7 Things to Look Out For When Buying A Computer

Azuka awoke with a blinding headache on Saturday. She held her throbbing skull in both hands and wondered what to do next. She wasn’t ill, but after six awful nights spent agonizing over how to avoid another big mistake, her nerve endings were on fire, screaming for relief.

She had paid dearly for buying her last laptop on a whim (she was swayed by the size and colour) but discovered a little too late that it was dysfunctional, out of date and slow.

Thousands of Naira later and after dozens of visits to repair shops, she had learnt her lesson, but now she had no idea where to start, apart from hopping into the first taxi and heading to the closest computer hardware store at Otigba.

Buying a new laptop computer can be both frustrating and expensive. Technology is growing with times, a sign of transformation.

Same can be said in the computer world, previously we used to be happy with just basic PC but now the game has changed with the people wanting more out of their PC.

Luckily, getting a new laptop need not result in moans before or after purchase, as there are a couple of things everyone, including dyed-in-the wool technophobes, can learn to look out for, without needing to present a systems engineering certificate.

According to Chuks, an ICT consultant at the computer village who has been in the business for over 10 years, one needs to read beneath the incomprehensible computer-geek gobbledegook available all over the internet and stick to brass tacks. Here are 7 things to look out for when buying a computer;

Size and Weight
Heavy laptops kill mobility. In 2011, computer processor maker Intel began pushing an Ultrabook category that focuses on lightweight systems — usually weighing about 3 pounds (1.3 kilograms) — to make use of its ultra-low voltage CPUs.

Ultrabooks do away with disc drives and focus on portability, long battery life. These laptops aren’t powerful enough for some users, and do away with a disc drive others find important, but they demonstrate a trend towards lightweight notebooks that are extremely portable.

The best way to get around the weight issue is to select a computer that makes weight and size a priority concern.

The downside however is that such computers are usually more expensive, which largely depends on what brand you drawn to.

Storage and Memory
Now, there are probably so many users who detest keeping an eye out for the memory size. It is however a necessary item on the purchase checklist if you want to avoid your computer freezing like Azuka’s which froze every three hours of every other day.

Storage space may not be a big concern for you — if you not a heavy user and don’t plan to load a computer up with gigabytes of music and video, an  SSD or small HDD will suit you just fine. Random access memory (RAM) is a different story.

Every piece of software running on a computer and the operating system itself (usually meaning Windows) stores data in RAM to function. The more RAM you have, the better.

Google your laptop to see if owners have found it easy to add additional RAM or swap out the hard drive. Either of those upgrades could give your laptop an extended lease on life sometime down the road, but some casings are much easier to open up than others.

Battery Life
The Battery Life is directly or indirectly the first need of any user. If the device’s battery system is of poor quality, then one will face many inevitable problems.

Laptop computing is all about mobility, and battery life is perhaps the most crucial consideration when picking a laptop that’s going to be used regularly on the go.

As laptops get slimmer and designers pay more attention to making them sleek and compact, more and more systems use integrated non-removable batteries.

The very first thing to do as a customer is, first ask about the Laptop’s battery life. So one should check and enquire about maximum support the Laptop’s battery will give, when being used in full capacity.

The size and power of a laptop affects how much room there is in the body for a battery (and how quickly it’s drained). It is in your best interest to find that size and weight sweet spot when purchasing a laptop.

Processors and Graphics
The simplest way to explain the processor is that it’s the brain of the machine. If you want a fast computer that boots up programs in a flash, completes tasks as soon as you start them, and doesn’t keep you waiting, then you want the strongest processor available — and who doesn’t? You just have to know what you’re looking at when you see a processor’s details.

The key to selecting processors is in the number of cores and the speed (labelled in GHz or Gigahertz) of the processor.

The speed of the chip will tell you how much data it can process in how much time, so the bigger the number, the better. (e.g. a single-core 2GHz processor is a lot slower than a four-core 2GHz processor).

Multiple cores can also help with multi-tasking, as each can be working on different tasks. If you don’t use a lot of programs at the same time, you may be content with just one or two cores and don’t need to spend a little extra money to snag a few more.

Make sure to ask how many cores are on the chip and what the clock speed is.

Two computers might both say they have an Intel i5 chip, but the number of models that go into the group are many, and their speeds and core counts can be leagues apart.

If you want to get into really nitty-gritty bits of the processor, you can compare a number of different CPUs to see if you’re getting the best one, and even see if you’re getting the best for your money.

So whether it be for work or play, the simple rule to remember when buying a computer is: the more/higher the processor, the better for you.

Ports and Expandability
Every computer user is familiar with the USB port, but not everyone is aware that a much faster update to the standard, USB 3.0, is slowly spreading through the computer industry.

USB 3.0 can be 10 times faster than its predecessor in real-world usage, delivering transfer speeds of up to 400 megabytes per second [source: EverythingUSB].

Even if you don’t own any USB 3.0 hardware right now, consider future proofing when buying a new laptop. You might be really thankful you have that USB 3.0 port down the road.

There are other ports to consider as well. Do you want HDMI to output video to a TV? Do you need an SD card slot for downloading digital camera photos to your laptop? Will you need an Ethernet port for Internet or will a laptop’s built-in Wi-Fi connection be enough?

