Name: Kaspersky Standard, 5-Devices 1-Year,KL1041UCAFS
SKU: 35868
Availability: InStock

Five devices. One licence. Zero compromises.

In today’s hyper-connected world, the average household operates five or more internet-connected devices simultaneously — and every single one of them is a potential entry point for cybercriminals, ransomware operators, and data thieves who are working around the clock to exploit any unprotected gap they can find. The Kaspersky Standard 5-Device 1-Year Antivirus Protection (KL1041UCAFS) is the comprehensive, award-winning cybersecurity solution that closes every one of those gaps — protecting your entire digital ecosystem under a single, cost-effective licence that covers Windows PCs, Macs, Android smartphones, and iOS devices all at once.

This is not partial protection. This is not a compromise between coverage and cost. This is complete, award-winning, real-time security for every device your household or small business depends on — powered by one of the world’s most sophisticated cybersecurity platforms and backed by over three decades of frontline threat intelligence expertise.

Five devices fully protected. Every threat actively blocked. Every piece of your digital life comprehensively defended — for a full twelve months from the moment you activate.

Why Five Devices Changes Everything About Your Cybersecurity Strategy

Most households discover their protection gap the hard way — after a ransomware attack encrypts the family laptop, after a banking trojan silently harvests credentials from an unprotected Android phone, or after a phishing attack compromises the email account accessed across multiple devices. The uncomfortable truth is that protecting one or two devices while leaving others exposed is the same as locking your front door and leaving every window open.

The Kaspersky Standard 5-Device licence (KL1041UCAFS) was designed specifically to eliminate that vulnerability — giving households, remote-working professionals, and small business teams the ability to bring every active device under the umbrella of one of the world’s most tested and trusted cybersecurity platforms.

Think about the devices in your life right now: your primary laptop, your desktop, your partner’s laptop, your Android smartphone, your teenager’s tablet. That’s five devices — five potential attack surfaces — and with the KL1041UCAFS licence, every single one of them receives the same comprehensive, real-time, cloud-powered protection that has earned Kaspersky its position as a global cybersecurity leader for over thirty years.

When every device is protected, your entire digital life is protected. That is the power of five.

Key Features & Protection Capabilities

Real-Time Antivirus & Anti-Malware — Relentless, Always-On Defence Across Every Device

Continuous Real-Time Scanning: Every file opened, every application launched, every process executed is monitored in real time across all five covered devices — threats are identified and blocked before they can execute, not after damage has been done
Multi-Layer Threat Detection: Defends against the complete spectrum of modern malware — viruses, worms, trojans, rootkits, spyware, adware, ransomware, cryptominers, fileless malware, and zero-day exploits
Kaspersky Security Network (KSN): Your protected devices connect to Kaspersky’s global cloud threat intelligence database of over 600 million known and emerging threats — enabling detection of brand-new malware strains within minutes of their first appearance anywhere in the world
Behavioural Analysis Engine: Goes beyond signature-based detection to monitor the actual behaviour of running applications in real time — identifying and terminating malicious processes that disguise themselves as legitimate software through suspicious patterns of system interaction
Heuristic Detection: Identifies new, previously unseen malware variants by analysing code structure and behavioural characteristics — closing the detection gap that signature-only scanners leave wide open
Automatic Threat Definition Updates: Kaspersky’s threat databases are updated continuously throughout every day — ensuring your protection keeps pace with the relentless evolution of the threat landscape

Advanced Anti-Ransomware Protection — Your Files Are Never Held Hostage

Multi-Stage Ransomware Blocking: Detects and terminates ransomware at the earliest possible stage of the attack chain — before encryption begins, before your files are compromised, before the ransom demand appears
System Rollback Technology: If ransomware activity is detected after any files have been modified, Kaspersky’s rollback engine reverses all malicious changes — restoring affected files to their exact pre-attack state
Protected Folders: Designate critical folders containing your irreplaceable documents, family photos, financial records, and work files as protected — blocking any unauthorised application from modifying, encrypting, or deleting their contents
Ransomware-Specific Behaviour Monitoring: Continuously watches for the specific behavioural patterns — rapid file enumeration, mass encryption activity, shadow copy deletion — that characterise ransomware attacks, triggering immediate intervention the moment they are detected
Crypto-Miner Detection: Identifies and terminates cryptocurrency mining malware that silently hijacks your device’s processing power and drives up electricity consumption without your knowledge

