The Short Answer
No, Hooda Math is not a virus. It's a legitimate educational website focused on math games for kids, usually ranging from elementary through middle school level. The domain is hoodamath.com and it's been around for years. Here's what actually happens when people get suspicious. They or their kid click on a game, and suddenly a pop-up shows up asking about notifications. Or sometimes an ad looks like it's from Windows or Chrome and asks you to call a "support number." That's not Hooda Math doing anything malicious - that's third-party ad networks doing their usual thing. The site itself doesn't bundle malware. I ran into this with a student's laptop last year. Parent thought the browser was infected because every time they opened a new tab, there were redirect ads pushing fitness supplements. Checked the actual Hooda Math game pages directly - clean. The issue was a browser extension they'd installed months ago from some random deal site. Removed the extension, cleared the notification permissions in Chrome settings, and the redirects stopped immediately. Hooda Math was never the problem.
Still, I'd be remiss if I didn't mention the reality of running ad-supported education sites. The ad load on Hooda Math can be heavy, especially on mobile. Some of those ads are sketchy by association. You'll see pop-ups for questionable apps, fake update buttons, and the usual browser notification spam. None of it means the site itself is compromised, but it means you should have an ad blocker if you're spending real time there. uBlock Origin works fine on desktop. For mobile, either use a browser with built-in ad blocking or accept that you'll see more junk. One thing people miss: the actual game files are just HTML5. Nothing to download, nothing to install. If you see a prompt asking you to download anything from Hooda Math, close it. The games run in the browser. Any download link you encounter is almost certainly an ad masquerading as a game installer. I've seen it multiple times - a button labeled "Play Now" that's actually a separate ad frame overlapping the real game button. Just wait a second for the page to fully load and look for the actual game iframe before clicking. There's also the question of whether these sites collect data. Yes, they do. Standard analytics, ad tracking, the whole thing. If privacy is your concern, that's a separate issue from the virus question. Using an ad blocker reduces tracking significantly. A DNS-level blocker like NextDNS or Pi-hole would cut even more out. But again, that's privacy, not security.
If you're worried about your kid's computer specifically, run a scan with Malwarebytes just to put your mind at ease. It takes about ten minutes and will confirm whether anything unwanted is actually on the machine. In my experience, the result is almost always that the system is clean and the real culprit is notification spam or an ad-heavy browsing session.
