CIS does not have a so called web shield. That is by design.

Comodo does not believe in having various shields. They only make a computer slower. It is Comodo’s believe that detection on disk or memory access is sufficient.

That makes your comment an item for Wishlist - CIS rather than a bug report.

And the item in the antivirus settings, “do not scan script files larger than (MB)” ?

See the picture attached in this post.

Thank you very much for your report in standard format, with all information supplied. The care you have taken is much appreciated by Comodo, and will increase the likelihood that this bug can be fixed.

Developers may or may or may not communicate with you in the forum or by PM/IM, depending on time availability and need. Because you have supplied complete information they may be able to replicate and fix the bug without doing so.

Moved to Verified.

Many thanks again
