Frequently asked questions
Are the ScanWith tools really free?
Yes. Every tool and download on ScanWith is free to use with no account, no trial and no usage limits for normal personal use. The site is supported by ads.
How do I check if a link is safe before clicking it?
Paste the full link into the URL Scanner. It checks the address against Google Safe Browsing, URLhaus and VirusTotal and shows any phishing or malware reports in a few seconds.
Do you store the files, links or passwords I check?
Tools marked Client-side, like the Password Generator, run entirely in your browser, so nothing is sent to us. For URL, IP and hash lookups we send only the item being checked to the threat-intelligence sources and keep an anonymous hash of the result to speed up repeat checks.
Can an online scanner replace my antivirus?
No. Online scanners are a second opinion for a single link, file or address. Keep real-time antivirus running, and use a bootable rescue disk when malware stops Windows from starting.
What should I do if a scan finds malware?
Do not open the file or link again. Disconnect the device from the network, run a full scan with your antivirus, then follow our removal guides. Change any passwords you typed on the affected device from a clean one.
