As described in Protecting users from potentially unwanted applications in Microsoft Edge - Microsoft Edge Blog, beginning with Microsoft Edge build 80.0.338.0, a new feature has been added to prevent downloads that may contain potentially unwanted apps (PUA) by blocking those apps from downloading. Although the feature is off by default, it can be enabled by doing the following:

1.  Open Settings.
2.  Select "Privacy and services".
3.  Scroll down to Services, and turn on "Block potentially unwanted apps".

In the event an app is mislabeled as PUA, it can be kept by tapping "…" at the bottom of the notice shown when an app is blocked and selecting "Keep" > "Keep anyway".

To report the app as safe, go to edge://downloads/, and select "Report this app as reputable", which will result in a redirect to the Edge feedback site.

Pale Moon has been updated to version 28.8.3 as a bugfix and security update.

The update includes two DiD ("Defense-in-Depth") updates. A DiD update is s a fix that does not apply to a (potentially) actively exploitable vulnerability in Pale Moon, but prevents future vulnerabilities caused by the same code, e.g. when surrounding code changes, exposing the problem, or when new attack vectors are discovered.

uBlock Origin Updater has become obsolete · Issue #112 · JustOff/ublock0-updater · GitHub

I'm pleased to announce that starting from version 1.16.4.17, uBlock Origin for Firefox legacy-based browsers can auto-update itself without any additional tricks. This also means that uBlock Origin Updater is becoming obsolete, and I'm going to make it so that it uninstalls itself on the next update.

I checked Add-ons and, sure enough, uBlock Origin Updater is no longer installed.

New optimizations boost performance in preview builds of Microsoft Edge - Microsoft Edge Blog
Quote
Starting with Microsoft Edge build 81.0.389.0 on 64-bit Windows 10, we’ve enabled new toolchain optimizations that should provide a substantial performance improvement in general browsing workloads.

We’ve measured an up to 13% performance improvement in the Speedometer 2.0 benchmark when compared to Microsoft Edge 79. Speedometer measures performance by simulating user interactions in a sample web app across a number of DOM APIs and popular JavaScript frameworks used by top sites, and is generally regarded as a good proxy for real-world performance across a number of different subsystems including the DOM, JavaScript engine, layout, and more.

It is important to note that the Microsoft test had no other tabs open and no apps -- by apps, I gather that includes ad-blockers, etc.  If you run a comparison, post your results as a reply.

It is Palindrome Day today and it won't happen again for 909 years!  The last time was 109 years ago -- 11/11/1111.  It is also the 33rd day of the year with 333 more days.

It is also Ground Hog Day and, according to the myth, since Punxsutawney Phil didn't see his shadow, we are supposed to have an early spring. 

As to Superbowl Sunday, no predictions from me on the outcome of the 49ers vs the Chiefs but feel free to claim your favorite to win.  :)

Published at Bleeping Computer as a guest post, Malwarebytes security researcher Pieter Arntz provides what for me and others who were around the forums during that time, a walk down memory lane in The Adware Families That Changed the Antivirus Industry.

Pale Moon has been updated to version 28.8.2 as a small bugfix and compatibility update.

From the Release Notes:

Changes/fixes:
  • Reverted the addition of JavaScript regular expression lookarounds since the implementation caused crashes. We'll have to revisit this later.
  • Fixed an issue where FTP servers would hang the browser if they were not sending answers according to the protocol specification.
  • Added a workaround for GitHub trying to enforce more Google-isms (which we don't support at this time) to browsers that identify as "Firefox-alike".
Update: To get the update now, select "Help" from the Pale Moon menu at the upper left of the browser window. Click About Pale Moon and Check for Updates.

Web News / Free Version of Avast Reportedly Marketing User Data
« on: January 27, 2020, 06:11:22 PM »
Although Avast implemented new security measures after Google and Mozilla removed temporarily removed the extensions, apparently that is not the end of the story.  Numerous tech articles have been posted today reporting that the anonymized web history data can still be picked apart and then linked back to individual Avast users.

Some of the articles published today:
Bottom line:  If you use the free version of Avast, you may want to consider a different antivirus.  (PC Mag has a collection of free A/V's here:  The Best Free Antivirus Protection for 2020 | PCMag).  For a licensed A/V, ESET remains a favorite.
