The extension is a companion, not a standalone antivirus
Kaspersky Protection works with a compatible Kaspersky application or plan. Install the extension from the official store flow, but do not treat the browser add-on as a replacement for the desktop or mobile protection product.
Where to download the Kaspersky Chrome extension safely
The safest Kaspersky Chrome extension download path starts on Kaspersky's official browser-extension support page and continues to the Chrome Web Store. The store is the place to add the extension; this directory only explains the route and checks what to verify before installation.
The Chrome Web Store listing checked for this guide identified Kaspersky Protection version 2.14.56.9, updated February 25, 2026, with a listed size of about 279 KiB. Store metadata can change, so confirm the version, publisher and permissions on the live listing instead of treating this page as a permanent package record.
The extension is designed to work with a compatible Kaspersky desktop application. If the add-on installs but does not show protection, first check the Kaspersky application, account entitlement, browser profile and extension status before looking for an alternate download.
Do not use a CRX mirror, patched extension, preactivated browser add-on or download portal that hides the publisher. Browser extensions can read or change data on visited sites, so the source and permission screen matter as much as the button that starts the install.

Who should install Kaspersky Protection in Chrome?
Use the browser-extension route when you already have, or are intentionally setting up, a compatible Kaspersky product and want the browser protection features it exposes.
- Use the official Chrome Web Store listing reached from Kaspersky's support instructions.
- Check the Kaspersky desktop application and account before assuming the extension is fully active.
- Review the requested permission to read and change data on websites you visit before selecting Add extension.
- Keep Chrome and the Kaspersky application updated so the companion connection can work normally.
- Use the Password Manager guide when your actual intent is a password-management browser add-on rather than web protection.
Install the extension and verify the first connection
Open the official Kaspersky support instructions, follow the Chrome Web Store link, verify the listing name and publisher, and select Add to Chrome. The screenshots on this page show the official installation flow; they are explanatory first-party material, not a substitute for the live store page.
Read the permission dialog before selecting Add extension. After installation, look for the Kaspersky Protection icon and open Chrome's extension manager to confirm that the extension is enabled in the intended profile.
Open the Kaspersky desktop application and finish any sign-in, activation or application update it requests. If a protection status remains unavailable, record the browser version, Kaspersky product and visible error before contacting Kaspersky Support.
Current consumer products normally use a Kaspersky account for subscription and device management. The download itself does not include a paid license. A trial, purchase or eligible activation code determines what becomes active after installation. Do not create multiple accounts to work around entitlement or region checks, because that makes renewals and device management harder.
Features described on marketing pages can depend on platform and country. Treat plan labels as a product-selection framework, then read the official local comparison before purchasing or migrating. If your account already displays a product and available devices, that account view is more useful than a generic search-result headline.
How to download and install from the official source
Use this workflow for a current subscription, an older Kaspersky product or a standalone utility. It keeps the publisher and entitlement clear and reduces the risk of a repackaged installer. Screens differ by country and product, but the source and account checks remain the same.
Confirm the product
Check the product name in My Kaspersky, your order email, license certificate or existing application. If the name is Anti-Virus, Internet Security or Total Security, read the migration notice before selecting a current plan.
Open the source page
Use the official-source button on this page. After the 15-second handoff, verify that the destination is a Kaspersky-owned domain or an official app store reached through Kaspersky.
Review local requirements
Confirm the operating system, account requirements, subscription terms and regional availability shown on the destination page. Do not rely on a file name or version number copied by an unrelated download portal.
Install and activate
Run the installer provided by the official source, approve the operating-system prompt and sign in with the legitimate account that owns the subscription. Restart only when the installer or support documentation requests it.
Before replacing an existing Kaspersky installation, note the account email and activation status. A current installer may upgrade the application in place, but preserving your account details is more important than preserving an old setup file.
After installation, run the built-in update process and review the protection status inside the application. Do not install a second real-time antivirus simply to compare detection results; use an official on-demand utility when you need a separate scan.
