Clicking an unknown link can expose your device to malware, drive-by downloads, and phishing in a single tap. The safest move is to scan the URL for malware first — without ever visiting it. This guide shows you how to check any link for malware and viruses for free in seconds, what a real URL scanner actually checks, and the warning signs you can spot yourself.

How to scan a URL for malware (free, no signup)

Checking a link for malware takes a few seconds and no account:

Copy the full link — right-click and choose “Copy link address”, or long-press on mobile. Do not click it.
Open the malware URL scanner (or paste it on the URLScans homepage).
Paste the URL and press Scan.
Read the verdict. You’ll get a clear Safe, Suspicious, or Malicious result, the score, and the exact reasons behind it.

That’s the whole process — a free URL virus scan that runs against real threat intelligence instead of you gambling on a click.

What a URL malware scan actually checks

A good malware URL checker does far more than a single blocklist lookup. When you scan a link with URLScans, it evaluates the destination against multiple independent sources:

Google Safe Browsing — Google’s database of known malware, phishing, and unwanted-software URLs.
PhishTank — a community-verified phishing database.
17+ threat-intelligence feeds of known-malicious domains, refreshed daily.
Structural heuristics — typosquatting and look-alike (homoglyph) domains, abuse-prone TLDs, brand-new domains, login/credential lures, and gibberish hostnames.
Redirect resolution — it follows shorteners and redirect chains to the real destination and scans that, so a short link can’t hide a malicious target.
Direct-download detection — it flags links that point straight at an .exe, .apk, .msi, or .scr installer, a classic malware-delivery pattern.

Because these signals are combined, a URL malware scan catches threats that any single check would miss — and it explains why a link was flagged.

Warning signs a link may contain malware or a virus

Even without a tool, a few red flags should make you scan before you click. A link is more likely to be malicious when you see:

An unexpected file download — a link that immediately downloads an .exe, .apk, .scr, or password-protected .zip.
Look-alike domains — paypa1.com, microsoft-support.xyz, or a brand name buried in a subdomain like paypal.login.example.com.
Shorteners that hide the destination — expand the link first with a redirect checker or short URL expander.
New, random, or cheap TLDs — many scams live on .top, .xyz, .zip, or freshly registered domains.
Urgency or reward bait — “your account will be suspended”, “you’ve won”, “verify now”.

See any of these? Don’t click — run a malware scan on the URL instead.

Scan a link for viruses before clicking — on any device

The scanner works the same on desktop and mobile, so you can check a link straight from an email, SMS, chat message, or a QR code before you open it. This is especially useful for the riskiest links people receive: shortened URLs, QR codes on flyers or parking meters, “delivery problem” texts, and unexpected attachments. Copy, paste, scan — then decide.

Why scanning beats “just opening it carefully”

Visiting a malicious page can be enough to trigger a drive-by download or hand over data through an embedded form — you don’t always get a second chance to back out. A URL malware scan checks the link against threat intelligence and structural signals without loading the page in your browser, so you find out it’s dangerous before you’re exposed. For a broader safety check you can also use the website safety checker or phishing link checker.

Frequently asked questions

Can I scan a URL for malware for free?

Yes. URLScans lets you scan any URL for malware and viruses for free, with no signup and no daily limit. Paste the link at urlscans.com or the malware URL scanner and you get an instant Safe / Suspicious / Malicious verdict.

How do I check if a link has a virus or malware?

Copy the full link (don't click it), paste it into a URL malware scanner, and run the scan. URLScans checks the link against Google Safe Browsing, PhishTank, 17+ threat-intelligence feeds, and dozens of heuristics (typosquatting, suspicious TLDs, credential lures, redirect chains, direct executable downloads) and returns a verdict in seconds.

Is it safe to scan a suspicious or malicious link?

Yes. You only paste the URL — you never visit the page yourself. The scanner evaluates the link against threat intelligence and structural signals, so you stay protected from drive-by downloads or credential-harvesting pages.

Does the URL malware scanner work for shortened links (bit.ly, t.co)?

Yes. URLScans follows redirects and URL shorteners to the real destination and scans that final page, so a short link can't hide a malicious target from you.

Can I scan URLs for malware in bulk or with an API?

Yes. A free API key (1,000 scans/month, no credit card) is available at urlscans.com/register, so you can automate malware URL checks from scripts, security tools, or your own app.

What is the difference between a malware scan and phishing detection?

Malware checks look for links that deliver harmful files or code (drive-by downloads, trojan installers). Phishing detection looks for pages that impersonate a brand to steal your login or payment details. URLScans flags both in a single scan.
