Does it make any sense to virus scan a disk image?

Does it make any sense to virus scan a disk image? If I scanned the drive itself, I don't see the point of scanning the disk image at all. Am I wrong?

For that matter, does it make any sense to scan any compressed file? The compression should mess up the virus signature, don't you think?

 

I think it makes more sense to run all the VirusScan checks, Security Checks, and etc on your HD.... BEFORE making the TI Image Backup. If you did this, then I don't think you have anything to worry about.

I don't think compressing a Virus will destroy its signature. That's how most of them are introduced anyways. (Unzipping a file ...before running a Virus Check on it.)

 

I wonder if scanner can read inside the compressed file? Depends upon the file type.

 

Yes it can, decompression on the fly is straightforward to do.

F.

 

There are many imaging software so isn,t it that they use different sompressing methods. Can all these be decompressed by most of scanners?
