Revisium PHP ScanBot

Revisium PHP ScanBot targets a specific, real problem: a website owner who suspects their site has been hacked and wants to check a particular PHP or JavaScript file for injected malicious code, without wading through their entire codebase by hand. Its own profile states the scope plainly: "I know more than 500 kinds of malicious code for websites. I'm waiting for .php or .js files to check for viruses."

This is a different use case from the general link/file scanners elsewhere in this list — it is not for checking a random download or a suspicious link a friend sent you, but specifically for a webmaster auditing their own site's source files after signs of compromise (unexpected redirects, spam content appearing, a hosting provider warning). Revisium is a known name in the Russian web-security space specifically for hacked-website cleanup, which gives this narrow tool more credibility than an anonymous file scanner would have.

Because it is scoped to PHP/JS malware patterns rather than general-purpose antivirus signatures, it is a complement to a broader tool like Dr.Web or VirusTotal, not a replacement — use it specifically when you're auditing website source code, and use a general scanner for everyday downloads and links.
