I use Avast antivirus, and I just got a notification saying that it blocked something running through PowerShell.exe. I'm worried about what this means and what steps I should take next. Can anyone help?

Happened to me before! The first thing to do is isolate your device. Disconnect from the network to prevent any possible connections to a malicious server. Once isolated, go through the antivirus logs to identify what was trying to run. If you're not tech-savvy, donโ€™t hesitate to ask for help from someone who is! A clean scan is also a good idea.

Sorry to hear you're having issues! Typically, if something gets flagged, it's wise to disconnect from the internet to prevent any potential malware from continuing its activity. After that, you might want to perform a thorough virus scan and check for any unknown users or profiles on your computer.

It can be frustrating when your software gets flagged. First, check your antivirus logs to see what was blocked and if it gives details about the script. Itโ€™s essential to understand what triggered that alert. If necessary, you can look for any suspicious files that could be related to PowerShell by searching for *.ps1 files on your drive.
