Comodo Firewall 10.1.0.6474
Changes:
- Creates QualityCompat key as required by Microsoft Meltdown-Spectre patch KB4056892 upon installation and update. Last production version 6420 is fully compatible with Meltdown-Spectre patch in all operating systems..
- Internet Security Essentials (Protection against Man in the Middle attacks) is now optional (selected by default) and can be found in Components section during installation.
- GeekBuddy setup is completely removed. It was optional and not selected by default. If you don't have GeekBuddy installed and you access Live support, it will launch Geek Buddy chat window in default browser.
- "Manual Scan" scan profile now has heuristic option de-selected by default, same like "Full Scan" profile.
- In Rating scan, when you see untrusted certificate listing, name will come from "Issued To" field of certificate rather "Friendly name" section. Trusted Root Certificate are listed by "Issued To" field and thus easier to find.
- Due to various incompatibilities, "Enhanced Protection Mode" is removed from HIPS settings

Improvement with file upload issue:
- We have had frequent issues with file uploading in CIS and this release aims to fix it for ever, following are changes made:
a) Max file upload limit is set to 128MB
b) There are some client side changes to improve performance of back-end; as updates propagate we should see improvement in file submission
- Improved detection of untrusted certificates. In last release we introduced Untrusted Certificate scan in Rating scan. But it could show legit certificate also. In this release we have updated logic and we can avoid showing known trusted certificate as untrusted as stated here. e.g. In this release, you won't see false-detection as reported here. That's the only one exception for now. Please report if you have any legit cases detected and we can put that in exclusion list

Fixes:
- XP BSOD as reported here
- Fixed crash as seen while browsing www.bankia.es/ as reported here
- Error with Chinese Translation as reported here
- BSOD as reported by 'Huolsam' here

- If you disable "check for database updates" option from "General Settings --> Updates" section, Trusted Vendor List update check will also not be made

Also we have moved "shell code injection detection" and "browser configuration modification" settings under this section.
