Avast vs Bitdefender Free 2026: Windows Protection
Compare Avast and Bitdefender free antivirus for Windows, including real-time protection, paid upgrades and business-use limits.

Bitdefender Antivirus Free for Windows offers real-time protection and scheduled scans without a trial period. Avast also documents scheduled Smart Scans for Avast Free Antivirus, so check which app version you install before deciding on that feature.
Avast Free Antivirus fits a personal Windows PC, and Premium Security's published 10-device offer is $69.48 the first year and $99.99 per year at renewal. Skip both free downloads on a company laptop until the license allows it. There is no detection winner on this page, because we did not run a malware test.
The Avast free-product page, Avast business guidance, Avast US offers and Bitdefender's free Windows guidance were checked on October 28, 2026. Those pages describe the features each vendor claims, who may use the product, and what the Avast promotion costs, and they are not a lab score.

|---|---|---|
| Entry price | Free consumer product | Free Windows product |
| Malware protection | Avast describes real-time detection and blocking | Bitdefender describes real-time malware protection |

A free download removes the purchase price and leaves licensing, updates, and alerts with you. Avast suits a home PC that may later buy Premium Security or Ultimate. Bitdefender suits a home PC only after you confirm the license and the device requirements.
What the free products promise
Avast says its free antivirus detects and blocks malware in real time and scans a Windows PC for malware. That suits someone protecting their own Windows PC who will follow the current installer rather than an old screenshot. The page now presents the free antivirus in the Avast One app, so the controls you get depend on the operating system and version you install. Avast support also describes scheduled Smart Scans for Avast Free Antivirus; confirm the controls for the version you install.
Bitdefender says its free Windows product offers real-time malware protection without a trial period. Its free-product user guide describes customizable scheduled scanning. That suits someone who wants scans at a chosen time and a free tier that is not described as a trial. Its documentation notes that the newer free product replaced an older edition, so a guide for the retired name can point at menus you will not find. Check the installed product name against the current support page before you follow that guide.
Those statements are vendor descriptions rather than comparable laboratory results, and a feature label cannot tell you how either product performs against a particular threat or what impact it has on an older computer. An organization choosing antivirus should define the threat it cares about and judge independently obtained evidence for the version and settings it will deploy.
Free-tier verdict: both vendors describe real-time malware protection, Bitdefender's free-product guide describes customizable scheduled scans, and Avast support describes scheduled Smart Scans for Avast Free Antivirus. Choose after you check compatibility, licensing, and the workflow you will keep.
What an Avast upgrade costs
When checked, Avast's US offers page advertised Premium Security at $69.48 for the first year for 10 devices, with a displayed renewal price of $99.99 per year. It also showed Ultimate at the same introductory total with a higher stated renewal. These are promotional consumer offers, not a guarantee that your checkout will display the same prices or terms. Budget the lower first year and the higher renewal if you want those paid features, and ignore the banner if the free tier already covers the personal use Avast describes.
For a simple two-year illustration, one introductory year of the listed Premium offer plus one year at the displayed renewal totals $169.47 before applicable tax and assuming the rate remains unchanged. The first year is $30.51 below that displayed renewal, which is the discount you give up when the promotion ends. That arithmetic matters only if you need the paid features and the same offer is still at checkout.
The offer is not a business deployment price, because Avast's business guidance distinguishes consumer products from its business solutions. A company that multiplies the consumer promotion across employees is pricing the wrong catalog, and should request the commercial license, the number of protected endpoints, and the management capabilities instead.
Bitdefender has free and paid products, and the paid price has to be the vendor's current figure for the device count and term you want. This page does not carry that checkout price, so a paid comparison against the Avast promotion has to wait on the vendor. The free antivirus guide covers other no-cost options, while Bitdefender vs Norton compares paid products using dated prices.
Cost verdict: both free tiers remove the purchase price for their stated use. On the Avast offer, compare the first term and the renewal for the device count you will protect, and do not treat a paid Bitdefender plan as the pair until you have its current checkout price and equivalent coverage.
Can a business use the free download?
Avast states that its free consumer antivirus, Avast One and Premium Security are intended for private, personal and noncommercial use. Its business product guidance recommends business products for commercial organizations. The free download suits a personal machine, while a company laptop is outside that use, and installing it there leaves you without the product Avast tells businesses to buy.
For Bitdefender, read the current license for the exact free product and location, or ask the vendor whether the organizational use you intend is permitted. This article does not assume a business license from the word free, and a permission inferred from an older product name does not carry to the edition that replaced it. Until the vendor confirms the use, keep the free Windows product off machines the organization owns.
A security lead may still need centrally managed policies, visible device status, alert routing, access controls, and a documented response process. Those functions may require a business endpoint product or additional tools, and a consumer application on an individual device does not replace them. The endpoint protection guide and the business antivirus guide cover that category.
Business verdict: confirm Bitdefender's license and each vendor's management features before either free product is deployed across an organization. Avast has already separated those consumer names from its business products.
Scanning, alerts and updates
Real-time protection checks activity as it occurs, while a scheduled or manual scan checks selected files at a chosen time. Neither task reviews the alert or decides whether another account needs attention. Bitdefender's free-product guide names a customizable schedule, and Avast documents scheduling for Avast Free Antivirus. Check the installed version and scan settings when nobody opens the app unless something looks wrong.
Before installing, check each vendor's current system requirements and update process. Security software that cannot update, or that conflicts with another security product, may leave a false sense of coverage. Follow the installation and removal instructions, then confirm the protection you wanted is on.
Keep operating-system updates, a supported browser, software from trusted sources, and backups you can restore, and name someone to own alerts in a business. The phishing prevention guide covers a path antivirus may not stop. If you suspect malware, follow the incident procedure rather than treating a scan as the investigation, and use the ransomware response playbook when ransomware is the case. Test a restore before you need it, because a backup that cannot be restored is not a recovery plan.
Operations verdict: pick the product whose workflow you will maintain. A scan list helps little if nobody owns updates, alerts, and recovery.
Choosing a product
For a personal Windows PC, read each vendor's current free-product and support pages and confirm operating-system support, updates, and how alerts appear. If you need a paid Avast feature, compare the full term for your device count rather than the introductory banner. If you need a paid Bitdefender feature, get the vendor's current price and match the coverage before you choose.
Security software may inspect files, send threat telemetry, or connect to vendor services, so read the current privacy notice before you install and do not turn protective functions off without knowing what that removes. A household and an employer do not share the same consent question. On a company-owned device that stores customer or regulated information, the person responsible for security and procurement should decide.
Privacy verdict: neither feature list says what the installation sends, so compare the current notice and write the decision down when the organization owns the device.
A company quote should name the device count, the reporting, and the support. The device list should say who owns each machine, which version is installed, where alerts go, and how you replace a laptop that is lost or compromised.

