install.exe found on external drive - how do I find out what it is?

Can anyone help?

My computer was accessed via remote access scammer 2 nights ago and although my computer has been checked any appears to be safe - (microsoft checked) - my partner has a computer on the same home network and her computer now has (2) 'install.exe' files that have appeared on her external hard drive within folders with names such as 080eb699a612b22018 and f9e359c6c3f913d19353. An additional folder appeared last night They seem to have appeared at about the same time that my computer was remote accessed via the escammer. The files won't allow to be deleted as message saying they can only be deleted with admin access although my partner is the only user and has admin access. Have run Malwarebytes, spybot but files remain. Computer now has Microsoft essential with firewall.

Two questions.

1. How do we know what the install.exe is and if it is malcious hacking or simply system file?
2. How do we remove it if it is malicious?

Hi,

These files should be considered malicious - do not attempt to run them.

Please follow the instructions here:

Windows Defender Offline

Would a system restore be advisable to a previous date?

also.. is it advisable to try to change permissions to try to delete them? AND is it like that these install.exe files already placed spyware etc on the computer?

Hi,

These files reside on the external drive correct? I would let Windows Defender Offline do its scan before attempting anything else.

A System Restore would only be good if the system was infected - lets see if that is the case using Windows Defender Offline.

The offline version boots and runs from a DVD without requiring a boot into Windows - this way it is immune from any smart malware that that tries to inhibit scanning from within the Windows environment.

final question.. does the defender HAVE to be saved to a CD/USB or can it be run from being installed on the computer itself?
