Best Midrange PC Antivirus Software

Midrange antivirus software for Windows combines the basic protections of inexpensive products with additional features that usually include parental controls and a two-way firewall. Some brands also toss in a password manager or a file shredder, but you may want to move up to the higher-priced, premium antivirus products for secure online storage or system optimization.

Among the eight products we recently reviewed, our Editor's Choice in this category is Kaspersky Internet Security, which combines excellent malware protection with a very light system load and a plethora of helpful extra features.

Right behind that is Bitdefender Internet Security, which offers even more tools but has malware protection that's just a hair shy of Kaspersky's.

Three other products — F-Secure Internet Security, Norton Security Deluxe and Trend Micro Internet Security — had malware protection comparable to Kaspersky's and Bitdefender's, but suffered from heavy system loads when scans were running, and sometimes even when they weren't.


How We Tested

Programs from all eight brands  were evaluated on an Asus X555LA laptop running fully patched 64-bit Windows 10 on an Intel Core i3 processor. The laptop had 6GB of RAM and 36GB of files on a 500GB hard drive. Each antivirus product was uninstalled before the next was loaded.

We evaluated each product's ease of installation and ease of use, enumerated its protective features (and how useful each feature might be), and took note of its navigation scheme and interface.  

To gauge how well a product detected malware, we used recent sets of evaluations on Windows 10 and Windows 7 from German independent lab AV-TEST, which regularly tests antivirus software against both previously seen, widespread malware and the more dangerous zero-day malware that can be detected mainly by behavioral analysis. We also used results from AV-Comparatives in Austria, which exposes antivirus software every month to the latest online malware.

To assess a product's impact on system performance, we used our custom OpenOffice benchmark test, which matches 20,000 names and addresses on a spreadsheet. We ran the test both before and after a product was installed, and then during the product's full scan and quick scan. (The test was run several times in each scenario.) We also measured how long it took each product to complete a full scan and a quick scan.

[Editor's Note: Best Buy has removed Kaspersky Lab products from its shelves, citing concerns regarding Kaspersky's alleged (but as yet undocumented) ties to the Russian government. However, until we see evidence that Kaspersky software is a threat to consumers, we will continue to recommend it. Here is further clarification of our position.]

    No you dont. I've never bothered with using a separate Av or firewall. I'm still here.

    They're all a waste of money. NOD32 is probably the only one worth getting. If I did use t

    Whether you're running Windows, macOS or Android, you need antivirus software. The question is what you want -- and how much you should pay.

    Yet another silly thread. If you have Windows installed, use Defender... period. Stop listening to all the third-party marketing hype. There is no need for anything other than what comes with the OS.

    I think customer service should be taken into consideration as well. Bitdefender is the worst, I bought it and the activation key wouldn't work, it took for ever to get it straighten out and they are quite rude.

    Fwiw, dealing with an issue now, of virus and/or malware, and after running bitdefender and it clearing what it found, I ran malwarebytes and it found over 10 more instances of malware. So though one shouldn't run live more than one at a time, I recommend having malwarebytes and run it periodically, too.

    Correction: including PUP's - from something called AnonymizerGadget - malwarebytes now found hundreds of more that bitdefender, avast and TrendMicro all missed when using their free online scan. And they aren't simply "potentially" unwanted programs, that AnonymizerGadget is defintely mal/spy/virus ware.

    I'm curious about why you didn't test Norton Internet Security. Not that I'm advocating it; indeed I look forward very much to spitting on Symantec's grave some day and only found this article while looking for alternatives. (That was after I found that Norton charged me three times for two subscriptions last year because they set up two automatic deductions on one of the subscription accounts. They then refused to refund the double payment because it was out of the "60 day guarantee period". Burn. In. Hell, Symantec.) However given that Norton would have a not-insignificant market share I would have thought that it would have been one of the ones to test. I would have been curious to see how it performed.

    Yup most of them are a waste of money.

    Doesnt matter what you get. And if you're stupid enough to use programs like Utorrent and get dodgy programs.

    Whats the point in having one anyway. Any AV program doesnt detect everything. And your system will end up infected anyway

    For people who seem to think anti virus programs are waste of time if they go on the internet and they depend on windows to protect them I would say there is a 99.9 percent chance they are already infected with some form of virus or malware. I have found that the better ones are VERY hard to breach and although it is still possible to get a virus the odds are slim to none. Without them your almost guaranteed you will pick something up in short order is just a fact in the modern age. The biggest issues I have is how much do they impact computer performance and how good is their detection. Some are like dropping a boat anchor dragging your computer down some almost unnoticeable. So instead of spreading viruses to all your friends and family get a good virus program and save yourself and everyone you know a lot of grief.

    Why isn't there a comparison chart? I've used Avast for years; it's free, and it's very good. Why did not Mr. Tom mention Avast as either better or worse than these paid products? My guess is that Mr. Tom is really acting as an advertiser. If he were "non-partisan", then I think he would provide a comparison chart or so to explain why it's worthwhile to pay for products like this instead.

    You can find dozens if not more reviews on AV programs all of them will vary on who and why they think one is better than another. If you want to believe Avast free is the top choice based on your experience you can find a review to tell you that. Tomsguide is just that a guide based on things they feel are important. Pay programs come with many more features! If you feel you don't need or want these features then without a doubt they are not a good choice for you. What I want and need in a AV is very specific and might not be suitable for you. Same for most people there is no ONE SIZE fits all. It does not make them dishonest or biased just makes them have their own opinion no more or less. I come to this site for their opinion for a good reason I respect there opinions whether I agree with them or not.

    bitdefender dont like it because forces to make an account and sign in before using it..like "meh rly?"
    Also does way to often background scans and updates like 10 times every day...

    I was running a repair and IT solutions shop a few years back. We regularly installed a free solution on MACs that came in, ahnd a busy week might see 5 - 8 Macs in the shop at once. Sophos free (which is what we used at the time) probably found nasties on around 60% of Macs that came in without protection. Make of that what you will, if you are in the "AV for mac is pointless" camp.

    Sophos auto-update is the worst. Hangs your computer until it completes. No way to stop it or schedule it. Kills productivity until it hopefully finishes or fails and you have to try again.

    AVG is a very good freebie. It finds viruses and scans emails. Yet, no mention. Then I scan with Malwarebytes, again free.

    so microsoft did not pay there way into getting the definitions from the independent security institutes it seems ... because no one heard about av-studios "optimizing" their results in these tests ... ever ...

    I agree that Kaspersky is far and away the best and nowadays uses the least resources . I don't know how they did it but it's amazing.

    Hi, I installed Norton Mobile AV on my Samsung S6 with Android 6.0.1 , but it's not helping with what I really wanted, which is to prevent my Chrome browser from being occasionally directed to random annoying sites. For example, one which says you have a virus, or one which says you won a prize. They don't do any damage, and I just ignore them and reopen the page I want, but it's the principle of the thing. How do I remove whatever malware is doing this? Thanks
