Free Business-Grade Antivirus For Your PC


Sophos AntivirusIf you use Windows 10 then you're probably relying on the built-in antivirus and security software called Windows Defender. But if you want something a little more powerful and feature-rich, then have a look at Sophos Home. Sophos is a well-known supplier of security software to companies around the world, but you may not be familiar with their name as they don't sell to individual users.

They do, though, have a home-use product which they actually give away for free. And because it's basically the same as the business product which they sell, it's pretty good.

Isn't [malware] "MALicious softWARE"? (software written with malice as the intent)

This is NOT a criticism of the editor who I thank for their work.

Going strictly from comments I feel this article should be pulled or at the very least the description altered to note that many features are really 30 day trial.

For this novice the description had me at "interesting, might install this" but after reading the comments, "no way this is freeware, more like trialware, no interest whatsoever".

The program not found by Windows Explorer was JS-Miner-C

Maybe because this is not malware. It is in fact a method by which user visits to websites can be monetized. Herein though lies the dilemma many Windows users will experience trying to identify antivirus flags as malicious or not. This situation of course is not new. There never has been and never will be any security software that can 'protect' Windows users so long as Windows remains the most used and therefore targeted operating system. The more correct definition is the security industry provides a range of software free and paid that 'assist' Windows users to stay malware free but with no guarantees, although reading the clever wording on vendor websites often suggests something more definite. This is why I switched to Linux years ago. MC - Site Manager.

Bullcrap. It meets every definition of malware. It installs software on a persons computer and runs it without the users knowledge or permission. If it looks like a duck and quacks like a duck, it's a duck.

Switching to Linux isn't the answer for everyone due to software needs that aren't available in Linux or thru the use of WINE, etc. Don't get me wrong tho. Linux is a wonderful OS and works just fine for some people. But just like Tablets and Smart Phones aren't appropriate for all computing needs, neither is Linux.

The best option for dealing with crap like these miners is the use of anti-miner browser add-ons/extensions.

Like many other words, the term "malware" has been adopted to cover a broader range of definitions than was originally intended, this being: "Computer programs designed to infiltrate and damage computers without the users consent". (BullGuard) "Software that is specifically designed to gain access or damage a computer without the knowledge of the owner". (Norton) "Computer software that is designed to damage the way a computer works". (Cambridge English Dictionary) Notice the use of the term "damage" as opposed to a lesser state of "annoyance" such as restricting CPU performance that can easily be rectified with no lasting "damage". MC - Site Manager

Again I say BullCrap. It's obvious you haven't been following this very closely as there are numerous LEGITIMATE cases of damaged hardware due to these miner infections. A client of mine had their smart phone get so hot it damaged the processor rendering it unusable. Now try to tell me these miners don't fit the definition of malwarr with a straight face.

This page relates to Windows PC's, not Android. I've yet to see a PC that has been permanently damaged due to the presence of crypto-currency mining scripts. MC - Site Manager.

It doesn't matter. They are still malware. And while a desktop shouldn't have any problem with them, notebooks are a different story. A lot of the older ones don't have robust enough cooling solutions to deal with the amount of heat generated by the miners and more than a few have been damaged to the point where their gpus have stopped working and/or their cpus needed to be replaced. That is real damage to most right minded people.

But it's obvious that you just want to skirt the issue.

So first you were talking about a global hardware issue then this became phones which are not relevant here and lastly we arrived at notebooks, specifically old notebooks. So in fact the potential for any damage relates to only a tiny percentage of user hardware. Even so, and just as you would with your car, once you observed it running hot you would naturally want to find out why and get it fixed. All the leading antivirus and independent security forums contain threads about crypto-currency miners including how to remove them and prevent future installation so there is ample opportunity for users of even obsolete hardware to resolve the issue before any permanent damage is done. Granted that for some novice users, actually identifying the problem could be an issue but resources such as Tom's Hardware and others would quickly identify the source. MC – Site Manager.

The average user isn't going to know what to do about this and would rightly expect their anti-malware product to take care of it ON IT'S OWN. You can try to justify it all you want, but it is MALWARE plain and simple. Just because you don't understand why change anything. I've been doing this since the mid 70's and know what Malware is and isn't, and this qualifies no matter how you try to state otherwise and everyone here knows it is.

