Antivirus software is nearly as crucial as a PC’s operating system. Even if you’re well aware of potential threats and practice extreme caution, some threats just can’t be prevented without the extra help of an AV program—or a full antivirus suite.
You could, for example, visit a website that unintentionally displays malicious ads. Or accidentally click on a phishing email (it happens!). Or get stung by a zero-day threat, where an undisclosed bug in Windows, your browser, or an installed program gives hackers entry to your system.
We’re not suggesting that PC security software is fool-proof. Antivirus software often can’t do much to stop zero-day exploits, for example. But it can detect when the undisclosed vulnerability is used to install other nasty bits, like ransomware, on your machine. Anyone who actively uses email, clicks on links, and downloads programs will benefit from an antivirus suite.

Nvidia’s new GeForce RTX 30-series laptops are finally here, and while they’re no longer equivalent to their identically named desktop cousins, this new breed of GPUs is still formidable, as our RTX 3080 mobile review proves. Even better? Unlike desktop graphics cards, you can actually buy them!
Well, some of them. Most of the GeForce RTX 30-series we’ve spotted so far come paired with Intel’s potent, yet older 10th-gen Comet Lake H gaming processors. New AMD Ryzen 5000 Mobile and Intel Tiger Lake H35 gaming processors were announced at CES 2021, but they’re not available quite yet—though the page for Asus’s intriguing Ryzen 9 5900HS-powered ROG Flow X13 laptop and its complementary ROG XG Mobile graphics dock teases that they’ll be available soon, and we’ve already got a review unit in our hands.

Nearly 7 percent of all U.S. Xbox game consoles were resold on auction sites along with nearly 50,000 GeForce 30-series cards in recent months, according to a new study.
We covered data scientist Michael Driscoll’s initial scalper report in December. In newly published data, it appears that some 113,220 Xbox game consoles were resold on auction sites eBay and StockX, spanning both the “Xbox One” and “Xbox Series” generations. That’s enough to equal 6.85 percent of all Xboxes sold in the United States. Nvidia’s new graphics cards were almost as hot as Xbox consoles, with an astounding 49,580 Ampere GPUs resold on auction sites, according to Driscoll’s numbers.

Q: I’ve had my computer several years now, and I was wondering if I needed to clean it—and if yes, the right way to do it.
A: Over time, computers do accumulate dust (and fur, if you have pets) within their interiors. This happens because the intake fans suck in air to help cool your system, and any free-floating particles in your environment get pulled in, too. As a result, in multi-pet or smoking households, build-up can pile up faster. Same too for homes in areas with big wildfires.
Layers of grime can reduce the efficiency of fans, which can in turn affect your PC’s performance, so it is ideal to clean them semi-frequently. For folks with less particulate in the air, that can be once a year. For others, it may be several times a year. The easiest way to figure out a cleaning schedule is to visually inspect your machine. If you can see a thin spread of dust on your parts, it’s time. Do that often enough and you’ll know about how often to check up on your PC.

The $450 GeForce RTX 3060 Ti FTW3 Ultra stands as EVGA’s best-in-class initial offering for Nvidia’s fantastic 1440p GPU, shipping with a healthy factory overclock and extra sensors that provide temperature readings for areas throughout the graphics card.
EVGA attacked the 3060 Ti FTW3 from a different angle than it did for its beefier RTX 3070 and 3080 cards, however, as well as most of the aftermarket 3060 Ti models we’ve seen so far. While those pricier FTW3 incarnations come loaded with massive coolers and just-as-massive premiums, the 3060 Ti FTW3 Ultra opts for a more restrained design that should fit into even tiny gaming PCs. Better yet, EVGA charges a mere $50 extra for the FTW3’s improvements—a smart call, as it avoids pushing too close to the (ostensibly) $500 starting price of the step-up GeForce RTX 3070.

In the battle for the fastest gaming mouse, Razer just fired the first shot in a new front. The $80 Razer Viper 8K boasts a wild 8,000Hz polling rate that’s eight times faster than the industry standard, paired with a blistering 20,000 DPI (dots per inch) sensor. Holy smokes. While esports pros should immediately start drooling over specs like that, most people will never come close to utilizing its full potential, especially since you’ll need a fairly beefy PC setup to get the most out of it.
That’s not to sell the Viper 8K short, though—it looks like a very impressive piece of kit. Polling rates measure how often your mouse tells your PC when its cursor is located onscreen. Standard 1000Hz mice take about one millisecond to do so, but the Viper 8K’s high-speed USB controller causes that input delay to plummet all the way down to a mere 1/8th of a millisecond, theoretically providing smoother tracking. Paired with that 20,000 DPI sensor, this mouse can almost move where you want it before you know you want it there in the hands of top-level esports competitors.

