HI
I had a whole lot of spyware in my Toshiba laptop running
XP Home SP1. I ran Adaware and removed all the files and
entries. But they were back the moment I connected to
the net again. The file bridge.dll was manually removed.
XP had not been updated for a while. Hence I decided to
update but IE couldnt read from the site. Immediately
gets hijacked to some popups. Hence thought I will load
the SP2 which I had on CD. That made no difference, so I
uninstalled SP2.
There is no antivirus on the system. Tried to install
Grisoft AVG antivirus. Setup stops with the message File
not found Shell.dll. But this file is actually present.
What is my way out of this mess? Formatting has to be my
last resort.
Thanks for any help please.
Thanks
Ramesh
Ramesh,
AdAware isn't the only tool for finding and removing adware / spyware. In some
cases, it isn't the best tool either. Some spyware hides itself so thoroughly
you need HijackThis and expert advice. Fortunately, all these tools are free.
Start by downloading each of the following additional free tools:
CWShredder <
http://www.majorgeeks.com/download4086.html>
CoolWWWSearch.SmartSearch (v1/v2) MiniRemoval
<
http://www.majorgeeks.com/download4113.html>
HijackThis <
http://www.majorgeeks.com/download.php?det=3155>
LSP-Fix and WinsockLSPFix <
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. Spybot S&D has an install routine - run it. 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
CoolWWWSearch.SmartSearchMiniRemoval, then CWShredder. Have the latter fix all
problems found.
Next, run AdAware again. First update it ("Check for updates now"), configure
for full scan (<
http://www.lavahelp.com/howto/fullscan/>), 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 other
layers regularly, look for things that don't belong, and take action when
necessary.
Cheers,
Chuck
