Then at least portion of the virus scheme most definitely got onto your computer. From what ive gathered here Its supposedly written to trigger on certain date, download the lumma stealer, take what it came for and delete itself, I cant say anything about whether or not did the malicious actor receive the data this scheme was after.. and you have cleaning, then password changing ahead of you just to be safe. In that order.
What ive heard from here its designed to download malicious material, if user has activated the infected exe file, on certain day. In this case it was apparently 20th of august. Note that as long as your computer is infected, changing passwords dont necessarily help at all since virus might just keep just sending them to whoever is behind this. You need to clean the virus off, then change your passwords and restore whatever changes it has tried to make, like exceptions in windows defender or other antiviruses, so it can operate free.. out of interest check windows defenders list of folders set as exceptions if the virus set its own folder as exception from scans.
I cant really tell what advices in regards to cleaning effective since my case was different. I didnt have a folder and files wasnt there despite definitely running the file. Even still there is one at least one user who received notification that their instagram account was being fiddled (whether or not it was unrelated activity.. who knows). I still went through my entire system with whole circus of tools, changed passwords and raked through defender and antivirus for exceptions..
