Specifically the problem comes if the software is from version 19.5.4444.567 or earlier. (Source: techradar.com ) Since Avast! also owns AVG, the version number is the same for both engines.

How to Fix: Permanently Disable WiFi on Windows 10

Infopackets Reader 'JustRosy' writes: " Dear Dennis, I have a laptop that I use daily, and for security reasons I want my WiFi permanently disabled in Windows 10 . Unfortunately my Windows 10 laptop WiFi does not have an 'on / off' switch which ... would disable my WiFi permanently. Instead, I have been using Windows 10 "airplane mode" to disable the WiFi, but this doesn't work 100% of the time because my WiFi seems to activate spontaneously. I am super paranoid about having a WiFi connection because I don't believe there is a 100% secure WiFi, and therefore I don't ever want to use WiFi on my ... (view more)

New 'LiFi' Gets 8 Gigabit Speed; Faster than WiFi, 5G

Light could be the key to solving one of the big problems of faster mobile Internet. But the technology, which uses spotlights to send out signals, has some limited range of uses. The technology developed by pureLiFi works on a simple principle: ... rather than using radio waves to transmit data (as does WiFi), it uses light waves. A demo of the system uses ceiling spotlights which blast out light in a cone shape. To the human eye it looks like an ordinary constant light supply. In fact it's actually flickering at incredibly high speeds to create a pattern. 5G Signals Hurt By Walls A plug-in ' ... (view more)

Explained: Absolute Best way to Limit Data on Android

Infopackets Reader Sam G. writes: " Dear Dennis, I work from home and also own an Android smartphone, which I use to communicate (via text messages) with friends and family. Because I am home all the time, I use WiFi on my phone instead of data. ... Therefore, I purchased a very cheap 'pay as you go' data plan for when I'm away from the office. The problem is that my data is being eaten away by apps on my phone whenever I'm on the go. I have tried disabling 'background data' on my Android phone to limit which apps can use data, but this is incredibly time consuming because each data permission is ... (view more)
