hi,
Recently i have experienced problems with the Internet Explorer 6. Everytime
i turn on my computer my default home page has changed to (
www.easypic.org) i
tried restoring it but with no luck. New favourite sites has been added
containing adult material. When i am browsing net for like 15 minutes, i keep
getting redirected to a porn site and new programs are installed in my
computer even though my internet security levels are set to medium. I tried
removing the 'porn dialers' from my pc but when i browse the net again they
reappear. My specs are as follows Windows XP home edition SP1. Plz could
someone help because my children really want to use the net. Thanks
Daniel,
You have a an adware / spyware infection. This is a common problem, but will
require some work, including behaviour modification.
Start by downloading each of the following free tools:
AdAware <
http://www.lavasoftusa.com/>
CWShredder <
http://www.majorgeeks.com/download4086.html>
HijackThis <
http://www.majorgeeks.com/download.php?det=3155>
LSP-Fix and WinsockXPFix <
http://www.cexx.org/lspfix.htm>
Spybot S&D <
http://www.safer-networking.org/index.php?page=download>
Stinger <
http://us.mcafee.com/virusInfo/default.asp?id=stinger>
Create a separate folder for HijackThis, such as C:\HijackThis - copy the
downloaded file there. AdAware, CWShredder, and Spybot S&D have install
routines - run them. The other downloaded programs can be copied into, and run
from, any convenient folder.
First, run Stinger. Have it remove any problems found.
Next, close all Internet Explorer and Outlook windows, and run CWShredder. Have
it fix all problems found.
Next, run AdAware. First update it ("Check for updates now"), configure for
full scan (<
http://forums.spywareinfo.com/index.php?showtopic=11150>), then
scan. When scanning finishes, remove all Critical Objects found.
Next, run Spybot S&D. First update it ("Search for updates"), then run a scan
("Check for problems"). Trust Spybot, and delete everything ("Fix Problems")
that is displayed in Red.
Then, run HijackThis ("Scan"). Do NOT make any changes immediately. Save the
HJT Log.

Finally, have your HJT log interpreted by experts at one or more of the
following security forums (and please post a link to your forum posts, here):

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix and / or WinsockXPFIx.
Finally, improve your chances for the future.
Harden your browser. There are various websites which will check for
vulnerabilities, here are three which I use.
http://www.jasons-toolbox.com/BrowserSecurity/
http://bcheck.scanit.be/bcheck/
https://testzone.secunia.com/browser_checker/
Block Internet Explorer ActiveX scripting from hostile websites (Restricted
Zone).
<
https://netfiles.uiuc.edu/ehowes/www/main.htm> (IE-SpyAd)
Block known dangerous scripts from installing.
<
http://www.javacoolsoftware.com/spywareblaster.html>
Block known spyware from installing.
<
http://www.javacoolsoftware.com/spywareguard.html>
Make sure that the spyware detection / protection products that you use are
reliable:
http://www.spywarewarrior.com/rogue_anti-spyware.htm
Harden your operating system. Check at least monthly for security updates.
http://windowsupdate.microsoft.com/
Block possibly dangerous websites with a Hosts file. Three Hosts file sources I
use:
http://www.accs-net.com/hosts/get_hosts.html
http://www.mvps.org/winhelp2002/hosts.htm
(The third is included, and updated, with Spybot (see above)).
Maintain your Hosts file (merge / eliminate duplicate entries) with:
eDexter <
http://www.accs-net.com/hosts/get_hosts.html>
Hostess <
http://accs-net.com/hostess/>
Secure your operating system, and applications. Don't use, or leave activated,
any accounts with names or passwords with trivial (guessable) values. Don't use
an account with administrative authority, except when you're intentionally doing
administrative tasks.
Use common sense. Yours. Don't install software based upon advice from unknown
sources. Don't install free software, without researching it carefully. Don't
open email unless you know who it's from, and how and why it was sent.
Educate yourself. Know what the risks are. Stay informed. Read Usenet, and
various web pages that discuss security problems. Check the logs from the
security products that you use regularly, look for things that don't belong, and
take action when necessary.

Paranoia comes from experience - and is not necessarily a bad thing.
