IE6 Search Hijack

S

(Warning - readers are cautioned not to try to reach the URL mentioned
in this post, especially the IP address unless they are sure of what
they are doing.)

There have been many similar posts about the search hijack. In my case
I noticed that my IE6 browser search behaved differently following the
RuneScape Windows Client download from the Internet to play the
Web-based Active X control game. Since then my pc always try to
connnect IP 69.26.170.37 whenever I am on line.

I am not sure if RuneScape is the cause of the problem (it has a trust
certificate to show), but my Zone Alarm Personal Internet Log shows
that if I deny access to programs such as Internet Explorer or Windows
Explorer, the ZA log will show that access to IP 69.26.170.37:80 is
denied too.

My computer had Spywareblaster installed. Scanning using resident
Adaware and Spybot with latest undates produced negative results.
Scanning with Antivirus Avast! (autoupdate) also revealed nothing.

Free online scans provided by Pest Petrol and F-Secure removed some
trojan key loggers, adware and dialers. Further online scan using
Symantec and Yahoo Antispy showed that there is nothing left, but the
problem remained.

The effect of the problem is shown when I use the IE Address bar. For
example, if I type uob and <enter>, I get a web page showing uob.com
with links to other sites (the code appears to be java code). The
address bar will show http://uob/.

Similarly, if I type 69.29.170.37 in the Address Bar, I will get a
bogus web page called Seek2.com, again with links to other sites.
Sometimes a popup message asks me whether I want to set a bogus
http://search.net as my home page. However, if there is a legitimate
address such as dbs, the correct web page will be displayed. The
behavior of the search has been changed since then and I can't get
back the default.

I have try using HijackThis, removing suspicious entries without
success.

CWShredder showed nothing.

Scanning in the safe mode also turned up nothing.

Newsgroups have similar postings on the seek2.com but they are not
much of a help to me.

Using WHOIS traced the IP to unknown.xeex.com. This is sometimes shown
in my ZA internet log.

I have included the IP in my hosts file. But I am not sure whether it
works. In any case I learned that the hosts file can be hijacked too.

I installed Sygate Personal Firewall which can block individual IP.
With ZA deactivated and this IP blocked from all applications, I typed
the IP in the address bar and got the message that "the message cannot
be displayed....", with the status bar showing that I was in Local
Intranet Zone!

If I click on the Search button, it will trigger an attempt to connect
to 69.26.170.37:80 via IE, in addition to Yahoo and MSN. But at least
the Search functions appear to work according to the Advanced tab in
the Internet Options.

And now my Sygate Firewall Packet Log shows that practically every
application that goes on line, and some window services are blocked
trying to connect to 69.26.170.37. Examples are, besides IE, Avast
Antivirus, WinWord, Windows Media Player, Realplayer, MSN Messenger,
Spybot's TeaTimer, svchost.exe, ntoskrnl.exe, lsass.exe, services.exe,
csrss.exe, etc.

By the way, my internet access is through an ADSL Ethernet modem
(Aztech DSL 305E) and a SMC 5 port switch. I wonder whether these can
be exploited? I am using XP Professional SP1 with all the latest
updates (SP2 uninstalled because of compatibility issue).

After struggling to find a solution for over a month, I now find that
my computer also tries to contact 64.15.205.xxx (svchost.exe) for no
apparent reason.

Any comments would be appreciated.

Dealing with Trojans & Hijackware

A. Trojans

1. Download and run Stinger (http://vil.nai.com/vil/stinger/); then...

2. Update your virus definitions, enable Show Hidden Files
(http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2002092715262339)
and then run a full system scan in Safe Mode
(http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406)
with nothing else running in background. Note the files identified and
removed then find the corresponding page for the file at your AV maker's
online support pages (e.g.,
http://securityresponse.symantec.com/avcenter/venc/data/adware.winfavorites.html)
and follow *all* Removal steps, including editing the Registry if directed.

WinXP Only (WinME similar): If this scan finds anything, create a new
Restore Point then:

Disk Cleanup > More options > Delete all but the most recent Restore
Point.

http://inetexplorer.mvps.org/Darnit.htm

Run these tools in the following order with nothing else running in
background:

1. CWShredder v2,0 (Run "Fix", not "Scan)
http://forum.aumha.org/downloads/cwshredder.zip

2. Ad-Aware SE (reconfigure per Post #2 in
http://aumha.org/forum/viewtopic.php?t=5877; fix all found)
http://www.lavasoftusa.com/support/download/

3. Spybot (RTFM; Immunize then Scan; Generally fix everything in red)
http://www.safer-networking.org/en/index.html

Important: You must seek updates for Ad-Aware, Spybot, etc., before each and
every use, even "right out of the box". But even they can't catch
everything, 24/7.

When all else fails...

HijackThis
http://forum.aumha.org/downloads/hijackthis.zip

....is the preferred tool to use. With advice from experts, it will help you
to both identify and remove any hijackware/spyware. Post your log to, e.g.,
http://forums.spywareinfo.com/, http://computercops.biz/forum67.html or
http://forum.aumha.org/viewforum.php?f=30 for expert analysis, **not here.**

Thanks for your response. As mentioned in my earlier post, I have
already spent more than a month doing practically all the *homework*
recommended, except posting the HijackThis log for experts' help.

I think I will do a clean reinstall (from fdisk) and use Firefox for
browser.

BTW, how does showing hidden files help in the antivirus scan. Do you
mean that if hidden files are not shown, they will not be scanned?

You're welcome. Why haven't you posted your HT log yet? Thousands of users
post their logs every day as it's the only way to remove most hijackers
these days.

Formatting and reinstalling Windows will solve the problem in most cases,
yes, but not in all.

While I can respect our (possible) cultural differences, there's very little
of a private nature in a HT log and you can Register at the forums using any
name you want. About the only thing users can find out about you when you
post to a forum is your IP, and then only in some forums.

Compare yours to those posted at, e.g.,
http://forum.aumha.org/viewforum.php?f=30

CrystalBall© says, "If there's something XXX Rated in your log (e.g., R1 -
Startpage - http://sexygirls.[intentional munge]net), your probably should
have HijackThis 'fix' it."

Thankks once again for the link. Will try out the recommended Sysclean later.
