Autoit infection via Skype?

Hello,

I am turning to your expertise to find a solution to my problem.
On a friend's PC, there is a run script window to open AutoIt files; this window, which has the AutoIt 3 logo, executes automatically at each startup.
Suspecting a malware or virus infection, I run the antivirus "Avira." Some elements are detected, and I delete them; I run a scan again, and everything is clean, but the window still opens.
I go through AdwCleaner, which detects certain registry elements; I do a clean, but it doesn't solve the window problem.
From these two scans, a folder named "skypee" comes up, which contains AutoIt 3 and a source file deleted by Avira.
I run MBAM, but it refuses to execute; the program closes as soon as it opens ("it doesn't run even in minimal startup or safe mode").
Lastly, I run an FRST scan and turn to you for more precision, hoping to find a solution.
Thank you in advance for your help.

Do not use a USB key for now.

Here is the correction to be made with FRST. You can refer to this explanatory note with screenshots.

Open Notepad: Windows key + R,
In the "Run" field, type notepad and OK.
Copy/Paste the following into it:

CreateRestorePoint:
CloseProcesses:
HKU\S-1-5-21-3033668385-1626477122-1689226782-1000\...\Run: [AdopeFlash] => C:\Google\AutoIt3.exe [750320 2012-01-29] (AutoIt Team)

Hosts:
EmptyTemp:
RemoveProxy:
Reboot:


Once the text is pasted in Notepad,
File menu then "Save As",
On the left, go to Desktop,
In the bottom field, enter the file name: fixlist.txt
Click on "Save", it will create fixlist.txt on the Desktop.

Restart FRST and click on the "Fix" button
A restart may be necessary (not mandatory)
A text file will appear, copy/paste the contents here in a new message.

Restart the computer.

thank you for your response and your help
as for the USB key, I put one "my disinfection key with adwcl" which I formatted after the scan and it is no longer opening ??!
after applying the fixlist and restarting, the auto it window no longer appears at startup but mbam still does not launch, which leads me to think that skypee was not the cause
anyway here is the content of the fix log

After several unsuccessful launches of MBAM Chameleon, I did a MBAM clean and a reinstallation for the free version
It works, and after scanning, several vulnerabilities were found and fixed; here is the result in a txt file

Hoping this will put an end to this ordeal
Thank you again for taking your time

Scan your keys with Antivir and make sure it's up to date before =)