Intelligent Anti-Phishing & Safe Browsing — Protected at Every Click

Real-Time URL Analysis: Every link you click is checked against Kaspersky’s continuously updated database of malicious URLs — dangerous websites are blocked before they load, not after your credentials have already been submitted
Advanced Phishing Detection: Combines URL reputation data, SSL certificate analysis, page content inspection, and behavioural signals to identify phishing pages — including sophisticated, newly created phishing sites that haven’t yet appeared in any blacklist database
Safe Search: Integrates directly with Google, Bing, Yahoo, and other major search engines to flag dangerous search results — warning you visually before you click on a compromised or malicious link
Anti-Banner Technology: Blocks malicious advertising banners that serve as delivery mechanisms for drive-by downloads, tracking scripts, and browser-based exploit kits
Download Scanner: Every file downloaded from the internet is scanned in real time — malicious content is quarantined before it reaches your device’s file system, regardless of the source

Network Attack Blocker & Wi-Fi Security — Protecting Your Connection, Not Just Your Devices

Intrusion Prevention System (IPS): Continuously monitors incoming network traffic for exploit attempts, port scanning, vulnerability probes, and brute-force attack patterns — blocking network-based attacks at the connection level before they reach the operating system
Public Wi-Fi Protection: Automatically detects when your device connects to an unsecured or potentially compromised public Wi-Fi network — alerting you to the risk and activating additional protective measures to safeguard your data on café, airport, hotel, and co-working space networks
Firewall Augmentation: Works in concert with your device’s built-in firewall to monitor and intelligently control inbound and outbound network connections — preventing unauthorised applications from establishing remote server communications or exfiltrating your data

Performance-Optimised Design — Maximum Security, Minimum System Impact

Ultra-Low System Footprint: Consistently rated among the least performance-impacting antivirus solutions in independent AV-TEST benchmarks — delivering comprehensive multi-layer protection without slowing down your device, your applications, or your user experience
Gaming Mode: Automatically detects full-screen gaming or media sessions and suspends non-critical notifications and background tasks — maintaining full protection while delivering an uninterrupted gaming or viewing experience
Silent Mode: Suppresses all non-critical alerts and background scanning activity during presentations, video conferences, and focused work sessions — invisible protection when you need concentration
Smart Scan Scheduling: Configure intensive deep scans to run automatically during off-peak hours — overnight or during lunch breaks — so comprehensive scanning never interferes with productive work time
Rapid Quick Scan: Targeted scans of the highest-risk system areas complete in under 2 minutes — delivering fast security assurance without committing to a full system scan

Who Needs the Kaspersky Standard 5-Device Licence?

Families with Multiple Connected Members

The moment your household has more than two or three active internet users, device coverage becomes a family protection issue rather than an individual one. Every teenager browsing social media on a shared laptop, every parent managing online banking on their smartphone, every child using a tablet for homework — each represents a potential attack vector. The 5-device KL1041UCAFS licence ensures that no family member’s device is the weak link that exposes the entire household network to compromise.

Remote Working Professionals & Digital Nomads

Working from home or travelling for work means operating across multiple devices on networks you don’t control — home broadband, hotel Wi-Fi, co-working space networks, and mobile data connections. Remote workers typically operate across three to five devices spanning work and personal use, creating a complex security footprint that demands comprehensive, multi-device protection. Kaspersky Standard covers every device in your professional and personal arsenal with the same award-winning protection.

Small Business Teams Without a Dedicated IT Department

For small businesses operating with three to five workstations and key team members who also use personal mobile devices for work communications, the 5-device Kaspersky Standard licence delivers enterprise-calibre endpoint protection at a fraction of the cost of a business security suite. Protect your customer data, financial records, and business communications without the overhead of an enterprise security platform.

Power Users & Tech-Enthusiast Households

Tech-savvy households that maintain multiple active devices — desktop PCs, gaming laptops, MacBooks, Android phones, and tablets across family members — have a device count that quickly exceeds what a 3-device licence can cover. The 5-device licence is the natural fit for households where five connected devices is not unusual — it’s the norm.

Households with Elderly or Vulnerable Users

Older users and those less experienced with digital threats are disproportionately targeted by phishing attacks, tech support scams, and malware disguised as legitimate software. If you manage or provide technical support for a household with elderly family members, the 5-device licence allows you to extend the same robust Kaspersky protection to their devices — giving the entire extended family the protection they need, without requiring them to manage it themselves.

Solving Your Most Critical Cybersecurity Questions

❓ “Why do I need 5-device coverage when I only think about protecting my main laptop?”

This is the most common — and most dangerous — misconception in consumer cybersecurity. Your main laptop may be well-protected, but if your partner’s phone, your teenager’s tablet, or your home desktop is unprotected and connects to the same home network, that unprotected device can serve as an entry point for malware that spreads laterally across your entire network — ultimately compromising even your well-protected primary device. Complete protection means protecting every device in your ecosystem, not just the one you think of as your most important.

