Virus detection

I am evaluating a few different AV packages with a view to moving away from Symantec Endpoint Protection which I am unhappy with. As part of my evaluation of each package I have downloaded a collection of viruses from virussig.com and scanned them to see how many are identified.

With Sophos, if I create a new scan and include just the folder containing the viruses (sub-folders are automatically selected) it doesn't find a single virus. However, if i right-click on the folder and select Scan with Sophos Anti Virus, it detects 579 viruses (incidentally Kaspersky found 2600 in the same folder but that's a differnt matter). Can anyone explain why the normal  scan doesn't find these viruses but the right-click does.

Thanks

  • Hello TimRay,

    first of all (apart from the fact that I don't know who virussig.com is as the domain comes and goes :smileyhappy:) sensible evaluation of AV products against a collection of threats is not a simple task. With literally millions of threats and variant scanning "just" a few thousand items has no real significance. 

    There's a major difference between scheduled/immediate and right-click scans: A scheduled scan per default scans only certain types of files and does not scan inside archives - a right-click scan scans all files and inside archives. How did you set up the "normal" scan?
