virus chest (4 GB file, chest size is 32 MB)
  • I regularly do this as a hobby

Last couple of weeks ago, I had a ~36 GB AVI file, I tried to delete it and Windows wouldn't let me because Avast wouldn't leave that alone. I had to stop the Avast! Antivirus service to do anything with files. More or less, exclude the directory where I store all of my raw encodes.

Disable avast. Right click the avast icon and choose disable for 10 minutes. Once disabled, are you able to delete/modify the file?

It could be that avast was running a quick scan when you went to open it and that caused the file to be locked. Was a scan running in the background?

There were no scans being run, other than File System Shield, which had been set to scan all files, which is a pain because every time I go in and open a large 7z-compressed archive, it takes upwards to 3 minutes to open. "Test whole files" (in the Sensitivity settings) is turned off.

I'm not sure which "scan all files" setting to use, whether to scan files when opening or to scan files when they're being created or modified?

So with avast disabled, the problem goes away? Just want to make sure, if so we can dive into avasts settings and see whats up.

Norton has a setting to scan any file when opened, does Avast have that? if so disable it.

Does Free Avast Antivirus Have A Firewall?
I'm just about to change from paid Avira Pro to free Avast antivirus. The Avira had a firewall, but does the free Avast have one? If not, what should I do? Am I right in thinking that my Win7 has a firewall, and if yes, is it enough to rely on this? Thanks for any advice.

Avast antivirus
I recently ran a scan with my Avast anti virus program. Several Threats found came up in the results. There we're options to delete or isolate them. I tried both but nothing happened. How do I get rid of these viruses for good? Thanks. Hal. __________________