Warranty
Being careful with your laptop is the best way to protect it. Picking a warranty isn’t an easy decision, either. If you’re clumsy and accident prone (or paranoid), opting for a long warranty will put your mind at ease.

But it will also cost you more, depending on the kind of coverage you choose. Total coverage packages for accidents are expensive, but you’ll be glad you have it if you accidentally step on your screen and break the LCD.

There are companies that offer free technical support for a year or less, whatever you are getting, start by trying to understand the terms and conditions stated in the warrant policy when deciding to purchase a computer. And there’s nothing wrong with going for the cheapest limited warranty you can — just don’t drop your new laptop!

Price
Everyone has a budget, and one should buy Laptops bearing same in mind. For instance, if your budget is 25, 000 and you are dreaming of a device which costs 50, 000, this is calling for avoidable debts.

So, in such case, you should concentrate on main functions needed for your use. In cheap price you can’t enjoy latest technology but can surely seek out functions which are basic and required one.

New systems usually come out shortly after Intel launches new processors. Look up review for laptops. See a model that was highly rated but came out nine months ago? A newer version will probably be along within a few months. Don’t buy a laptop months into its release cycle unless you’re shopping on a budget and spy a killer deal.

Buying a laptop isn’t always simple. After all, there are myriad factors to consider, but by arming yourself with knowledge, you can avoid Azuka’s migraine and enjoy easy clicking for much longer.

Kaspersky Reports 15% Growth in Malicious email Attacks in 2025

Published

on

Kindly share this post

According to Kaspersky telemetry, almost every second email – 44.99% of global traffic – was spam in 2025. Spam consists not only of unsolicited emails, but can also include various email threats such as scam, phishing and malware.

In 2025, individuals and corporate users encountered over 144 million malicious and potentially unwanted email attachments, representing a 15% increase compared to the previous year figures.

In 2025, APAC had the largest share of email antivirus detections: it reached 30%, followed by Europe with 21%. Next came Latin America (16%) and the Middle East (15%), Russia and CIS (12%) and Africa (6%). As for individual countries, China had the highest rate of malicious and potentially unwanted email attachments, with the share of email antivirus detections of 14%. Russia ranked second (11%), followed by Mexico (8%), Spain (8%) and Turkey (5%).

Email antivirus detections peaked moderately in June, July and November.

Key trends in email spam and phishing

Kaspersky’s annual analysis has also identified several persistent trends in the email spam and phishing threat landscape that are expected to continue into 2026:

  • Combination of various communication channels. Attackers lure email users into switching to messengers or calling fraudulent phone numbers. For instance, scam investment mailings may redirect victims to fake websites, where they are asked to provide their contact information, and then cybercriminals will follow up with a phone call.
  • Usage of diverse evasion techniques in phishing and malicious emails. Threat actors frequently try to disguise phishing URLs, for example, with the help of link protection services and QR codes. These QR codes are often embedded directly in email bodies or within PDF attachments, which not only conceals phishing links but also encourages users to scan them on mobile devices, potentially exploiting weaker security measures than corporate PCs.
  • Mailings exploiting diverse legitimate platforms. For example, Kaspersky experts discovered a fraudulent tactic that abuses OpenAI’s organisation creation and team invitation features to send spam emails from legitimate OpenAI addresses, potentially tricking users into clicking scam links or dialing fraudulent phone numbers. Additionally, a calendar-based phishing scheme, which originated in the late 2010s, resurfaced last year with a focus on corporate users.
  • Refining tactics in business email compromise (BEC) attacks. In 2025 attackers attempted to become even more persuasive by incorporating fake forwarded emails into their correspondence. These emails lacked thread-index headers or other headers, making it difficult to verify their legitimacy within an email conversation. 

“Email phishing shouldn’t be underestimated. Our report reveals that one in ten business attacks starts with phishing, with a significant proportion being Advanced Persistent Threats (APTs). In 2025, we saw an increase in the sophistication of targeted email attacks. Even the smallest details are meticulously crafted in these malicious campaigns, including the composition of sender addresses and the tailoring of content to real corporate events and processes.

“The commodification of generative AI has significantly amplified this threat, enabling attackers to craft convincing, personalised phishing messages at scale with minimal effort, automatically adapting tone, language and context to specific targets,” comments Roman Dedenok, anti-spam expert at Kaspersky.

Cybersafe Foundation Partners Google to Strengthen Cybersecurity Among CCIs in Africa

Published

The Cybersafe Foundation has collaborated with Google in strengthening cybersecurity resilience among Critical Community Institutions across Nigeria, Kenya, Ghana and South Africa with the launch of Resilio Africa.

 

Speaking at the event in Lagos, Confidence Staveley, Executive Director of the Cybersafe Foundation, noted that while many organizations recognize the risks posed by cyber threats, conversations often stall when it comes to implementation.

“Across Africa, Critical Community Institutions are facing an increase in cyberattacks often without the capacity to defend themselves. Sub-Saharan Africa is now experiencing some of the most aggressive cyber activity globally. According to a threat report by Kaspersky, the region recorded over 42 million web attacks and 95 million malware-based, on-device attacks in just the first half of 2025.

