Internet software cookies are bits of information stored on your
computer
whenever you visit webpages while browsing. This can cause some some
privacy issues as
this can allow websites to track and log your browsing habits and
history. Along with your internet cookies, your
computer also stores your web history, cache files including pictures
and videos that have been viewed, search engine history,
web addresses, and password information whenever you browse the web.
These may have been accumulating ever since you began using
your browser, and these files can also waste large amounts of your hard
drive space without you even knowing it, slowing down
your pc performance! Anyone who shares your pc with you can tell where
you have been browsing on the web, especially if they decide to
snoop or accidently stumble across these files or registry entries. Java
applets or ActiveX controls can also be
left behind on your pc, and various other entries can be left hidden in
your system registry. ActiveX controls can be
particularly dangerous because they are executable files which run on
your pc.
