Speed of antivirus full disk scans

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
Can anyone tell me how the speed of a full disk scan is affected by the
ratio of shortcuts to files? Suppose we take NAV scanning a disk with
50,000 jpgs. Now we replace them with 50,000 shortcuts. Any difference
in scan time expected? How about MS doc files vs shortcuts?

ShortCuts are small files and are not really binary files.  They are only
pointers to
programs, data files, URLs and some embedded objects.  Usually they under 2KB.
They are
totally unlike JPEGS, DOC, PPT and other data files that can be any size.  You
just can't
compare them.  All you can  say is you can scan ShortCuts (.LNK, .URL, etc.)
much faster
because of their limited size.

Whay are you asking ?

Re: Speed of antivirus full disk scans

Machine has about 100s of 1000s data files. One option is to move most
files to an external USB disk and store their shortcuts on the main
disk. Once the files on the external are known to be OK, unplug the
external during full disk scan.

That will be fool hardy.  You STILL need to make sure the data files are
scanned.  Scanning
shortcuts is a waste of time and bears no benefit.

Once the data is known to be free of malware (assuming they are ALL data files
only) you
don't have to do "On Demand" scans on the drive of data.  However, you still
should be doing
"On Access" scanning such that they individual files being edited, viewed or
modified are
scanned as they are written or opened.

Re: Speed of antivirus full disk scans

The files are scanned before archiving. The shortcuts tell me where to
find them and because the shortcuts are small the full disk scan will
be quicker. They simply get scanned because they are there.

NAV pops up once a week to do a full disk scan and then keeps nagging
me to complete the scan. I like the reminder to scan, but not the
nagging, so I am looking for a quick way to complete the full disk
scan. I prefer an automatic process to having to remember to scan and
having to select and issue commands.

Look into changing the settings from scanning al disks to scanning all hard
disks and not
removable media.
