You have an alert. Your SIEM or AV console shows hacktool.vulndriver 1.d7dd -classic- . Do not panic. Follow this IR checklist:

: If you didn't manually install a hardware tool or specialized software recently, delete the file immediately Verify on VirusTotal : Upload the specific file to VirusTotal only Rising

The detection does automatically mean your system is hacked. It means a vulnerable driver file exists on disk.

When you see the specific variant you are likely looking at a heuristic detection. Antivirus engines use specific alphanumeric tags to track variants of exploits. The "-classic-" suffix usually implies that the security software has detected a known, established technique or a specific driver that has a history of exploitation, as opposed to a new, zero-day variant.