The Adata XPG Gammix S70 is a very fast PCIe 4 NVMe SSD that’s also considerably more affordable than the competition. Alas, in a first for an NVMe SSD—there are some fitment issues due to a massive non-removable, pre-installed heat sink.
This review is part of our ongoing roundup of the best SSDs. Go there for our top picks, and for information on competing products and how we tested them.
The drive inside the massive heat sink is your standard M.2 2280 (22mm wide, 80mm long) SSD using an Innogrit IG5236 controller, and 96-layer, TLC NAND. There’s 1GB of DRAM cache per terabyte of NAND, and about 33 percent of the NAND can be treated as SLC for secondary caching purposes—333GB for the 1TB version and 666GB for the 2TB version I tested. That’s with the drive empty; as it fills up, those amounts will drop.

The Galaxy S21 might be the smartest phone Samsung has ever made. Like the iPhone 12, it doesn’t have the best specs or the biggest screen. But it delivers where it counts, at a price that’s very attainable for a phone with a full complement of 5G, a high-end camera, and the latest Snapdragon processor. At $800, $29 less than the iPhone 12, and just $100 more than the Pixel 5 and Galaxy S20 FE, the S21 is already a strong contender for smartphone of the year.
Android and Galaxy enthusiasts will moan and wail over the things that are missing, which is admittedly a pretty lengthy list: 12GB of RAM, QuadHD+ resolution, expandable microSD storage, MST payment support, earbuds, a glass back, and a charger. But if you aren’t the kind of person who dives deep into spec sheets, the S21 will give you everything you need in a 2021 smartphone at a price that won’t make your eyes water.

Intel started shipping its first Iris Xe graphics cards to PC manufacturers on Tuesday—a fantastic milestone for the company’s newfound push into discrete GPUs. But shortly after we covered the announcement, the company delivered a major bummer of a clarification: Intel’s first graphics card won’t work on AMD-powered systems.
“The Iris Xe discrete add-in card will be paired with 9th-gen (Coffee Lake-S) and 10th gen (Comet Lake-S) Intel Core desktop processors and Intel B460, H410, B365, and H310C chipset-based motherboards,” an Intel spokesperson told PCWorld. “These motherboards require a special BIOS that supports Intel Iris Xe, so the cards will not be compatible in other systems.”

In this episode of The Full Nerd, Gordon Ung, Brad Chacos, and Adam Patrick Murray render judgement on the powerful CPUs and GPUs you’ll find inside the next generation of gaming laptops.
We kick things off with a deep-dive into AMD’s Ryzen 5000 Mobile CPUs. Tune in (or hit that link) for an abundance of charts and discussion, but bottom line? For now, Ryzen 5000 is the ruler of all it sees. You can’t squeeze Intel’s current 14nm 8-core CPUs into laptops this thin, nor this light.

We are terrible at passwords. We suck at creating them (the top two most popular remain “123456” and “password”), we share them way too freely, and we forget them all the time. Indeed, the very thing that can ensure our online security has become our biggest obstacle to it. This is what makes a good password manager essential.

Nvidia’s next-gen graphics have finally arrived in notebooks, and as you can see in our GeForce RTX 3080 laptop GPU review, the mobile version of Team Green “Ampere” architecture spits out frames at blazingly fast rates. But the performance you get from mobile RTX 30-series graphics chips won’t necessarily be equal, even between two laptops with the same hardware inside.
One GeForce RTX 3070 laptop might not be as fast as another, for example. And it’s even possible that in some cases a slower GPU could theoretically be faster than pricier models. Yes, you might (might) see a GeForce RTX 3070 laptop that can match or possibly outperform an RTX 3080 laptop in some games, though we’ll need to see more reviews trickle in before we can state that definitively. Regardless, you’re going to want to do a lot more homework than before when you’re shopping for a gaming laptop.

Samsung’s Exynos processors have never quite been able to live up to their Snapdragon counterparts. Whether we’re talking about the 990 in the S20 or the 850 in the A21s, Qualcomm’s chips have always enjoyed a comfortable lead when it comes to power and performance.
That might be changing with the newest Exynos 2100 processor that powers the Galaxy S21 phones around the world. Samsung made a bit of a splash during the launch of the chip, declaring “Exynos is back” with a processor that “sets a new standard for premium mobile experiences.”
