Since then this same virus is being detected on a regular basis and at the time of posting, I received it twice in 5 minutes.
Then, apparently, you have not removed the cause of the contamination.
I generally move it to the chest, is this completely safe and is there any way it can spread?
Anything sent to the virus is isolated from your system and can cause no harm.
You can safely delete those files. Highlight the file or files you wish to delete. Right click and select delete. Done!
Finally, is there anything I can do to prevent it downloading to my computer?
Yes, but it depends on what you have already installed. If you have Avast properly configured, then the virus should have been detected.
An email filter such as K-9 or Mailwasher can also prevent such "trash" from reaching your computer.
The message subject tends to start with "Greetings" so I thought filtering out anything with that in the subject might catch some of them.
How are you filtering out "Greetings"? This should have done the trick. What program are you using to filter?
