BitDefender Free but I haven't found a single one ever, in fact I haven't found a single Windows virus in any of my files I've downloaded either >_>

Same here...

Even though I'm frequenting the back alleys of the net quite often, I've never caught crap. ;)

Use Avira for Mac, it's by far better than the rest. =D

Interesting. I've used Avira for years on the PC, but didn't realize they had a free version for OS X as well. I've been using/recommending Sophos Free for OS X for almost two years now. Does Avira have the annoying pop ups like the Windows version?

Hello,

There are many companies which make anti-malware software for Mac OS X, including Avira (in beta now, I believe), ESET, Intego, McAfee, Sophos, Symantec and Trend.

Regards,

Avast also have a free version for OSX (in beta, but it looks good):

I personally don't use anything and I honestly can't remember the last time I've had a virus on any platform - I think the last one was the RPC exploit on windows which would make you constantly reboot (Blaster worm). And that wasn't to do with anything I downloaded was just a exploit in Windows

I have never really paid attention to the RAM it uses. Does it use a lot? This is what Activity Monitor tells me.

I have an iMac and I recently installed Sophos because of the Flash virus deal. I scanned the computer and all is good but to be honest, I don't have it running in the background. I use my Mac for business stuff only. I don't visit porn sites, poker sites or warez sites or do anything stupid with it so I'm not really too worried about catching a virus on it. Besides, Apple has a reputation to keep and their ego is way up there. They will never allow a virus or viruses to attack and destroy OSX so you can be sure they will patch whatever security holes come up within hours to make OSX secure again.

How can you tell which actually work and which ones do nothing at all? There is not a lot out there to test with

So at the moment they should have a 100% detection rate. Hell, they should be able to use heuristics to detect any software that makes use of known exploits. But that's my concern with the Mac at the moment - it's getting actively targetted with malware, but there's no idea which software properly protects. At least with Windows you know that MSE is free and relatively non-intrusive, so it isn't a case where the cure is worse than the disease, and it does actually catch malware, or alternatively if you buy WebRoot Secure Anywhere and install it on a clean system you're close to 100% guaranteed you won't get any new infections. The devil you know is better than the devil you don't.

Right now I would just pick a free Mac AV program that uses the least resources possible, run FireFox with NoScript and Web of Trust and make damn sure I know what I'm downloading.

I believe that having an "antivirus" program on your Mac would be like giving it a virus, using system resources that would otherwise be free. There's no need for one and if you can wait, there will be one built into Mountain Lion. I've haven't used an antivirus program since I started using Vista, there's just no need. Microsoft does a good job looking after its OS and I'm sure Apple will do so too. The amount of crap and popups that result in installing a majority of antivirus programs is just not worth it.

Your faith is completely misplaced. Apple won't take care of security until they repeatedly get hit with malware and it causes them seriously bad publicity.

Gatekeeper is not a malware detector or antivirus system.

    • Quantum Error Correction Validated in Nature: Microsoft and Quantinuum Log 800-Fold Improvement Two years after the original press-release announcement, independently peer-reviewed results published in Nature on June 10, 2026, have confirmed that Microsoft and Quantinuum achieved an 800-fold reduction in quantum error rates on real trapped-ion hardware — the largest gap between physical and logical error rates ever independently validated.    What Quantum Error Correction Actually Does — and Why Breaking Even Is Hard https://www.techtimes.com/articles/318329/20260613/quantum-error-correction-validated-nature-microsoft-quantinuum-log-800-fold-improvement.htm   Quantum Computing Wiring Bottleneck Cracked by HKU Silicon Carbide Chip at Qubit Temperature Engineers at the University of Hong Kong have built the first cryogenic control chip that operates at the same temperature as superconducting qubits — 10 millikelvin, or just one-hundredth of a degree above absolute zero — without generating the heat that has forced every competing approach to park its electronics hundreds of meters of cable away. https://www.techtimes.com/articles/318325/20260613/quantum-computing-wiring-bottleneck-cracked-hku-silicon-carbide-chip-qubit-temperature.htm  
    • RevPDF 4.5.0 by Razvan Serea RevPDF is a free, fully offline PDF editor for Windows, macOS, and Linux that lets you edit text and images directly inside PDF files — no internet connection, no account, and no cloud uploads required. Unlike bloated alternatives that demand subscriptions and constant connectivity, RevPDF fits in under 60MB on desktop while delivering a complete editing toolkit: annotate, redact, sign, compress, split, merge, convert, and reorganize pages, all processed locally on your device. Smart font matching ensures edited text blends seamlessly with the original, and multi-language support includes RTL scripts such as Arabic and Hebrew. Where most PDF editors force you to choose between features and simplicity, RevPDF manages both. You can build interactive forms from scratch with text fields, checkboxes, and dropdowns, permanently redact sensitive data before sharing, draw freehand on contracts and diagrams, and add custom watermarks — all without a single file leaving your machine. Edit Text and Images Directly Inside PDFs RevPDF supports true inline PDF editing — not just annotation layers on top of a document, but actual modification of existing text and images within the file. A smart font-matching engine identifies the font used in the original document and applies it automatically when you make edits, so changes blend naturally with the surrounding content. You can reposition elements, resize images, and update text across single pages or entire documents. RevPDF 4.5.0 release notes: This is one of the biggest updates to RevPDF yet. A lot of things people have been asking for are finally here. New Features Auto Redaction Permanently redact sensitive text and areas from your PDFs before sharing. Clean, irreversible, and fully offline. Comments, Links & Bookmarks Add comments for review, insert clickable links, and create bookmarks to jump around long documents without scrolling forever. Find & Replace Search across the whole document and replace text in one go. Long overdue. Split Pages Vertically or Horizontally Split any page down the middle, vertically or horizontally. Perfect for scanned books or double-page spreads. New Drawing Tools More tools for freehand drawing and markup, better for annotations, sketches, and detailed notes. Continuous Scrolling in Editor The editor now scrolls continuously through pages instead of jumping between them. Working through long documents is a lot smoother now. PDF Metadata Editor View and edit the metadata stored inside your PDFs, including title, author, subject, and keywords. Better Font Matching Text edits now blend in more naturally by doing a better job of matching the original font. Tabbed PDF Viewer Open multiple PDFs at once in tabs and switch between them without going back to the home screen. Add Links Insert hyperlinks anywhere in your PDF, to external URLs or to other pages within the document. Share & Print Shortcuts Share or print directly from the editing screen, home screen, and viewer. No extra steps. Minor Updates Paste images directly from clipboard into your PDF New image editing tools for more control over images inside documents Bug Fixes Fixed file saving issues on Windows and Linux Everything still works fully offline. No login, no cloud, no account. Your files stay on your device.

    • Interesting. I'm not using a VPN with my phone. I tried though my home internet (Rogers) and my cellular internet (Telus) and both trigger the dialog above.

    • Microsoft fired the team and replaced them with AI and this is what you get.
