I just looked AutoIt error up and it seems to be a Worm virus.
Download, install, and run Malwarebytes: https://www.malwarebytes.com/premium/
Note that you will be installing a free trial of Malwarebytes commercial product that offers real-time protection against malware. You can uninstall it after you do one scan. If you choose not to uninstall it after your initial scan, it will work as advertised for 14 days.
In addition to running Malwarebytes, I suggest that you also run free ESET on-line virus scan: Free Virus Scan | Online Virus Scan from ESET | ESET
See what these find and report what results you get.
