Hi; Does the Comodo Firewall have the D+? I have used Comodo Internet Security before (year+ ago...did not install the antivirus. Used it in tandem with Avast free) and it had D+. I do not remember seeing one before but that was I think the early versions(2.xx.xx or 3.xx.xx) of just Comodo Firewall. As mentioned before, I used D+ without the antivirus module last time I used CIS. If for example Comodo Firewall(just the firewall) has D+ and I opt to use it, does it equal CIS w/ D+ and w/o antivirus as well? Thinking of using CIS ver 4.1 in an old system with either Avira Personnal/Avast free ver5 with PrevX 3.0. What may be a decent setting so that it will be compatible with all three security softwares..say with; (a) CIS ver 4.1-- w/ D+ and w/o antivirus, Avira Personnal, PrevX 3.0 and Sandboxie (paid version) (b) CIS ver 4.1-- w/ D+ and w/o antivirus, Avast free ver5, PrevX 3.0 and Sandboxie (paid version) AND, one last important question. Has Comodo improved it's explanation on it's pop-ups? For a not so "learned" pc user it may seem cryptic and if no explanation is given may just hit "Allow this request" to get rid of the pop-up. Please see a good example by aigle: https://www.wilderssecurity.com/showpost.php?p=1444190&postcount=115 Your guidance is humbly requested. Thanks in advance!
