During my weekly round of gathering zero day malware for my zoo I came across 2 files that, although they were able to be downloaded to my computer, were detected by Comodo AV on a manual scan. I then uploaded both files to Virustotal and was surprised to see that VT shows these same files as not being detected by CAV:
Just wanted to bring this to your attention, and thank you for CIS!!!
Thank you for reporting this. We’ll check it and get back to you.
If you would like the samples let me know. I have them saved.
VirusTotal uses a bit older version and as a result there are small exceptions like this one that may occur.
