For those who want to build a gaming rig without compromising performance, Amazon offers several discounted options. Three models featuring powerful processors, dedicated graphics cards, and high-quality screens have been gathered, allowing the consumer to compare and select the one best suited to their needs.

ASUS TUF Gaming A15 — Ryzen 7 + RTX 3050 + 144Hz Screen

The ASUS TUF Gaming A15 model is ideal for users looking for durability and fluidity during games. This laptop is equipped with an AMD Ryzen 7 processor, a GeForce RTX 3050 graphics card, 16GB of RAM, and a 512GB SSD. Its 15.6-inch IPS screen has a 144Hz refresh rate, which provides smoother images in competitive games. Furthermore, the Graphite Black finish gives the device a discreet and durable look.

Acer Nitro V15 — Core i7 + RTX 4050 + 16GB DDR5

The Acer Nitro V15 represents one of the most complete configurations listed. It integrates the Intel Core i7-13620H processor along with the 6GB GeForce RTX 4050 graphics card, 16GB of DDR5 RAM, and a 512GB NVMe SSD. The 15.6-inch screen with an IPS panel and Full HD resolution ensures excellent color reproduction, making it useful for both gaming and professional tasks. This model comes with Windows 11 Home pre-installed.

There is also the Acer Nitro V15 ANV15-52-7127 version, which uses the same Intel Core i7-13620H processor but features a different configuration, potentially being the ideal option depending on the buyer's usage profile. This model maintains the characteristic black design of the Nitro line, focusing on delivering good performance in a compact format. It is recommended to compare this version with the previous model to determine the best cost-benefit ratio for each situation.

It is important to note that offers on Amazon tend to change rapidly, and the stock of these discounted notebooks is usually limited. If any of the models have caught your interest, it is suggested to check the link immediately before the product goes out of promotion or sells out.

Developed in India, a new electric motorcycle called Avore EX2S features a 10.5 kW motor, capable of reaching 114 km/h, and a 5 kWh battery. This model was specifically designed to suit urban commuting and has a declared range of up to 260 km, as measured in a test cycle conducted in India.

The manufacturer equipped the EX2S with several advanced features, including a TFT display, smartphone connectivity functionality, and multiple riding mode options. Currently, the EX2S is exclusively aimed at the Indian market, with no plans for export to other nations.

The powertrain, which operates with permanent and synchronous magnets, generates 10.5 kW of power, equivalent to approximately 14 horsepower. Furthermore, it offers a declared torque of 250 Nm at the wheel. According to data provided by the manufacturer itself, the EX2S can accelerate from 0 to 40 km/h in just 2.8 seconds and reach its top speed of 114 km/h.

The 5 kWh battery is responsible for the announced range of 260 km under the IDC cycle used in India. However, it is estimated that the real range during daily use may be significantly lower, approaching 130 km, which still represents considerable autonomy for urban traffic.

For charging, the EX2S incorporates a 1.5 kW integrated charger, allowing the user to simply connect it to a residential outlet. Avore reports that the battery can charge from 20% to 80% in about two hours, while a full charge takes approximately four hours.

Another notable aspect is that the battery is structured in modules. According to the company, this modular architecture aids both in more balanced weight distribution and in managing the unit's temperature.

The technical attributes disclosed by the manufacturer include a 7-inch TFT display, which shows navigation and riding information, as well as the possibility of connecting to a smartphone. This integration allows for the use of features such as safety alerts, diagnostics, and geofencing. There are also different riding modes, such as SYFT Mode, which simulates gear shifting of a traditional motorcycle, even though it is an electric vehicle.

Considering that India sells over 20 million motorcycles and scooters annually, this justifies Avore's interest in creating a model specific to this large market. Despite there being no indication that the company plans to take the EX2S to other countries, the project consolidates performance, declared range, and digital functionalities in a bike geared towards daily use. The price of the EX2S is ₹169,999, which corresponds to about R$ 9.7 thousand.

Microsoft has encountered a new security issue in the Windows operating system related to a vulnerability named ShieldBreak. According to TechCrunch, security researcher Nightmare Eclipse disclosed information about the new vulnerability in recent versions of Windows following disagreements with Microsoft regarding previous zero-day vulnerability disclosures.

This threat is particularly prevalent for residents of South Africa, as many small business office, school, home PCs, and desktop computers still run on Windows. Therefore, if you receive a mysterious application this week, the correct response would be to treat it as an investment plan sent via WhatsApp from an unreliable relative.

The ShieldBreak vulnerability targets Windows Defender, the built-in antivirus engine of Windows. A successful attack allows an attacker to move from low-level user access to full control over the device and data. In a post dated August 11, 2026, Nightmare Eclipse dubbed it 'New 0day in Defender' and provided links to public ShieldBreak repositories. The proof of concept was released as a Windows application, which requires the user to run it to activate the exploit.

Security researcher Will Dormann reported that he conducted brief testing of ShieldBreak, noting that 'Defender must be enabled for the exploit to work.' Dormann specified that this flaw applies to Windows 10, Windows 11, including the latest version 25H2, as well as Windows Server 2025.

As of now, Microsoft has not released a fix for ShieldBreak. A Microsoft representative told TechCrunch that the company 'is aware of the claimed vulnerability and is actively investigating the validity and potential applicability of these claims.' The disclosure occurred after Microsoft's regular August update (Patch Tuesday). Krebs on Security reported that in this month, Microsoft released updates for at least 398 vulnerabilities in Windows and supported software, including one weakness that is already being actively exploited, and two others that were publicly described before the patch release.

The conflict behind ShieldBreak had been brewing for months. It is reported that Nightmare Eclipse published details of several flaws in Microsoft products, including Windows, and that some earlier Windows flaws were subsequently used in real attacks. In May, Microsoft did not name Nightmare Eclipse in the MSRC blog post, but criticized uncoordinated disclosures, stating that a number of zero-day vulnerabilities were made public without prior exchange of details with Microsoft. The company emphasized that uncoordinated disclosure, placing proof-of-concept code for unpatched flaws into the hands of attackers, 'is never justified and has real consequences.'

The same post stated that the Microsoft Digital Crime Unit would continue to prosecute attackers and 'those who facilitate their criminal activities,' coordinating with law enforcement when necessary. Microsoft later retracted comments in a social media post, although the original blog remains published.

For the average user, the practical advice is simple: keep Windows Update enabled. Restart when the system prompts for an update. Do not download random executables just because someone online claims they prove a certain point. Your laptop does not care about ethical debates; it just needs a patch.
