Summary

There are a lot of detected "Malware.XXXXXXXX" (XXXXXXXX for 8 random characters) on normal files in a short time.

Details

The issue is caused by memory corruption, which may be due to:

Third-party applications that load VSAPI unintentionally
Trend Micro products' threading issue i.e. products still scan the file during the pattern update or update multiple patterns at the same time

Memory corruption caused by third-party applications cannot be prevented, but Virus Scan Engine (VSAPI) has some mitigation measures to prevent the second condition. It was included in VSAPI hotfix 11.200 and VSAPI official 12.000.
