ESET online scanner follows ntfs symbolic links and junctions. That is okay to a point, but if the link target is already in the scan hierarchy, or more than one link is present to the same data in a scan hierarchy, the data is scanned two or more times. It would be nice if the product would determine targets, keeping an internal list of targets scanned, and scan only once. I have no idea what a file link would do under these circumstances. I am assuming that the home ESET security product will do the same thing. I've not tested it yet. I am in the market for a high quality antivirus solution that requires as little time to maintain as is possible, and has as short of a scan time as is possible, and works! I have several junctions/symbolic links that I've created in directory structures for the convenience provided, and these obviously point elsewhere. Microsoft does the same thing for other reasons. Thanks!
