Windows 10: Avast disables JavaScript engine in its antivirus following major bug

Brink · Mar 11, 2020

Czech antivirus maker Avast has taken the extreme step of disabling a major component of its antivirus product after a security researcher found a dangerous vulnerability that put all of the company's users at risk.

The security flaw was found in Avast's JavaScript engine, an internal component of the Avast antivirus that analyzes JavaScript code for malware before allowing it to execute in browsers or email clients.

Bringing asm.js to the Chakra JavaScript engine in Windows 10

Today we're excited to announce that we are moving asm.js to “In Development” at status.modern.ie. Support for asm.js has been one of the top 10 most-requested items at the IE Suggestion Box on UserVoice since we launched it in December.

Delivering an interoperable & spec compliant JavaScript engine with the capabilities and performance for modern experiences has been a key goal for us since the inception of Chakra. Bringing near-native performance for JavaScript code execution is a part of the same. We recently shared the details of some of the work we’ve done in Windows 10 to boost JavaScript execution speed in the Chakra engine.

Over the last few months we’ve taken a close look at asm.js as a technology, related technologies, and what they entail for the Web at large. While challenging to write by hand, asm.js is leveraged principally by transpiling C/C++ code to run on the Web platform, utilizing technologies such as WebGL and Web Audio. Asm.js is a clear step towards enabling near-native performance for the Web platform, which is why we’re excited to bring it to Chakra in an upcoming release.

Amongst other similar initiatives, asm.js as a technology has two key characteristics that we like:

First and obvious is the boost to JavaScript execution speed, which we’ve already talked about. We believe that asm.js and the work we do to enable asm.js has the potential to provide speed benefits to many more scenarios over a period of time.

Second but more importantly is the fact that asm.js is a pure subset of JavaScript and guarantees interoperability across platforms and browsers. This means that engines that support asm.js light up the new features, while engines that don’t will simply run with degraded performance. Since the beginning of Chakra, our team’s focus has always been to prioritize this approach to new functionality.

During this period, we’ve also been working closely with folks from the Firefox team who are working on asm.js, to learn from and partner with them to bring asm.js to the Chakra JavaScript engine.
We look forward to sharing more details and getting your feedback as we advance our implementation towards a preview state.

Protecting the computer (windows defender,avast, etc)?

Agreed with Firefox w/ Adblock Plus and NoScript. I suggest Antivir. Very trustworthy Antivirus and is less resource hogging the avast. Takes up about 40mb with guard enabled and 30mb with guard disabled.

How to uninstall Avast Antivirus if it does not show in the list of apps on the PC

I have Windows 10 Pro N, version 1803. For the last few days Windows is trying to install an update, but states the following: Uninstall Avast Antivirus now because it is not compatible with Windows 10. If I follow the steps: Settings > Apps and Features
; Avast does not show in the list of apps. I searched for it on my PC and found it on one of the drives. I tried to delete it, but the message still comes up, and therefore my Windows update cannot be completed. How do I get rid of Avast Antivirus?
