Ok, here is my problem and maybe one of the devs can chime in. I have a folder with over 3000 malware that is undetected by comodo. Now, I have scanned this folder with comodo DB 1215 and heuristics on high but it does not find anything else. When I run the a scan with avira on this same folder and comodo is on stateful, comodo starts popping up red boxes as avira is going over some files. What this means is that comodo does have the signatures but the AV engine cannot find them. What is going on?
Few weeks ago I had the same experience.
I scanned the folder using CIS on-demand scanner and nothing was found. But on-access scanner of CIS detected viruses (actually worms) when the same folder has been scanned by DrWeb CureIt.
At the moment all these virus examples are removed from my computer. But please let me know, if you need them for testing (I’ll try to find them on the computer, which was “the source of infection”).
1 - What is your operating system?
2 - Does this happen in other PCs with this specfic set of malware too?
3 - If you can reproduce this all the time, would you be willing to have an EasyVPN sesion with me o that i can closely diagnose it? Please PM me for this.
I did find what i think is a diffrent bug, heuristics scan before DB on my test machine, how did i notice this
I scaned a file and got Heur.Packed.Unknown then i turned Heuristics off and got a trojware.w32.something, so why does Heur scan first?? ???
I will see if i can do it again. just tested and yes i can do this multiple times on diffrent system also.
Ok here is the deal, avira is somehow about to scan password protect archives (zip/rar), and comodo is not. I had some ZIP files infected with worms, but I didn’t have the password for. I cracked them and once I extracted them to a folder on-demand easily found them. So, I don’t know how avira does it but it does. Maybe comodo should look into having something like this too.
