# Which antivirus is best for a Windows laptop that needs solid real-time protection without slowing the machine down to a crawl?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">If you want a Windows laptop antivirus that gives real-time protection but doesn't turn the machine into a slideshow, that push and pull between protection and performance is exactly where most people get stuck. I pulled the picks G2 reviewers most consistently praise on both counts, drawn from the <a class="a a--md" elv="true" href="https://www.g2.com/categories/antivirus">Antivirus</a> category, with each product's G2 rating alongside.</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/sophos-endpoint/reviews"><strong>Sophos Endpoint</strong></a> (4.7 stars, 834 reviews) gets strong marks for set-and-forget protection that runs quietly in the background, with deep-learning detection catching threats signatures miss. One honest caveat worth knowing: several reviewers note the agent can spike CPU on older or lower-spec laptops during a full scan, so it leans best on a reasonably modern machine.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/eset-protect/reviews"><strong>ESET PROTECT</strong></a> (4.6 stars, 1,002 reviews) comes up again and again for being light on resources, with reviewers saying machines run just as fast as before with no noticeable slowdown even during scans.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/threatdown/reviews"><strong>ThreatDown</strong></a> (4.6 stars, 1,088 reviews) runs a lightweight agent that reviewers say causes minimal interruption and no real performance hit while still stopping malware and ransomware. If you want strong detection that stays out of your way, it's a common pick.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/webroot-business-endpoint-protection/reviews"><strong>Webroot Business Endpoint Protection</strong></a> (4.5 stars, 532 reviews) is about as light as it gets, running quietly with fast scans and real-time protection. Reviewers repeatedly call it unobtrusive and note it doesn't drag devices down, though a few feel its detection tech is showing its age.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Which way are you leaning, the absolute lightest footprint or the strongest detection? And has anyone tested these on a mid-range laptop specifically?</p>

On the mid-range laptop question: reviews rarely name hardware, which is exactly why I&#39;d trust the free-trial route here. Install the two finalists for a week each and watch boot time and fan noise, since the footprint complaints in reviews cluster around real-time scans during startup. Detection differences between the big names are smaller than the performance differences reviewers describe.
