I have this PC in front of me that has been a breeding ground for malware. This PC has been scanned, cleansed and rescanned till I'm blue in the face and this one stupid POS thing named PWS.LDPinchIE just refuses to lay down and die! Here's what I've done so far:

Ran AVG AV free, Kaspersky AV 7.0 and Windows Malicious removal too - removed ALOT of viruses.

Fired up HTJ 2.02, researched and removed all that was deemed evil. Unhid all hidden files, folder and protected system files. Ran Spybot, adaware SE, Spyware Terminator, and Super Antispyware - Removed a ton of crap. All return 100% clean with the exception of Spybot that shows PWS.LDPinchIE and Wild Tangent (They want to keep WT for games).

I've attached my current HTJ log. At this point, I'm afraid to reconnect it to the internet for fear of re-infestation. When Spybot detects PWS.LDPinchIE, its always a regfile. After deleting, it returns on reboot. Thanks for any help you can provide. I can't find anything useful on the net in regards to this thing. Is it a new form of malware?

Hi

That might be false positive.

Please download the Registry Search tool by clicking on the "hard drive" icon halfway down this page:
http://www.billsway.com/vbspage/
Save it to the desktop and run it. If you get an alert from your antivirus about scripting, choose to allow the script to run. Search for RpcApi and click OK. Post the logfile from the tool here for me.

Also do this:

To access the Uninstall Manager you would do the following:

1. Start HijackThis
2. Click on the Config button
3. Click on the Misc Tools button
4. Click on the Open Uninstall Manager button.

You will now be presented with a screen similar to the one below:

http://img.bleepingcomputer.com/tutorials/hijackthis/uninstall-man.gif

5. Click on the Save list... button and specify where you would like to save this file. When you press Save button a notepad will open with the contents of that file. Simply copy and paste the contents of that notepad here on your next reply.

Post:

- registry search results
- uninstall list

Hi

Uninstall via add/remove programs:

Viewpoint Media Player

First we'll need to backup registry:

Start -> Run -> regedit -> ok. Then File -> Export. Give it a name and press Save.

Save text below as fix.reg on Notepad (save it as all files (*.*)) on Desktop

Windows Registry Editor Version 5.00

[-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\RpcApi]

[-HKEY_LOCAL_MACHINE\SYSTEM\ControlSet004\Services\RpcApi]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RpcApi]

It should look like this -> http://users.telenet.be/bluepatchy/miekiemoes/images/reg.gif

Doubleclick fix.reg, press Yes and ok.

(In case you are unsure how to create a reg file, take a look here (http://www.nellie2.co.uk/file.htm#How_to_Make_a_.Reg_File_) with screenshots.)

Reboot.

Do another search for RpcApi and post back results.

No, I don't think so as combofix detects and removes it, too.

Do you want any further research? :)

Hi

Then you're clean!

Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:

You should install Service Pack 2 via Windows Update immediately

After that please install a firewall:

Looking over your log, it seems you don't have any evidence of a third party firewall.

As the term conveys, a firewall is an extra layer of security installed onto computers, which restricts access to systems from the outside world. Firewalls protect against hackers and malicious intruders. I want you to download a free firewall NOW from one of these excellent vendors:

1) ZoneAlarm (http://www.zonelabs.com/store/content/catalog/products/sku_list_za.jsp?dc=12bms&ctry=US&lang=en&lid=nav_za)
2) Agnitum (http://www.agnitum.com/products/outpostfree/download.php)
3) Sunbelt/Kerio (http://www.sunbelt-software.com/Kerio-Download.cfm)
4) Comodo (http://www.personalfirewall.comodo.com/)

If you are using the built-in Windows XP firewall, it is not recommended as it does not block outgoing connections. This means that any malware on your computer is free to "phone home" for more instructions. Simply put, Windows XP contains a mediocre firewall. This firewall is NO replacement for a dedicated software solution. Remember to use only one firewall at the same time.

Disable and Enable System Restore. - If you are using Windows XP then you should disable and re-enable system restore to make sure there are no infected files found in a restore point.

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

Windows XP System Restore Guide (http://www.bleepingcomputer.com/forums/tutorial56.html)

Reenable 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/topic405.html)

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/tutorials/tutorial60.html)

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com (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 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/tutorials/tutorial49.html)

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.

Here are some additional utilities that will enhance your safety

IE/Spyad (http://www.spywarewarrior.com/uiuc/resource.htm) <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
MVPS Hosts file (http://mvps.org/winhelp2002/hosts.htm) <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
Google Toolbar (http://toolbar.google.com/) <= Get the free google toolbar to help stop pop up windows.
[/u]<= Download and install the free version of Winpatrol. a tutorial for this product is located here:
Using Winpatrol to protect your computer from malicious software (http://www.winpatrol.com/features.html)

Stand Up and Be Counted ---> Malware Complaints (http://www.malwarecomplaints.info/index.php) <--- where you can make difference!

The site offers people who have been (or are) victims of malware the opportunity to document their story and, in that way, launch a complaint against the malware and the makers of the malware.

Also, please read this great article by Tony Klein So How Did I Get Infected In First Place (http://castlecops.com/postlite7736-.html)

Happy surfing and stay clean!

This was a friend's PC. I was asked to clean it up since I know more about PCs than her. Good advice nonetheless and I've just finished applying SP2 with all updates. All thats left to do is install a firewall. Would I be correct in assuming that Windows Firewall isn't adequate? I use WF on my own PC, but its also behind a hardware firewall.

Hi

"Would I be correct in assuming that Windows Firewall isn't adequate?"

Yes. Like I posted below:

"If you are using the built-in Windows XP firewall, it is not recommended as it does not block outgoing connections. This means that any malware on your computer is free to "phone home" for more instructions."

"I use WF on my own PC, but its also behind a hardware firewall."

If you are using a hardware firewall, which is properly configured, then it's totally different thing :)