“What’s especially concerning is the nature of these attacks: spyware, password stealers, and backdoor tools dominate, with password-stealing malware increasing by more than 60%.

“In East Africa, the scale is even more stark. Kenya alone recorded 2.5 billion cyber-threat events in Q1 2025, driven largely by phishing, mobile money fraud, and misconfigured cloud services,” she stated.

According to her, the primary barrier is not a lack of willingness but limited financial capacity to fund adequate cybersecurity measures.

“The conversation drops off at the point of taking action,” she said, explaining that many institutions lack the budgets required to implement robust security systems.

She disclosed that the programme’s provision of 10,000 hours of expert cybersecurity consultation—offered at no cost to participating institutions would ordinarily represent services valued at over one million dollars. The support, funded through a grant from Google.org, will be delivered by specialists across four participating countries.

Staveley reaffirmed that the Cybersafe Foundation remains a non-profit organization focused on supporting vulnerable communities and institutions, and described Resilio Africa as a strategic intervention aimed at strengthening digital trust across the continent, ensuring that commerce and essential public services can operate securely in an increasingly digital society.

Although the programme currently covers Nigeria, Kenya, Ghana and South Africa, Staveley acknowledged that the cybersecurity challenges extend far beyond those countries, and expressed hope that demonstrated impact from the initial phase would attract additional funding to scale the initiative to more than the 200 critical community institutions currently targeted, including underserved Francophone nations.

“This work is free to the organizations we serve, but it is not free to deliver,” she noted, underscoring the need for sustainable funding.

Explaining her personal motivation, Staveley said she views Africa’s cybersecurity challenges as opportunities for impact. Despite her engagements on global platforms, she emphasized her commitment to Nigeria and the broader African continent, describing the region as both home and a priority.

She pointed to a growing mismatch between rising cyber threats and limited investment in cybersecurity infrastructure, arguing that bridging this gap is central to the Foundation’s mission.

Staveley also clarified that Resilio Africa will not collect or own user data from participating institutions. Instead, the programme will focus on strengthening internal controls, building capacity and guiding organizations toward improved data protection practices.

With Resilio Africa now underway, the Cybersafe Foundation aims to demonstrate how targeted support for critical community institutions can enhance digital security and build long-term resilience across Africa’s rapidly expanding digital economy.

Kaspersky Brings more Transparency to Threat Detection with New Hunt Hub

Published

on

Kindly share this post

Kaspersky has announced a major update to its Threat Intelligence Portal (TIP), introducing a new Hunt Hub section alongside an enhanced MITRE ATT&CK coverage map and a significantly expanded vulnerabilities database.

The update strengthens organisations’ ability to investigate threats, understand adversary behaviour, and proactively monitor the most relevant risks across their environments.

According to the Kaspersky Security Bulletin 2025 report, Kaspersky’s detection systems discovered an average of 500,000 malicious files per day in 2025, marking a 7% increase compared to the previous year. As cyberattacks become more sophisticated and frequent, security teams need more than alerts – they need clarity.

The newly launched Hunt Hub is designed to address growing market demand for greater transparency and deeper insight into how modern detection technologies work. Integrated into the Threat Landscape section of the Threat Intelligence Portal, Hunt Hub provides centralised access to Kaspersky’s threat hunting expertise and detection knowledge.

Hunt Hub includes Kaspersky Next EDR Expert hunts, also known as indicators of attack (IoA) or detection rules. All portal users can explore the catalogue of hunts and their descriptions, while Kaspersky Next EDR Expert customers gain extended access to detailed recommendations and detection logic presented in a convenient, SIGMA-like format. Each hunt is mapped to relevant MITRE ATT&CK tactics and techniques and linked to known threat actors, giving analysts clear context behind every detection.

By making detection logic visible and structured, Hunt Hub effectively removes the “black box” from threat detection. It allows security teams not only to respond to alerts, but also to understand why a detection was triggered and which threat it is designed to uncover – improving trust in security technologies and increasing the efficiency of threat investigation processes.

As part of the update, the MITRE ATT&CK coverage map within the Threat Landscape has been significantly enhanced. The portal now brings together product coverage across SIEM, EDR, NDR and Sandbox solutions, MITRE ATT&CK techniques with scoring, coverage percentages, and related Kaspersky Next EDR Expert hunts in a single, unified view. This enables organisations to assess how well their security stack covers relevant attack techniques and identify potential gaps in protection.

The Vulnerabilities section has also been expanded, with the CVE database now covering nearly 300,000 vulnerabilities. In addition, the portal provides more detailed information on vulnerabilities that have been exploited in real-world attacks, helping organisations prioritise remediation efforts based on actual threat activity.

“With the launch of Hunt Hub in the Kaspersky Threat Intelligence Portal, we are opening up our detection expertise and giving analysts clear visibility into how and why threats are detected. This transparency helps organisations move from reactive alert handling to informed threat hunting and proactive risk management,” comments Nikita Nazarov, Head of Threat Exploration at Kaspersky.