❓ “Is there a meaningful difference between the 3-device and 5-device Kaspersky Standard licences beyond device count?”

The protection technology, feature set, and software are identical across both licence tiers — the KL1041UCAFS 5-device licence delivers the same award-winning Kaspersky Standard protection as the 3-device version, simply extended to cover two additional devices. For households and small teams where five devices is the reality of daily digital life, the 5-device licence is simply the right-sized solution — and the per-device cost is typically lower than purchasing two separate 3-device licences.

❓ “Will running Kaspersky on five devices simultaneously cause performance issues?”

No. Kaspersky Standard is one of the most performance-efficient antivirus solutions in the industry — AV-TEST consistently rates it among the lowest-impact security products in its performance benchmark tests. Each installation operates independently on its respective device, consuming minimal system resources. Whether you have one device or five devices running Kaspersky Standard simultaneously, each individual device’s performance is unaffected by the others. On modern hardware with multi-core processors and 8GB or more of RAM, Kaspersky Standard’s presence is essentially imperceptible during normal use.

❓ “My devices run different operating systems — Windows, Mac, and Android. Will one licence cover all of them?”

Absolutely — and this cross-platform flexibility is one of the most compelling advantages of the KL1041UCAFS licence. Your five covered devices can be any combination of Windows, macOS, Android, and iOS — there is no restriction on mixing platforms. Each platform receives the Kaspersky Standard protection features appropriate to its operating system, all managed through a single Kaspersky account via the My Kaspersky online portal.

❓ “How do I manage protection across five different devices?”

The My Kaspersky online management portal provides a single dashboard from which you can monitor the protection status of all five covered devices, check that threat databases are current, review detected threats, and manage licence activation — from any browser, on any device. You can also send remote installation links to family members’ devices, making it easy to deploy protection across a household without needing physical access to each device.

❓ “What happens if I get a new device during my licence year?”

If one of your five covered devices is replaced or decommissioned during the licence period, you can deactivate the licence on the old device and activate it on the replacement — at no additional cost — through the My Kaspersky portal. Your 5-device coverage remains fully flexible throughout the licence term.

❓ “I already use a free antivirus — why should I pay for Kaspersky Standard?”

Free antivirus solutions come with fundamental limitations that matter enormously in a sophisticated threat landscape: no dedicated anti-ransomware protection, no real-time cloud threat intelligence, no advanced phishing detection, and often ad-supported interfaces that create their own security and privacy concerns. Kaspersky Standard’s paid tier delivers the complete protection stack — anti-ransomware with rollback, cloud-assisted threat detection, network attack blocking, and advanced anti-phishing — that free products simply do not offer at the same level. When the alternative is a ransomware attack that encrypts five years of family photos or a phishing attack that empties your bank account, the annual cost of Kaspersky Standard is not an expense. It is an investment with a guaranteed return.

The Kaspersky Legacy — 30 Years of Cybersecurity Leadership

Founded in 1997 by world-renowned cybersecurity researcher Eugene Kaspersky, the company has grown from a pioneering research operation into a global cybersecurity organisation employing over 4,000 specialists across threat research laboratories in 32 countries. Kaspersky’s researchers have been responsible for uncovering some of the most sophisticated and consequential cyberattacks in history — including Stuxnet, Flame, the Equation Group, and numerous state-sponsored Advanced Persistent Threat (APT) campaigns — demonstrating a depth of threat intelligence expertise that no pure consumer antivirus company can match.

That same intelligence infrastructure — the analysts, the global sensor network, the cloud threat database fed by 85 million users worldwide — is the foundation of every Kaspersky Standard licence. When you activate Kaspersky Standard on your five devices, you are not just installing software. You are connecting every one of those devices to the most comprehensive consumer threat intelligence network in the industry.

Protect All Five — Add Kaspersky Standard KL1041UCAFS to Your Cart Today

The uncomfortable reality of modern cybersecurity is that the question is no longer if your devices will be targeted — it is when, and whether your protection will be ready when it happens. Ransomware doesn’t select victims based on how careful they are online. Phishing attacks don’t skip households because they seem security-conscious. Malware doesn’t bypass devices because their owners are tech-savvy.

The only variable you can control is the quality of your protection — and the comprehensiveness of the devices it covers.

The Kaspersky Standard 5-Device 1-Year Antivirus (KL1041UCAFS) gives you the confidence that comes from knowing every device your household or team depends on is protected by a platform that has spent thirty years earning — and retaining — the trust of hundreds of millions of users worldwide.

Five devices. One decision. A full year of award-winning protection. Make it today.
