Best Free Antivirus for Home Use (2025 Edition)

🕒 Updated October 2025 — Sophos Home Free is no longer available to new users, but there are still great free antivirus options.

If you’re looking for a trusted, no-cost antivirus solution for your home PC or Mac, here’s the 2025 reality: most vendors now offer free trials instead of fully free versions. However, a few excellent choices remain that deliver real-time protection without requiring a paid subscription.

⚙️ Top Recommended Free Antivirus Tools (2025)

  • Microsoft Defender (Windows 10/11) — Built into Windows and now one of the best free antivirus options available. It includes real-time protection, ransomware defense, and smart cloud-based threat detection. No registration or ads.
  • Avast One Essentials — Free tier with core antivirus, Wi-Fi inspector, and password protection. Lightweight and easy to use.
  • Bitdefender Antivirus Free — Simple, minimal interface with strong malware detection. Works quietly in the background and auto-updates daily.
  • Kaspersky Free (Standard) — Offers solid real-time protection, web filtering, and phishing prevention. Independent lab tests rank it highly for detection accuracy.

🔒 About Sophos Home

Sophos previously offered a permanent free version of Sophos Home that supported up to 10 devices. As of late 2021, new sign-ups now receive a 30-day free trial of Sophos Home Premium. After that trial, continued use requires a paid subscription (about $59.99 per year for 10 devices).

If you created your Sophos Home Free account before November 11 2021, you can continue using it, protecting up to three devices. Everyone else now gets the 30-day trial. You can still download the installer at Sophos Home, but note that it will activate the trial version.

🧠 My Personal Experience

I used the paid Sophos Endpoint suite at work for years and found it extremely reliable. For home use, I now rely on Microsoft Defender since it’s integrated into Windows and managed easily across multiple systems. Defender’s performance and detection rates have improved significantly since its early days.

🧹 Recommended Malware Cleaners for Infected PCs

If you suspect an active infection or slow performance even with antivirus installed, two trusted free cleanup tools can help:

  • Malwarebytes Free Edition — Excellent for on-demand scans and removing stubborn adware, spyware, and rogue programs that traditional antivirus might miss. It doesn’t run in real time, so it’s ideal as a secondary cleanup tool.
  • SuperAntiSpyware Free Edition — Great companion scanner focused on spyware, tracking cookies, and hard-to-remove system infections. It’s lightweight and easy to run on-demand.

I typically use both tools when cleaning infected computers. Run full scans from each, remove any detected items, and then reboot. After cleanup, keep a modern antivirus active — whether that’s Microsoft Defender, Bitdefender Free, or another reliable suite — for real-time protection going forward.

💡 Tip: Always download Malwarebytes and SuperAntiSpyware directly from their official websites to avoid fake or bundled installers.

💡 Final Thoughts

For most home users in 2025, Microsoft Defender provides more than enough protection with no ads or upsells. If you want extra layers (VPN, password manager, privacy tools), consider a reputable premium suite like Bitdefender Total Security.

✅ Updated October 2025 — Free antivirus options verified and links checked. Always download from official vendor sites.

EXTERNAL domain warning for zimbra

With the phishing attempts that consonantly target users your company can get exposed to a possible infiltration because a user thought a representative of the company sent them an email asking to change the password or to cleanup a full inbox, etc. In the email they will have a link and a login page that is used to collect the users login name and password. Many companies are starting to implement some kind of indication to the user that the email originated outside the company. Some will add a tag to the subject like [EXTERNAL] if the mail system has capabilities for using transport rules, spamassasin header, postfix header_checks. Other phishing attempts would use CEO names in the name field with a different return email address. The way users fall for this is they do not look at the originating email address. It also does not help that most mail clients will only show display name when provided instead of the email. Currently zimbra does not have a way to creat...

Remove EXTERNAL from subject on exim for email leaving your domain

In an earlier post I mentioned how to tag/add EXTERNAL to the subject header on exim.  I made the changes on our Sophos UTM which may require re-applying the configuration files after Sophos UTM update. I ended up adding and elif block to act on outgoing emails in the exim.system_filter file this is the block I added.  Change your domain as appropriate and add additional lines if you need to. elif  $header_from: contains "@yourdomain.com>"  and $header_to: does not contain "@yourdomain.com>"  and $header_subject: contains "[EXTERNAL]" then  headers add "Old-Subject: $h_subject:"  headers remove "Subject"  headers add "Subject: ${sg{$h_old-subject:}{[[]EXTERNAL[]]}{}}"  headers remove "Old-Subject" endif This is the full exim.system_filter file To have the $h_from or $header_from act on the domain part and not the display name part if someone was trying to spoof the from name I added the > at the ...

zimbra change domain ham spam galsync and virus accounts

Do the domain that was created by default is not the domain that you intended.  Or when you setup zimbra you were not paying attention and server name got added in front of the domain ie mail.domain.com instead of just domain.com. Now you need to setup the ham, spam, galsync, and virus-quarantine accounts to your new domain. Lets start with ham and spam. From zimbra webadmin find the spam and ham accounts under manage and then search individually for ham and spam.  They will have random characters after the name.  We will need the full name of both accounts.  Right click to edit the account and under account name change the domain to your newly created domain and save.  Do this for both accounts.  Also get the names of both accounts.  You can copy and paste them to use in the following command line. As zimbra user on the mail server run these commands. You can also check the current spam accounts with zmprov gcf zimbraSpamIsSpamAccount zimb...
