Title: AVAST VULNERABILITY- CAN BE BYPASSED AND REMOVED!
Post by: kubasinski13 on October 30, 2021, 01:01:13 PM

Hi, i've just found a virus which destroyed my operating system.

After running this virus, program activates payload (in command line)- downloads trojans and starts bypassing avast protection. System crashes and restarts- after restart i can't run avast (UI Error or something else- i don't know what exactly, avast services in task manager are showing properly, but antivirus don't work).

I'm sending virus to analysis. Please improve your self-defence in your AV, because i was disapointed of that. I was wondering if you can add proactive defense to stop running suspicions files with extansions: vbs, hta, cmd, bat, ps1, ps into your antivirus engine.