I have been using Panda Free AV on several computers including friends and family PC's I have worked on for a few years now.
Very effective, feature rich and light on resources. I receive NO pop-ups or advertisements to upgrade. You just have to go to settings
and turn off "show Panda news"
Switched from Avast and have never looked back.
I am in no way affiliated with Panda, I just think it is a great alternative to Windows "security"

Thanks for your post, smoaky. After switching and trying different A/V protection for years, it's good to hear someone reviewing Panda. I'd used Panda for 3 years and when they switched to free cloud protection about 6 months before moving on. Avast is wearing my likeability thin with their ads and popups.

Most Avast popups in the free version can be disabled by uninstalling the components you don't use (vpn, safeprice, password, pc cleanup...).

I was just wondering if Sophos Business-Grade Antivirus for the home edition is actually business grade checked their website and found out this. In reality, it is not free but 30 day trial period after which
1. Advanced Real-time Protection = Expires after a free 30-day trial of Sophos Home Premium.
2.Advanced Ransomware Protection = Expires after a free 30-day trial of Sophos Home Premium.
3.Advanced Web Protection= Expires after a free 30-day trial of Sophos Home Premium.
4.Banking Protection = Expires after a free 30-day trial of Sophos Home Premium.
5.Privacy Protection= Expires after a free 30-day trial of Sophos Home Premium.
6. Advanced Malware Removal=Expires after a free 30-day trial of Sophos Home Premium.
If all these expires than very little remains.
I wish if someone enlightens's me why should I use Sophos home edition.
Comparing to 360 Total Security which all the above free without conditions plus multiple antivirus engines built in with a very light footprint.

Totally free, light on resources, extremely fast scan times and pre-configuration protection modes

Smooth running installer with no adware, pleasing UI and comes with many themes

Fast updates/fixes and excellent customer service with immediate replies

Great signatures with multiple engines and in-house cloud protection

Web protection addon, browsing locking, webcam, sandbox and USB protection modules

Online shopping protection, malicious URL protection, and network threat blocking

Includes Glasswire Firewall and Windows patch-up components

Great detection rates, with very high zero-day protection

The biggest problem with Sophos is it just deletes anything it THINKS is Malware and doesn't give you any options. I gave up on it a long time ago because of that as it flagged too many false positives and deleted legitimate files and programs.

Was ready to try until site compare. After 30 days trial a whole bunch of the advanced RT features quit unless pay up. Pass. Thanks tho since Win Defender & Malwarebytes suffice. Do wish I could safely defeat the auto launch screen each boot. Did google but haven't figured a way to keep active but have screen then fade out. So far just get all or nothing results as to that dashboard screen launch. Check more when have time.

Just wondering. Is it worth the 'hassle' to install a separate antivirus product when I have Defender that's a part of the OS?

Windows Defender did not detect a mining bot (or malware) and Avast Free did. My GPU was 100% busy even when PC was idle, games were stuttering when playing and fps dropped at random. Thanks to task manager I found out the culprit and Virustotal told me that was a mining malware. I read the AV detection list and guess what ? Windows Defender didn't recognize it. That was enough for a change. I'll try to find the malware name and post it here. I don't surf dangerous websites, maybe it was just something random, but better safe than sorry. The downside is ads, moreover I hate those that want to clean my windows registry (dangerous) or delete "useless" files.

Before deciding on any change of malware protection you first need to analyze what your exposure risk is by comparing your surfing and download habits with the product features available. Many of the Sophos features for example are disabled in the free version after the 30 day trial (included) expires whereas other free options such as AVG might be a better option. MC - Site Manager.

Hi Rob,

Any idea if it bombards you with multiple, daily pop-ups as other free AV's do? I don't run Windows, but I do get asked by others if I know of a good freebie.

Seems it has got decent ratings in online reviews...

I can assure you Sophos Home is the quietest free AV ever. I've been using Sophos Home now for over 12 months, never received any sort of popup, ad, or nag, Sophos Home just sits quietly in the background doing its job.

I am in no way associated with the software, just a satisfied user.

I submitted a very positive comment which was pulled. Presumably, it was assumed that I was either associated with Sophos or had some financial interest? Neither of these assumptions are correct. I'm just a satisfied user who appreciates software that 'sits quietly in the background doing its job'. I bought an annual subscription for 360 Security but deleted it after one month. I just couldn't 'shut it up'. Sophos was such a refreshing change. I've got access to all the features now because I participated in their beta program. I'll gladly pay the subscription when it's due.

What about memory footprint ? Disk activity ? I use Sophos Endpoint Security And Control at work (LAN, more than 1000 windows computers) and I'm not very satisfied but maybe it's only because of policies or settings.
