If you use a social network, a Web browser, a public computer, or a cell phone, you’re
in grave danger of falling victim to attacks on your PC, your bank account, your personal
privacy, and more. Here are 17 common threats and the fixes to defend yourself.

Antisocial Social
Networking
A message from one of your friends appears in your
in box, sent via a social network site that you use regularly.
Th e message promises a big laugh and points
to a Web site you’ve never heard of. You click the
link—and the next thing you know, your PC is misdirected
to a phishing page that steals your log-in de -
tails or to a drive-by download site that infects your
system with a password-stealing Trojan horse. And
your friend says that she never sent you the message.
(fix)
If you think that details
of your so cial networking account
may have been stolen or compromised
in some other way, report
your suspicions to the site’s support
team immediately. Change
your password frequently, and
avoid clicking message links that
purport to transfer you back to
the social network site. Instead, to
get back to your account, type the
site’s address di rectly into your
browser (or follow a bookmark
that you saved previously) .

Quote: You may have nothing to
hide, but that donot
mean that your browsing
history won’t get you in
trouble. Out of context,
entries in a list of
sites you recently
visited are easy to
misconstrue.
(fix) Try using
your browser’s private
browsing feature—
but don’t
depend on it. Long a
feature of Apple’s
Safari browser, private
browsing lets
you surf the Web
without leaving a
trail of Web site
addresses behind.
Once you turn on
Private Browsing in
Safari, Apple says,
you’ll leave no trace
of the sites you visit.
Add-ons for the Firefox
browser offer Windows
users the same benefi ts:
An app called Distrust
(fi nd.pcworld.com/62347)
gives users of Firefox 2.x
and 3.x a way to manage
their browsing history;
some fi les that Firefox
temporarily writes to disk
aren’t erased until the
browsing session ends,
however. Firefox 3.1 (now
in beta form) is likely to
add more-comprehensive
private browsing features
to the browser itself. Two
add-ons—’Private Browsing’
and ‘Toggle Private
Browsing’—provide granular
control over settings
to help users
manage the new
features. (Warning:
In re cent testing by
a se curity fi rm to
see which browsers’
tools do best at
protecting against
tracking by visited
Web sites, Firefox,
Google’s Chrome,
Microsoft’s Internet
Explorer 8 beta,
and Safari all fared
poorly, with Safari
in last place.)
But no browser
can completely prevent
inquisitive sites
from tracking your
visit. For maximum anonymity,
try the fee-based
Anonymizer (anonymizer.
com) or the free Tor (fi nd.
pcworld.com/62344). |
