How to Download Avast Free Antivirus SafelyAvast Free Antivirus is a popular choice for users who want basic protection without paying. Downloading any antivirus safely is important to avoid fake installers, bundled unwanted software, or malware posing as legitimate programs. This guide walks you through each step: verifying authenticity, choosing the right edition, preparing your PC, performing a secure download and installation, configuring the product, and keeping it updated and clean.
Why safety matters
Downloading software from untrusted sources can result in:
- Malware or trojans disguised as antivirus installers.
- Browser hijackers, adware, or unwanted toolbars bundled with installers.
- Outdated or tampered installers with security vulnerabilities.
Always download Avast Free Antivirus only from the official Avast website or other trusted distribution channels (e.g., Microsoft Store when available) to minimize risk.
Step 1 — Check system requirements
Before downloading, confirm your device meets the minimum requirements:
- Supported OS: Windows ⁄11 (32-bit or 64-bit). macOS and Android have their own Avast products.
- At least 2 GB RAM and 2 GB free disk space recommended.
- A stable internet connection for download and activation.
If your computer runs an older OS (Windows ⁄8), consider upgrading the OS first or using an Avast version specifically marked for legacy systems, understanding that older systems may be less secure.
Step 2 — Prepare your system
- Back up important files (cloud or external drive) in case you need to revert changes.
- Uninstall conflicting security software. Running multiple real-time antivirus programs can cause conflicts and performance issues. Use the other product’s official uninstaller or Windows “Apps & features.”
- Update Windows and your browser to their latest versions to reduce compatibility issues.
Step 3 — Use a secure device and network
- Download from a device you trust (avoid public/shared computers).
- Use a secure network — avoid public Wi‑Fi for the download/activation step. If you must use public Wi‑Fi, use a reliable VPN.
Step 4 — Navigate to the official download source
- Open your browser and go to Avast’s official website. Typing the URL manually (https://www.avast.com) reduces the risk of typosquatting.
- On the Avast site, locate the “Free Antivirus” product page. Confirm the site uses HTTPS and that the domain is correct.
- Alternatively, use the Microsoft Store (Windows) for added assurance; apps there go through Microsoft’s vetting process.
Step 5 — Verify authenticity before downloading
- Check URL carefully for misspellings or extra characters (e.g., avast-security.com is not Avast).
- Look for official branding and up-to-date privacy/policy links.
- If you arrived via search results, prefer the official site link; avoid third-party download sites (these often bundle extra software).
Step 6 — Download the installer
- Click the official “Free Download” button. The installer will typically be a small stub that downloads required components during installation.
- Save the file to a known location (Downloads folder).
- Optional: Check the file’s digital signature (Windows Explorer → Right-click file → Properties → Digital Signatures) to ensure it’s signed by “AVAST Software s.r.o.” or similar trusted publisher.
Step 7 — Scan the installer (optional but recommended)
- Right-click the downloaded file and scan with Windows Security (built-in) or another trusted on-demand scanner to ensure it’s clean.
- If you have another offline scanner (USB-resident), use it before running the installer.
Step 8 — Install carefully
- Run the installer as an administrator (right-click → Run as administrator).
- During installation, choose “Custom” or “Advanced” install if available to avoid opt-out bundled apps or browser extensions you don’t want (e.g., toolbars, browser add-ons, or separate Avast products).
- Read each step carefully and deselect offers for extra software (VPN trials, cleaning tools) if you don’t want them.
- Allow Avast to enable real-time protection and automatic updates — these are central to antivirus effectiveness.
Step 9 — Post-install checks and initial configuration
- After installation, allow Avast to perform its first full update — definitions and program updates.
- Run a full system scan immediately to establish a clean baseline.
- Open settings and configure:
- Automatic updates: enabled.
- Scheduled scans: set a convenient time (e.g., weekly).
- Notifications: adjust to reduce interruptions but keep security alerts on.
- Ransomware Shield and Real Site (if available in free tier): enable if offered.
- Create an account only if you want centralized device management; it’s optional for basic protection.
Step 10 — Keep Avast and your system secure
- Do not download software from unofficial sources. When installing new programs, prefer official vendor pages.
- Keep Avast up to date — enable automatic updates.
- Apply Windows updates and keep browsers/extensions updated.
- Periodically run full scans and review quarantined items.
- Remove unused browser extensions and apps to reduce attack surface.
Troubleshooting common issues
- Installer fails or hangs: Re-download from the official site; restart PC; temporarily disable other security software; run the installer as administrator.
- Conflicts with existing antivirus: Fully uninstall the other antivirus and reboot before installing Avast.
- False positives: Quarantine items can be restored via Avast’s interface if you believe they’re legitimate; submit samples to Avast for analysis.
Privacy and bundled offers
Avast may present optional offers (VPN trials, performance tools). Read prompts carefully. The free antivirus provides core protection; extras are optional and may require additional permissions or account creation. If privacy is a top concern, avoid opting into extra cloud features that upload sample files unless you understand the implications.
Quick checklist (one-line reminders)
- Download only from https://www.avast.com or Microsoft Store.
- Back up important files first.
- Uninstall other real-time antivirus products.
- Choose custom install to avoid bundled extras.
- Run initial full scan and enable automatic updates.
