G’day,
Ummm … Windows, Word, Excel, Access, Powerpoint, Photoshop, Avast, Avira, AVG, CFP, Zone Alarm, Peer Guardian, etc. There would seem to be quite a number of users that prefer to use proprietary software. CSS or OSS, what really matters is the functionality, stability and integrity of the application (and not necessarily in that order).
Whilst Comodo is not located in the USA ........
When did New Jersey leave the Union? LOL. Comodo are headquartered in the USA and also have offices and labs in England, India, China and the Ukraine.
you still have to trust a vendor who could have built backdoors into the software.
Why would a company, whose primary commercial activity is based around authentication and trust, build a backdoor into a product? The presence of any backdoor would inevitably be detected and publicised. To me, this is akin to the old furphy about AV vendors creating viruses.
I’ll leave your comments about homeland security alone, as I am fortunate enough to live elsewhere. 
I've seen SO many bugs and design mistakes in your other products (CAV 2.0.17.58, CFP 3.0.12.266, BO247, CIS 3.5.52764.414 RC1) that I NEVER would trust your Diskshield and NEVER your FDE
CAV 2.0.17.58 - beta software
CFP 3.0.12.266 - beta software
BO247 - gold release software
CIS 3.5.52764.414 RC1 - beta software
I’ve tracked every post made under your user ID and I can’t find any post of yours that mentions an issue with BOClean. Was that posted under the same user ID (R.I.P.)?
As an IT professional, I’m certain that you appreciate that beta software can, and frequently does, causes problems. As a result, they should never be used in a productive environment or used on your primary PC.
Yes, there are issues with earlier beta versions of CFP, earlier beta versions of the now defunct CAVS2 and with current beta versions of CIS. Comodo welcome constructive criticism and invite you to become part of the community and assist them in identifying and eliminating the deficiencies you’ve mentioned.
Having said that, I would respectfully ask you to tone down some of your responses (and this applies to those who responded to your posts in a similar manner). It may be OK to think someone is ignorant, but it’s generally not advisable to actually call them that. OK?
Cheers,
Ewen
