During the recent update of documentation, Intel revealed a problem, which was not known until then. The problem is present in every Skylake and Kaby Lake processors and also Xeon v5 and v6. As described by Debian operating system developers, who managed to isolate the issue and determine the condition of its occurrence, the processors exhibit dangerous and unpredictable behaviour when Hyper-Threading is activated.


Hyper-Threading is Intel’s proprietary simultaneous multithreading feature that improves parallel computation in microprocessors. Usually, an operating system recognises two logical cores for each physical processor core. Hyper-Threading allows to increase the number of logical cores and, hence, drastically improve parallel computation speed. Intel reports 15-30% better performance in comparison with an identical processor without this feature being activated.


After the problem was detected, Intel made an urgent announcement advising the users to deactivate Hyper-Threading in BIOS or UEFI. If the feature is kept enabled, users may experience unpredictable behaviour of programs and OS, distortion or even loss of data. It was highlighted, that the problem is not exclusive to Debian or other Linux systems. It can appear in any OS including Windows.


Intel is currently working on the solution. At the moment only Skylake family received the patch. In order to resolve the issue user must update BIOS/UEFI when the appropriate patch is released. To find out how to do this contact London computer repair service.

Creators Update distribution started on the 11th April, slightly over a month and a half ago. According to AdDuplex, a cross-promotion network for Windows Store apps, on the 22nd of May 2017, update number 1703 was detected on 18% of PCs running Windows 10. At the first glance, it may appear that it isn’t much. However, a month ago the number was 9,8%. That means that for the following 4 weeks the number doubled.


The majority still prefers Windows 10 version 1607, so-called Anniversary Update. Windows 10 version 1511 uses only 4,6% and original Windows 10, which is, by the way, is no longer supported, – 1,6%.


Yet, for somebody who’s not keeping up-to-date with news, it was difficult to miss the release of Creators Update. The message about the update is displayed in Windows Update window, which suggests you go to Microsoft’s website and manually download an upgrade assistant.


Why bother?


Now you can enjoy that crappy graphics app, Paint, in a whole new dimension – meet Paint 3D. But on a serious note, there are some pretty cool features too. Windows 10 enhances gaming experience: Game bar, GameDVR,  broadcasting, and Game Mode makes processing more productive and experience more pleasurable. Edge gets tabs, new extensions, bookstore and reading add-ons, and Cortana gets more updates. For people, who cares about own eyesight, finally, there is a Night Mode. And most importantly, a number of security features are there to protect you.


Last Friday, the 12th of may, the Internet drowned in a stream of news about a virus attack. The villain of this story was WannaCry (WnaCrypt0r 2.0) ransomware. It was the biggest attack attempted recently. According to a report from Avast, Internet security service, cases of infection with this malicious software were registered in 99 countries. The countries that suffered the most were Russia, Ukraine, and Taiwan.


The scale of this attack is marked by the fact that not only home-users became victims of it, but also entire companies, organisations, and departments. In the UK, NHS was affected to the extent that dozens of hospitals were not able to operate normally. The waiting hours were extended and urgent care was delayed. Nevertheless, Teresa May commented the occasion saying that there is no evidence of loss of sensitive data or exposure of important medical data. However, whether affected data had reserved copies or not is unclear. We just have to hope that the absence of evidence is not caused by inefficiency of the investigation.


Outside of the UK, virus affected the largest railroad operator in Germany, Deutsche Bahn, and automobile manufacturers such as Renault and Nissan. WannaCry penetrated ATMs in China, Spain, and Portugal. Other counties could not avoid the attack as well.


Unfortunately, the only way to recover from such attack is to restore data from a backup. Paying the offender is commonly discouraged, as you will be only supporting future criminal activity. You can get help with backup and disaster recovery from London IT Support.

ESET is in the guard as always. According to the company, a new malicious program is lurking in the dark corners of the Internet. This Trojan targets systems running on Android.


The malicious app, that contains Trojan Android/Charger.B, was found in Google Play store. It was distributed under the title Flashlight LED Widget. However, nothing stops cyber criminal to distribute the Trojan under any other titles and appearances. Besides Google Play the app can find its way to your device through the web other app stores.


After the installation the app requests administrator’s rights and the approval to open windows above other apps (for example, it works the same way Facebook Messenger works). After that the app sends the details about the device including a photo of the owner made with a frontal camera.


The Trojan was designed to steal passwords for banking and social media apps, such as Facebook and Instagram. When a user starts the application, like Facebook or Instagram, the malicious app creates a fake window above it that looks like a native window requesting user’s login details. The login details, passwords, and details of your bank cards entered in such window will be sent to cyber criminals.


It is easy to find the app. However, deleting it can be tricky. For that you will need to restart you phone boot in a safe mode. Contact our London IT Support centre for help.

Perhaps, you decided it’s time to sell your old MacBook and get a new one. Looking through the products available in the store it is easy to spot all the inconspicuous differences. The new models are way thinner, lighter, the keyboard feels a little bit weird, but there is a pretty touch bar above it, and, oh, the screen – so much better that any Apple product released before 2012. However, we bet one thing, we bet, you haven’t noticed.


That glass panel called trackpad looks, feels and sounds (almost) identical to what you had on your old MacBook Pro. However, it is deceiving. Until 2014, trackpads on Apple notebooks were pretty simple and similar: a hinge holds the thing in place, a button at the base gives you a “click”. Apple went crazy and decided to change this construction completely to simulate… what it always been doing before.


New Force Touch trackpad has no buttons. The click you hear is a super-fast vibration produced by electromagnets. As soon as you apply pressure, the sensors detect it and respond with a “buzz”. There is also a secondary click available by pressing a little bit harder on the trackpad. Beware, if your computer acts somewhat funny when you try to control the cursor, remember that there is now a secondary click. So you might need to be a little bit gentler with that glass panel. After fighting off some annoyance at the beginning, you may find that the secondary click can be actually useful. Additionally, you will be happy to discover that Force Touch trackpad registers your click equally well everywhere on its surface, unlike the old one that had to be pressed closer to the base to work.
