Critical bug on WebAdvisor chrome extension

Version 8.1.0.4679 has a bug in one of scripts: page_crypto_mining.js at line 23:525 (minified version). There is TypeError: 's.startsWith is not a function'. It breaks page scripts on different websites which use arraybuffer. I think this is critical bug.

Good to hear that you are working on a solution. I've tried to contact via support chat, but with no success - I was not able to convince your support that this problem is crticial and every user of this extensions suffers from it. 

I'm waiting for the update!

McAfee is aware of the issue and working towards the resolution. We will keep you update once the issue gets resolved.
Workaround:
1.  Kindly use an alternate browser like Firefox, Safari, Edge. 
2.  If issue persists on alt browser, uninstall web advisor and reinstall from firefox/edge. Do not install from chrome web store
3.  If you have only chrome browser, disable web advisor.

Re: Critical bug on WebAdvisor chrome extension

An error exists in the override of XMLHttpRequest.prototype.open in page_crypto_mining.js.

XMLHttpRequest.prototype.open originally takes five arguments, but it takes only two.
As an example, if the caller specifies false for the third argument, it is ignored by the override by the WebAdvisor, causing the request to fail to wait for motive and causing problems for the website.