Chrome compatibility, permissions and account requirements
The Chrome Web Store controls the browser-side installation. Confirm that the listing name is Kaspersky Protection, the publisher is Kaspersky, and the browser is the Chrome profile where you want the extension enabled.
The permission prompt can mention reading and changing data on websites you visit, managing extensions and communicating with cooperating native applications. Read those permissions in context; they explain why the add-on can provide browser protection and connect to the Kaspersky application.
If the extension appears in Chrome but reports that protection is unavailable, open the Kaspersky application, sign in to the eligible account, update both products and restart Chrome. Do not solve a connection problem by installing a second copy from an unverified source.
Download and installation troubleshooting
Most download problems are caused by product entitlement, regional routing, an older installation or an unsupported device rather than a damaged link. Work through the checks below before searching for an unofficial offline installer.
| Problem | What to check |
|---|---|
| The source page shows a different product | Check your country selector and account entitlement. Older licenses may be mapped to Standard, Plus or Premium, and some dedicated product URLs redirect to a regional download center. |
| The installer rejects the activation code | Confirm the code belongs to the same product family, country and account. Do not publish the code in a forum. Use My Kaspersky or official support to verify migration eligibility. |
| Installation stops or asks to remove software | Save your work, identify the conflicting security product and follow the official removal instructions. Do not use a random registry cleaner or password-removal utility. |
| The app is missing from a mobile store | Availability can differ by store region and device. Start from the official Kaspersky product page and use the store destination offered there instead of downloading an APK from a mirror. |
| You need an offline or managed installer | Consumer and business deployment packages are different. Administrators should use Security Center or the official business portal; home users should follow the consumer account and download flow. |
Our official-source and version policy
Kaspersky Download Wiki is an independent navigation site. We do not claim to be Kaspersky or operate its download infrastructure. Each page identifies the current product, explains legacy naming and provides a transparent handoff to a Kaspersky-owned source. External download actions are marked as official-source handoffs and use nofollow because this site hosts no installers.
We record the date on which a destination responded, but a successful source page does not prove that one universal installer version is current worldwide. Kaspersky can vary releases, file sizes, features and store availability by platform, account and country. For that reason, this site does not invent a version number, checksum or file size. The destination page and signed installer metadata are the final references at installation time.
Cracks, leaked keys and preactivated builds are excluded
A modified security installer can disable updates, change trusted components or hide additional software. This site does not host or link to Kaspersky cracks, key generators, leaked activation codes, password bypass tools or preactivated packages. Use a legitimate subscription, an eligible migrated license, an official trial or a free utility designed for the specific job.

How do I install Kaspersky Protection in Chrome?
Open the official support route, go to the Chrome Web Store, verify the name and publisher, select Add to Chrome, review the permissions, select Add extension, and then confirm the icon and enabled state in Chrome's extension manager.
Why does Kaspersky Chrome extension request website permissions?
Browser protection features need to inspect or interact with pages and communicate with the compatible Kaspersky application. Read the live permission prompt and install only from the official store listing you intended to use.
Why is Kaspersky Protection installed but not working?
Check that the extension is enabled in the correct Chrome profile, the Kaspersky application is installed and signed in, the account includes the feature, and both products are updated. Restart Chrome before contacting official support.
Can I download a Kaspersky Chrome extension CRX file offline?
No stable offline CRX file was verified for this guide. Use the official Kaspersky support and Chrome Web Store flow; avoid patched, preactivated or mirror-hosted extension files.
Does this website host a Kaspersky installer?
No. Kaspersky Download Wiki hosts guides and source records, not executable installers, APK files, ISO images or deployment packages. The download action opens a Kaspersky-owned product, download or support page after a visible countdown.
Can I use the same download in every country?
Not necessarily. Products, stores, subscriptions and individual features can differ by market. Confirm the country and product shown on the official destination page. This directory does not route around regional restrictions or promise that a product is available where Kaspersky does not offer it.
How do I verify that the file came from Kaspersky?
Start from a Kaspersky-owned source, avoid download managers and inspect the operating system's publisher or signature information before allowing installation. If the publisher is unexpected or the file arrived inside an unrelated archive, cancel the installation and return to the official source.
