HELP, Malwarebytes found trojan

[Sipty21]

Hi everyone,

a couple of days ago I downloaded an .exe for a game, I was sceptical of it its safety, so I tested it with virus total (it said it was clean) and then tested it again with malwarbytes after downloading it (nothing was found at the time). Afterward, I executed it. It didn't seem to do anything though, which made me worry a bit, therefor I ran malwarbytes and windows defender again and this time it found something which was quarantined. I don't remember what it was called exactly, only that it was stored somewhere starting with HKS.... or something along those lines. After the quarantine, I ran a couple extra scans and nothing was found, so I thought I was good.

Yesterday, out of the blue, while I was in discord, my account sent messages to all my contacts with a steamgiftcard hyperlink. I reset my password and did a windows defender and malwarebytes scan again and this time malwarebytes found two trojans:

• trojan.fakesig
• trojan.pyengyloader

They both got quarantined and afterwards I did a couple more scans, even a windows defender thorough scan plus a windows defender offline scan (both came up clean). Before calling it a day I checked the taksmanager autostart programms and found a suspicious .exe:

I deactivated its auto start function but if I try to find its location on my c-drive it doesn't show up, I also can't examine its properties.

I would really appreciate some help from someone that understands what's going on. I am unsure if my system is still at risk.

Extra Info: Malwarebytes also always flags my downloaded cheatengine which I use for mods in Elden Ring for quite a while now. As far as I am aware, that one is safe though and just gets flagged because of what it can be used for in general.

Some help would be really appreciated!!

My computer seems to be running fine. I didn't notice any more strange behavior. The weird .exe shown in my initial screenshot seems to be gone as well.

Thanks for the info about the programs to update/uninstall. I updated all of them.

I also had two small windows updates done, so I am on the latest version now.

 

Looks like everything is fine now.

A massive thanks for the fast responses and the very easy to follow instructions!!
