I don't think I'm paranoid, but I feel convinced
someone is accessing my laptop. I'm using a
Belkin router FSD7230-4 which I have set up with
as secure.
Sometimes (frequently, in fact) I come into my
study to see the lights on the router flickering
busily away, including the one marked Wireless .
When I check my hard-drive I see the amount
of space remaining keeps changing.
Could someone be accessing my laptop - looking at
private documents, and possibly downloading onto it
undesirable material?
Your hard disk may be buzzing due to all sorts
of normal processes, such as windows and antivirus
or anti-spyware programs updating or doing their
tasks, widows indexing files or Google desktop search
if you have it usually indexes files for easier
access (the reason for HD space changing...). Also,
Windows can get rid of temp files and other
files no longer needed from time to time...disk
space changes...
If no one can access the system unless with a
WEP / WPA access key, well, no one can access.
If you don't have file sharing enabled and your
firewall is on and all the rest of other
security procedures, I doubt if anyone is accessing
your files.
Generally, if your network is well protected and
secure, that should give you a piece of mind.
Some routers (depending on ISPs) have flickering
lights going on as an indication that they are
busy updating your ISP's software or changing IP
addresses etc.
