Low level of virus detection

Since the beginning of last year, I have noticed the lack of efficiency of F-Secure products to detect new threats, especially the .msi, .lnk, .htm and .vbs threats, and I believe that about 75% of new threats are passing through the F-Secure without being detected.

In Brazil, daily hackers create bank Trojans using the extension .msi, and lately when no threats with this extension are being detected.

In this link I am forwarding the samples that I already submitted to F-Secure and even today it does not have a vaccine.

    I had already released all the samples in this link, even so they did not release any vaccine
