AMozilla folders in my AppData/Roaming profiles - legit or malware?

There is a folder called 'Amozilla' containing a folder called 'AFirefox' under Users/_____/AppData/Roaming, in addition to the regular Mozilla folder. The Amozilla files are all from 2018 - no recent use. Are these legitimate? Safe to delete?

The regular Mozilla folder contains two Firefox profile folders: one with recent files, the other all from 2018. Safe to delete the defunct profile folder? (I am the only user of this computer.)

Thanks.

Entries claim Malware.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Is there also a aMozila or aFirefox folder in the secondary location in AppData\Local ?

You can remove this folder as it isn't used by Firefox.

Thanks for your replies.

There is an AMozilla folder in AppData\Local too. I hadn't looked there at first. Only saw it in Roaming.

I will remove both, I guess, but was this ever a legitimate folder?

FredMcD, yes I saw some of those forum conversations, but nothing from Mozilla itself addressing the 'AMozilla' phenom specifically.

I haven't noticed any particular performance issues in the last year.

Hi. Just noticed this post - so probably too late to the party to be of help.

Re the "Amozilla" folders, this is the sort of thing that might have been done by a support admin whilst fixing an issue. I.e. create a new profile and then rename the old with a leading "A" so it's still there but inactive. I've seen that done by professional IT support a few times - even done similar myself occassionally. Of course, you never "get back" to cleaning the old, now redundant, folder/file up... Or it might be malware just possibly - unlikely if nothing picked it up and your system ran ok.

Either way, deleting it was fine.
