I'd argue Comodo isn't a security company. It's a software company that markets software which intends to have a positive effect on one aspect of your security (namely, malware). They're using 20 yearold ineffective techniques to do attempt to have a positive effect on your security, and whether there is a positive, negative, or neutral net effect is to be debated.

They continue to make hundreds of millions of dollars, so they keep going.
