Are on-demand scans required?

    Hi,

    Here's the scenario:

    New build PC with ESS or EAV loaded up and running the on-access scanner, and being constantly updated over the internet.

    Question:
    If every new file written to the hard drive is now scanned by the on-access scanner, then theoretically there is no need to run/schedule any future on-demand disc scan.

    Is this true? Why do people still appear to perform scheduled full-disc scans?

    Thanks in advance.
    Mike

    Because the scanner might miss the virus when it was downloaded (No scanner is 100%) When you do a on demand scan later it could pick-up the missed virus. Just my 2 cents worth. I do a full system scan weekly.

    A bit of a worry if this is true, i.e. the on-access scanner may miss threats, isn't that what we're actually paying it to do??

    Any answers from someone within ESETo_O

    Since the startup scans check files that are run at system startup, malware that might be potentially running should be discovered immediately after an update which already recognizes that malware. However, it's a good practice to run a full disk scan from time to time when the computer is idle.
