Thanks alot for replying….
I went on the site and it says
“If you are having problems opening VDB files, you should:A) Identify a program that can open the file andB) Check your PC for invalid registry entries and other speed issues”
I tried the 2nd option and it says the file is fine….no curroption
Ho do i find the program that can open it?

Any reason why you thought to imbed an unrelated semi-junk site in the middle of your comment? — Tom

Ah, I see. You just copy/pasted the “ad” from the site and the link was part of it. The link was unrelated to file extension .VDB. The filext site tells you that those types of files are opened by a couple anti-virus products. There is no known program that will process a .VDB file for you for reading. You have to write your own. — Tom

finding virsu definitions and making a database of my own is itself a project…isn’t it?…. my main focus here is to make the antivirus…so i need a predefined database for viruses….is there any other way or any other site can can provide me with some of the definitions….I am new to this…so I dont have much knowledge

virus defintions for android OS

I want to build an antivirus for android…so I need virus signature database…
 
First, I’m not aware that any Android viruses exist, so there shouldn’t be any signature databases that actually work. Further, I’m not aware of any way to have any AV program run on Android unless the device is rooted (which generally voids any warranty for the device).
 
There does, however, appear to be other non-virus types of malware that will run on Android, e.g., trojans. It’s not clear what your project would do about them nor how you would recognize them. For those, Android already warns the user about the activities and the user must approve those activities.
 
Would your project somehow try to stop a user from approving an app? How would it actually get that done? It’s not that easy to get one Android app to stop another app from installing or running.

I am very sorry for such a long delay…. I was going deeper as to what you suggested….and I guess I am not clear as to what will be my final project….but I was first planning to make an antivirus that would detect and probabily remove it….once I do it with one virus, i will be more clear with the working and all…..but before investing so much time in the part i just wanted to be sure, that there are virus signatures available for android readable by humans.

and I also went through net about android virus and though there are no operating system related virus(since it is linux based and very secure) but there are email, net virus, etc…. and even though sometimes android warns the user about the virus, users are not always well versed with how virus works, etc. and majority of them are amateurs ….so they tend to make mistakes…. I was thinking of being use at that time

…there are virus signatures available for android readable by humans.
 
I’m not aware of any signature files that are readable by humans.
 
You might try working with either the ClamAV project or the OpenAntiVirus project. If you learn how they use their signature files, you might see a way to handle signatures in Android.
