Is crystaldiskmark.us legit or a scam?
A malicious impersonation of the CrystalDiskMark utility that distributes malware and is flagged by 13 major antivirus engines.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

Tech-support scam — do not call
15 of 92 antivirus engines flag this page (13 outright malicious). Microsoft, Apple, and your ISP never call or pop up to ask for remote access or payment. Don't call any numbers shown, don't install "support" tools, and close the page — ideally by ending the browser process.
Website Preview
Automated page render — captured in a safe sandbox. What an ordinary visitor would see when loading the site.
MT Intelligence
The site is a clear impersonation of the legitimate CrystalDewWorld project, using a '.us' TLD instead of the official domain. Our antivirus network shows a high consensus of danger, with 13 engines including BitDefender and ESET flagging it for phishing and malware. The page lacks any verifiable contact details, such as an email or phone number, which is a common trait of software-impersonation scams. Furthermore, the site is not indexed in global traffic rankings, suggesting it is a recently created or low-reputation domain used for malicious distribution. The presence of tech-support scam markers in our analysis further confirms its fraudulent nature.
