Hi,

I have this stupid virus, not really sure how I got it and worst, I personally have not such a good grasp on computer removal skills. I'm in Sweden, and so when I read a reply, you will probably be asleep - does time matter if I follow the steps correctly? Also , I run everything on a modem connection, sot he comptuer is slow enouhg as it is. Does this effect anything?

Ok. Here ist he HIJACK THIS description.

Download(right click and select Save file as or Save link as): DelDomains.inf
http://mvps.org/winhelp2002/DelDomains.inf

To use: Close all open browsers
Right-click DelDomains.inf and select: Install

Please download CWShredder but don't run it yet.
http://cwshredder.net/bin/CWSInstall.exe

Download Ad-aware SE from: http://www.majorgeeks.com/download506.html

Install the program and launch it. First, in the main window, look in the bottom right corner and click on Check for updates now and download the latest reference files. Exit Adaware for now.

Make sure that you can view all hidden files. Instructions on how to do this can be found here:

How to see hidden files in Windows (http://www.bleepingcomputer.com/forums/tutorial62.html)

Run Hijackthis again, click scan, and Put a checkmark next to each of these. Then close all other windows--you should only see HijackThis on your Desktop--and click the Fix Checked button.

Hi and thanks,

I did everyting except

1. del domain - pressed install and nothing happened?!
2. cwshredder did not find anything and message was 'cool web search not found on system'
3. manually deleted c:/win/temp files, not folder.
4. in Ad Aware, I deleted all 'critical files' which was about 90. Is this right? How do I know which ones are bad and which ones to keep?
5. Do you know how to log into SAFE MODE intentionally in Win 98? I pressed all buttons and then the option came up...

Here is the new log

You did fine. Your log is clean. Is everything running ok now?

Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
Disable and Enable System Restore. - If you are using Windows ME or XP then you should disable and reenable system restore to make sure there are no infected files found in a restore point left over from what we have just cleaned.

You can find instructions on how to enable and reenable system restore here:

Managing Windows Millenium System Restore (http://www.bleepingcomputer.com/forums/index.php?showtutorial=63)

or

Windows XP System Restore Guide (http://www.bleepingcomputer.com/forums/index.php?showtutorial=56)

Renable system restore with instructions from tutorial above

Make your Internet Explorer more secure - This can be done by following these simple instructions:
From within Internet Explorer click on the Tools menu and then click on Options.
Click once on the Security tab
Click once on the Internet icon so it becomes highlighted.
Click once on the Custom Level button.

Change the Download signed ActiveX controls to Prompt

Change the Download unsigned ActiveX controls to Disable

Change the Initialize and script ActiveX controls not marked as safe to Disable

Change the Installation of desktop items to Prompt

Change the Launching programs and files in an IFRAME to Prompt

Change the Navigate sub-frames across different domains to Prompt

When all these settings have been made, click on the OK button.

If it prompts you as to whether or not you want to save the settings, press the Yes button.

Next press the Apply button and then the OK to exit the Internet Properties page.

Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

See this link for a listing of some online & their stand-alone antivirus programs:

Virus, Spyware, and Malware Protection and Removal Resources (http://www.bleepingcomputer.com/forums/index.php?showtopic=405)

Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

For a tutorial on Firewalls and a listing of some available ones see the link below:

Understanding and Using Firewalls (http://www.bleepingcomputer.com/forums/index.php?showtutorial=60)

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option. This will provide realtime spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an antivirus software.

A tutorial on installing & using this product can be found here:

Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers (http://www.bleepingcomputer.com/forums/index.php?showtutorial=43)

Install Ad-Aware - Install and download Ad-Aware. ou should also scan your computer with program on a regular basis just as you would an antivirus software in conjunction with Spybot.

A tutorial on installing & using this product can be found here:

Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer (http://www.bleepingcomputer.com/forums/index.php?showtutorial=48)

Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

A tutorial on installing & using this product can be found here:

Using SpywareBlaster to protect your computer from Spyware and Malware (http://www.bleepingcomputer.com/forums/index.php?showtutorial=49)

Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.
