- lmm 11y agoMicrosoft is doing the right thing. The whole point of that string is to trigger such behaviour. It's so you can use it to test that your antivirus is working.
- voltagex_ 11y agoShould it really tell the user that it's a dangerous file? Although if it didn't, malicious files could use that to their advantage.

- provemewrong 11y agoFrom the same Wikipedia article: >Anti-virus programmers set the EICAR string as a verified virus, similar to other identified signatures. A compliant virus scanner, when detecting the file, will respond in exactly the same manner as if it found a harmful virus. Not all virus scanners are compliant, and may not detect the file even when they are correctly configured.
