Malwarebytes found a trojan and a pup

I decided to go play around with things I knew were unsafe for people who don't really understand them and got a trojan, a pup and some annoying ass chrome extension for it. All I wanted to do is get gimp installed and as they had a torrenting possibility I was intriqued to find out why this would be a thing in the first place so I decided to look into what exactly torrenting is. Long story short I had the correct program and file, but clicked "yes" on some "dude you also want this installed" -thingie which apparently was a really bad idea. I didn't know anything was up until I got a pop-up saying that my browser was not secured. 

After a while of googling "what the ***** do I do" I found malwarebytes and ran a scan with it which to my relief actually found something, a trojan and a pup. Even after quarantining these 2 the original thing - the chrome extension - was still around and for a minute I thought it was gone but it still gets readded to chrome whenever I log in with another chrome account. 

My question is, how do I know that I'm safe and that the trojan didn't give me a keylogger or something within the 5-6 hours it might have sat there. The one thing giving me hope is that when I look at the detected trojan in malwarebytes, it says the directory for the file was (translated) "C:\USERS\myname\Downloads\Unconfirmed" after that it gives some seemingly random numbers and .crdownload at the end. I remember pausing some download that suddenly showed up while I was trying to figure out what I need to do to get rid of the pop-up prompting me to enable a browser (edge I think?) as my default one.

Also I would like to get some help with the pesky chrome extension and sorry for the wall of text.

Please download the attached  fixlist.txt file and save it to the Desktop or location where you ran FRST from.
NOTE. It's important that both files, FRST or FRST64, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real time antivirus or security software before running this script. Once completed make sure you re-enable it.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

 

==============================================================================================================

 

 

Next,

Download AdwCleaner by Malwarebytes onto your Desktop.
 

  • Right-click on AdwCleaner.exe and select Run as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Quarantine button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply
