🦪 AV & Malware Testfiles

Standardized test files to verify your antivirus, malware scanner, and content inspection policies. These files are completely harmless — they contain only official test strings or demo content recognized by all major AV engines.

Safe: None of these files contain real malware, exploits, or executable code. EICAR is an industry-standard test string published by the European Institute for Computer Antivirus Research.