How we compared
We read the linked vendor pages on October 28, 2026 and calculated the two-year illustration from Avast's stated US promotional and renewal figures. We did not install, test or audit either product. Vendor features, license conditions and offers can change; verify them before installing or purchasing.
FAQ
Are Avast and Bitdefender free on Windows?
Each vendor describes a free Windows antivirus product, so the download itself has no purchase price. Match it to your operating system and read the license first, because a personal PC and a company computer are different decisions.
Does free antivirus include real-time protection?
Both cited vendors describe real-time malware protection in their free Windows offerings. Bitdefender describes customizable scheduled scans and no trial period; Avast Free Antivirus support also describes scheduled Smart Scans. The Avast download page presents Avast One, so verify the installed version. Neither claim is a detection test.
Can a business use Avast Free Antivirus?
Avast's business guidance says its named consumer free product is for personal, noncommercial use, and the same limit covers Avast One and Premium Security. A paid consumer plan does not make that a commercial license, so a company should buy the business product rather than install the free download on staff laptops.
How much is Avast Premium Security?
The US offer checked on October 28 listed $69.48 for the first year for 10 devices and $99.99 per year at renewal. Ultimate was advertised at that same introductory total with a higher stated renewal. Promotions and tax can change, and the renewal is what you budget if you keep the plan.
Is Bitdefender Free licensed for my business?
Check the current license, or ask the vendor, before any organizational deployment. A free download does not establish commercial usage rights, so keep it off company machines until that permission is confirmed for the edition you will install.
Does an antivirus replace backups and account security?
No, antivirus is one part of a security plan, and updates, tested backups, account protection, and a response process cover risks a scan does not. A clean scan is not the investigation, and a backup you have never restored is not a recovery plan.
