Looks like the antivirus is up:
More than likely a repeat of the following scenario:
I know that Avast don’t use the same definition for v4 and v5. Look at the screen shot or VT result .
I don’t know about other AVs.

None of those version pairs have definition update formats which are any more compatible than Comodo. For best results, refocus your frustration on the shortcomings that lead you to wish they were! ;D
I don’t doubt your sincerity but the “This is a free product.” mantra really doesn’t cut it when other free products are comparatively free of bugs as well as cost. 
I know for a fact that AVG is using a definitions that is compatible with older versions of it’s product I tried there latest version and it eats up to much cpu and slows down your computer I also have a old installer of version 7 and yes it can get definitions updates. It will bug you to upgrade the program but you can still get definitions for version 7. and it will still scan your system with the new definitions in its data base.
Hi MJR1
You did say definitions for AVG 6 and 10 were compatible. Now it’s that you can still get updates for 7.X ??? which I would not recommend.
If it’s gotta be free (for personal use) and work well on an old slow PC, putting on my “objective as can be expected under the circumstances” hat - hmmm… it starts with ‘a’ and a guy who is far more ridiculously fanatical than I could be bothered about as far as reducing resource use has got a whole thread about it here
You can get the new Anti-Virus Definitions for 6 or 7 and use them to scan your computer with the older version of AVG but it will bug you there is a newer version of AVG out there and do you want to get it. And a long time friend of mine told me that where AVG went wrong is they got away from just a Anti-Virus program and added to much other monitoring stuff to there software and that is why it has your cpu running at 60 to 70 percent most of the time. Now that is the more recent one the older version doesn’t do that.

i wish comodo wouldnt create so much hype about what they are developing then not tell us anything about it. they just say very vague things about it and say it will be released soon. atleast tell us some details and if not then dont even announce it.
And if they did that, people would complain about them never telling “us” anything.
If they announce a specific date and it slips, people complain about that.
They, like most software companies, are ■■■■■■ if they do and ■■■■■■ if they don’t.
I don’t know if there actually is an acceptable medium here.

Good point. Also, people need to remember that if Comodo says that they are working on XYZ, then another company might go, “that’s a good idea” and rush to get it out even if it’s not perfect, just to be first, then Comodo can’t patent it or claim to be first. So, a lot needs to go on in the background that we cannot be made aware of before releases. So, when they have something workable, patentable, and presentable, then they will release information.
I think the happy medium would be an actual dev just stating, “We have read these bug reports XYZ, and are looking for fixes to them in the next release. Also the next release will contain new technology that we can’t discuss for these reasons …”. The bug reports one, would be replies to individual bugs I guess. 
Cheers.
I do believe this issue was stated by Melih not too recently ago somewhere here within these forums. Do not quote me on the precise wording but, I do believe that the reason for the hush hush on this has to do with copyright issues.

Trademarks more precisely. Doesn’t want DACS to be trademarked by someone else before they can do it.
Actually, copyright is the correct terminology to use here.
"According to the US Copyright Office FAQ, copyright “protects original works of authorship including literary, dramatic, musical, and artistic works such as poetry, novels, movies, songs, computer software and architecture.”
DACs is a new software architecture that is a basis of computer software and would correctly fit the criteria of “copyright” law.
i remember melih saying something about waiting for the patents for DACS first then releasing the details i just wonder how long that process takes and if its almost completed so they can release some details about DACS
Yes that is kind of what I was referring to in the beginning. And sometimes I know for a fact that the patent office or whoever is handling this matter can take sometimes forever.
yea it seems like the patent process takes quit some time. i wonder if that process is close to being complete. i wonder if melih or egemen knows?
Their DACS software is already copyright protected, even if it’s not complete. Any possible leaks of a beta build would be controllable via copyright(in theory :D).
Patenting is more sensitive, yet even without patent registration isn’t an issue until details of the system is either explained in-depth, or reverse engineered in order to reproduce its functionality, which still assumes it has to be available to public.
Trademarks are the most sensitive. They protect a name, and if trademark registration isn’t complete, anyone can come along and register it before Comodo does.
someone does. 88)
Many products are released before before the patent is issued, yet they are still protected for the most part. This is what Patent Pending means. It’s a bit of a warning for competitors to keep their hands off. Competitors can still use the basic concepts of the product until the patent is finalized, but unless they’re stupid, they’ll leave it alone because they’ll have to eat any production or R&D costs they’ve spent while trying to develop a copycat product before the patent is officially released. When the patent is finally released they’ll have to abandon their copycat product using the now patented technology.
