Virgin Media is urging hundreds of thousands of customers with its Super Hub 2 router to change their passwords after a Which? investigation uncovered a way for hackers to gain access to the device.

If the password for the router is not changed from its default there is a risk from hacking, but Virgin Media said the risk is small. Nevertheless, as a precautionary measure a password change is the advice for more than 800,000 users.

Part of the joy of shopping online is being able to easily compare prices at a number of retailers so you get the best price. If you prefer to get all of your goods from the same place, eBay has a new deal that you'll love -- price matching.

The offer covers items in the eBay Deals section, and price matching is carried out against Amazon.com, BestBuy.com, Walmart.com, HomeDepot.com, Target.com, Sears.com, Wayfair.com and Jet.com. But if you want to take advantage of the offer, you'll have to take careful note of the terms and conditions.

It's a common belief that anything that appears online is fair game for downloading and sharing, and this idea extends to Facebook profile pictures. Facebook has found that in India in particular there is great concern from users -- particularly woman -- about uploading a profile picture in case it is download and shared elsewhere.

Responding to this, the social network is trialling features that will grant users more control over their profile pictures. Facebook is not only introducing a new profile picture guard, but also encouraging people to add a design layer to their images to discourage misuse by others. If the trial proves successful, the feature will enjoy a wider rollout.

More than two thirds (67 percent) of small and medium-sized business in the UK see internet problems as their biggest productivity roadblock, new research has found.

According to a new report by Storey that surveyed 500 SME decision-makers across the UK, more than three quarters (76 percent) of businesses see productivity as a top priority in their office, while 69 percent are certain that improving office layout and design can do wonders on their productivity.

In recent weeks numerous Kodi add-ons have disappeared, and the popular site TVAddons also suffered the same fate. It had been presumed that the disappearances were related to a lawsuit taken out by Dish Network, and now the broadcaster has been granted subpoenas to help identify those developing the ZemTV Kodi addon and running the TVAddons website.

The subpoenas relate to a number of online services including Facebook and Twitter, and successfully identifying defendants will be key to the success with any lawsuits relating to copyright infringement.

A growing number of British consumers are using their neighbors' Wi-Fi, sometimes even without permission, because they can't afford their own.

This is according to a new report by Santander, which also says that the price of phone and broadband services has increased hugely over the past ten years.

Not content with splashing some cash on Whole Foods, Amazon is also spreading out into other new ventures. The latest is Prime Wardrobe, a new clothes shopping service for Prime subscribers that's currently in beta and offers the chance to "try before you buy."

The service ties in with Amazon Fashion, and it covers more than a million items of clothing. Users can select three or more items to have shipped out to them completely free of charge, and payment is only required for anything that's kept. Returns are free, and Amazon gives shoppers a full week to try out clothes.

Last month, the BBC announced plans to force iPlayer users to sign into their account in order to watch the catch-up service. The requirement is now rolling out, and this means that the option to skip sign-in is starting to vanish.

Visitors to the site are now greeted by a message that reads: "You now need to sign in to watch. It's quick & easy. And we'll keep you signed in." Without following the instruction to sign in -- which gives the BBC the opportunity to check for a valid TV license -- it is not possible to watch any programming.

ProtonMail has opened up its free VPN service to anyone who wants to use it. ProtonVPN was previously only available to a limited number of beta testers, but now everyone can secure their internet connection for free.

The company is best known for its encrypted email service, but the prospect of a free VPN tool will also be enticing to anyone who has concerns about privacy. It also provides a free way of bypassing internet restrictions that may be put in place by governments or ISPs.

Late last year Mozilla launched a private browser for iOS called Firefox Focus. Now the browser arrives on Android bringing the same privacy-focused internet experience to users of Google's mobile operating system.

When Mozilla talks about being privacy-focused, it does not just mean using Private Browsing. Firefox Focus is a completely separate browser which blocks trackers, analytics and ads, and also wipes your browsing history with a single tap. As well as improving privacy, Focus also speeds up web browsing and reduces data usage.

Back in March, Google was hit by criticism after it was discovered that its Restricted Mode filtered out many videos with LGBTQ content. A month later the company announced that it had fixed the problem that led to videos being "incorrectly filtered" and now, to coincide with Pride month, Google has revealed policy updates to Restricted Mode.

Google says that it has worked with LGBTQ creators and YouTube employees and will now explicitly allow content that was previously blocked, to be seen in Restricted Mode -- hoping to quieten any shouts of "censorship." The new policies mean that content such as "kissing at weddings, personal accounts of difficult events, and speaking out against discrimination" should no longer be caught in the net.

With its latest redesign, many people are complaining that Twitter has stepped back in time. If you are not a fan of the "circles and curves everywhere" look, you can -- with a little help -- avoid the redesign and stick with the way things were.

There's just one catch -- you have to be using Chrome. If this is already your web browser of choice, all you need to do is to install an extension built specifically to "remove Twitter's 'bubbly' redesign."

Wikileaks has released a batch of documents from the middle of 2012 revealing details of the CIA's CherryBlossom project. A joint venture with the Stanford Research Institute, the CherryBlossom files show how the agency can take remote control of routers and other networking devices from numerous manufacturers, transforming them into listening devices.

CherryBlossom also enables the CIA to interfere with both incoming and outgoing traffic. Passwords present little obstacle in many cases and the fact that remote infection is possible makes the implant very simple to install. The documents reveal how the CIA can home in on a target using information such as MAC address, email address, or even chat handles.

It has been a while since Twitter was treated to a new lick of paint, but that all changes today. A new look is rolling out, and "round" is the word that springs most readily to mind.

Think back to the look of the web around 15 years ago -- all rounded corners and the like -- and you're in the right ballpark. Online there are not only rounded buttons and round profile pictures, but also redesigned, wireframe icons. Mobile users are also treated to a new look.

Today marks the 30th anniversary of the GIF. The humble file format has -- after protracted arguments about how to pronounce the word -- come a long way. After years irritating people in the format of flashing animated ads, the images are now used to adorn messages with pithy memes and pertinent video clips.

GIFs in their current incarnation are supported by messaging tools and social platforms left, right and center, and after including a dedicated GIF button in Facebook Messenger, the social network is now rolling out the same feature in comments.
