Giveaway: Free AVG Internet Security 2014 (1 Year)

AVG Internet Security 2014 provides you with protection against viruses, malware, spam, scams, phishing, and more. Plus it has additional features such as a firewall, internet accelerator, privacy protector, and more.

This is a 1-user 1-year license, for home and business use.

Please take note the way AVG runs freebies is they provide extended “trials” instead of licenses. This freebie is really a 365 day extended trial of AVG Internet Security 2014 instead of an actual 1-year license. In terms of features and protections, there are no differences between a trial and a real license — you get all the same features, updates, and protection. The difference arises in who can install it. If you have used AVG Internet Security in the past, then you won’t be able to install an extended trial and thus won’t be able to get this freebie. (If you haven’t used AVG Internet Security in the past, then you can get this freebie.) That is why AVG does it this way: they only want to attract new users with freebies, they don’t want to give a free year to existing users.

  • Free updates for one year
  • No free tech support
  • Cannot be installed or re-installed after this offer is over

VLSub Downloads Subtitles to VLC Player Automatically

It's not really hard to find subtitles online for your digital movie collection, but you can save a couple of steps with the VLSub extension for VLC media player.

After downloading the extension from Github, just drop it in the appropriate folder.

  • Windows: C:/Program Files/VideoLAN/VLC/lua/extensions/
  • OS X: /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
  • Linux: ~/.local/share/vlc/lua/extensions/

My Mac's VLC installation didn't have an extensions folder, but creating it manually worked just fine. Now, whenever you load up a movie, you can find VLsub in the View menu on Windows and Linux, and in VLC > Extensions on a Mac. The interface will automatically attempt to fill in the file name of your movie, but you can change it if necessary, and even add season and episode numbers for TV shows. VLSub will run a search for matching subtitle files, allowing you to pick the one you want and download it immediately. When you close the extension's window and start your movie again, the subtitles will appear automatically.

VLSub isn't doing anything you couldn't do yourself, but it can save you a minute or two to get you back to your movie sooner.

WiFi 802.11ac: What You Need To Know

Recently 802.11ac WiFi devices have started to emerge, but just what is WiFi 802.11ac and How fast is it? 802.11ac is a supercharged version of 802.11n, which is the current WiFi standard, offering link speeds ranging from 433 megabits-per-second (Mbps), through to multiple gigabits per second. To achieve these speeds which are dozens of times faster than 802.11n, 802.11ac works exclusively in the 5GHz band, uses a huge amount of bandwidth (80 or 160MHz) and operates in up to eight spatial streams (MIMO) and a utilizes technology called beamforming.

How 802.11ac works: At its core, 802.11ac is essentially an updated version of 802.11n, which itself introduced some very exciting technologies that brought massive speed boosts over 802.11a and g. Whereas 802.11n had support for four spatial streams (4×4 MIMO) and a channel width of 40MHz, 802.11ac can use eight spatial streams and has channels up to 80MHz wide, which can be combined to make 160MHz channels. Even if everything else remained the same, this means that 802.11n has 8x160MHz of spectral bandwidth to play with, vs. 4x40MHz, this is a huge difference that allows 802.11n to squeeze vast amounts of data across the spectrum.

802.11ac introduces 256-QAM modulation (an increase from 64-QAM in 802.11n), which fits 256 different signals over the same frequency by shifting each signal to a slightly different phase. In theory, this quadruples the spectral efficiency of 802.11ac over 802.11n. Spectral efficiency is a measure of how well a given wireless protocol/modulation/multiplexing technique uses the bandwidth available to it. In the 5GHz band, where channels are fairly wide (20MHz+), spectral efficiency is not so important; in the cellular or mobile bands though, channels are often 5MHz wide, which makes spectral efficiency very important.

802.11ac also introduces standardised beamforming (802.11n was non-standardized, which made interoperability an issue). Beamforming is essentially transmitting radio signals in such a way that they are directed at a specific device. This can increase throughput and also reduce power consumption. Beamforming can be done with smart antennae that physically move to track the device, or by modulating the amplitude and phase of the signals so that they destructively interfere with each other, leaving just a narrow, not-interfered beam. 802.11n uses this second method, which can be implemented by both routers and mobile devices.  Finally, 802.11ac is fully backwards compatible with 802.11n and 802.11g, this means you can buy an 802.11ac router today and it will work with your older WiFi devices.

Just how fast is WiFi 802.11ac?  Well there are two answers: the theoretical max speed that can be achieved in the laboratory, and the practical max speed that we will receive at home or in the office, surrounded by lots of signal altering obstacles.  The theoretical max speed of 802.11ac is eight 160MHz 256-QAM channels, each of which are capable of 866.7Mbps — a total of 6,933Mbps, this is slightly short of 7Gbps. That’s a transfer rate of 900 megabytes per second! which is more than you can squeeze down a SATA 3 link. In the real world, due to channel contention, you probably won’t get more than two or three 160MHz channels, so the max speed comes down to somewhere between 1.7Gbps and 2.5Gbps. Compare this with 802.11n’s max theoretical speed, which was 600Mbps.

Google Releases OEM Patch For Major Android Security Flaw

In a follow up to our recent report regarding how an Android Security Bug was found to let hackers gain system access, Google has released a fix to its Android original equipment manufacturers (OEM’s) for this bug, named: Android security bug 8219321 as unearthed by Bluebox Security in February this year. The flaw was confirmed from Google’s Android Communications Manager, Gina Scigliano, she said “a patch has been provided to our partners.” She also mentioned “Some OEMs, like Samsung, are already shipping the fix to the Android devices.”

The flaw in question will allow a hacker to turn a legitimate app into malicious files by modifying APK code without breaking the app’s cryptographic signature. In response to this, Google has already modified its Play Store’s app entry process to scan for the exploit so apps that have been modified using this vulnerability can no longer be distributed via the Play Store. Bluebox Security discovered the hole in Android’s code, which it claims could potentially affect 99 percent of Android devices, back in February and informed Google at that time. (but only made it public recently). Samsung’s Galaxy S4 was named then as one Android device that had already been patched, so it seems likely that this model is the device Gina Scigliano referred to when she cited Samsung as a manufacturer already shipping a fix. The problem for Android users is that even though Google has now in fact released a fix to its OEMs, they still have to wait for the maker of their particular handset to implement and ship the fix. This also poses another question, how long before their particular carrier tests it? Having to wait around to receive updates is a byproduct of the freeness and fragmentation of the Android sphere, still, it does not sound like this particular Android flaw has been widely exploited thus far. Scigliano has told ZDNet: “We have not seen any evidence of exploitation in Google Play or other app stores via our security scanning tools. Google Play scans for this issue and Verify Apps provides protection for Android users who download apps to their devices outside of Play.” But just because it has not been widely exploited yet, does not mean it will not be…does it?
