[Issue] Requests of VirusTotal exceeded #1562
Description
Describe the bug
Since cf2b9d7686a0697005a58bbb15c1243d26e53e10b, on a file containing 180 lines, VirusTotal's quota of 500 requests is exceeded after only 70 requests.
Of these 70, only about 20 are effective. The others give me an error.
According to a discussion with support, the problem lies with the source code.
Regards.
