With the internet full of dangerous links and websites designed to infect devices with malware, it's important to be cautious and verify link safety before clicking.
Thankfully, there are various free online tools and best practices that can help you scan links and check for viruses or other threats before potentially compromising your device or data.
One of the best ways to check a link for malware is to use a URL scanning tool. URL scanners analyze links to look for signals that may indicate the site contains viruses, phishing attempts, spam, or other malicious content:
VirusTotal is one of the most well-known free online virus scanners. Simply paste in a link you want to check, and VirusTotal will scan it through multiple antivirus engines and websites to provide an overall safety assessment. The results will show if any issues were detected.
URLVoid offers free URL scans powered by Web of Trust, Google Safe Browsing, PhishTank, and more. It will categorize links as either safe, suspicious, or malicious based on over a dozen different threat intelligence sources.
PhishTank lets you check specifically for phishing attempts and known phishing pages. It maintains a constantly updated database of reported phishing sites.
While not as full-featured as other scanners, Google Safe Browsing is a quick way to check a link against Google's lists of unsafe sites. It can identify malicious pages or downloads.
In addition to scanning direct links, you can also use website malware scanners to check entire domains or web pages for threats:
SiteSafety by Avast lets you enter a website URL to scan the overall reputation and prevalence of threats detected on the domain. It checks hosting information, downloads, and links to paint a full picture.
Quttera scans websites using both its contextual detection engine and Google Safe Browsing data. Results include recent malware discoveries, suspicious codes, fraudulent links, and other identified issues.
The Sucuri SiteCheck scanner provides free website malware scans, looking for injected scripts, iframe redirects, blacklisting status, website errors, and other signs of compromise.
Norton Safe Web analyzes website reputation based on a variety of factors, including the presence of threats, spam, scam indicators, and inappropriate content. It provides credible safety ratings.
There are also various browser extensions and online tools you can use to get quick link scans right from your browser toolbar:
