AVAST is used by some people as a security and virus protection solution on Windows. However, such supposed security products often bring weaknesses to your system. German blog reader Nobody already pointed this out in this comment at the end of last week (thank you).
Project Zero exposes vulnerability
The vulnerability report they mention wasn’t just me, it was a Project Zero collaboration with @natashenka
I think this is the right decision, it was a *lot* of attack surface. https://t.co/iFyry17HD0

So in principle AVAST has built in something like a predetermined ‘weak point’ that only needs to be attacked. So it was only a matter of time before an exploit would show up. So the antivirus vendor reports in the above tweet that it had been aware of the issue since March 4, 2020. After Ormandy published his GitHub post with a tool to analyze the emulator on March 9, 2020, they decide to disabled the emulato, to protect hundreds of millions of users. According to AVAST, this does not affect the functionality of the antivirus solution.
