My PC is infected with the coolwebsearch bug. I am running Windows XP, and my antivirus programme is McAfee.

Every time I open a web page i am automatically redirected to other web pages and it is driving me nuts :thumbsup:

Whe I run the Virus Scan McAfee, these are the results I got:

Detection Type: Potentially Unwanted Program
Detection Name: Adware-CoolWebSearch
Status: Detected
Items: Registry
Registry Key: HKLM\system\currentcontrolset\enum\root\LEGACY_ZESOFT

When I click the "remove" button, this is the message that I get:

Cannot Completely Remove This Programme

McAfee has attempted to disable this program, but some parts of it cannot be removed. In most cases, the program will no longer run. If you restart and rescan your computer and the same program is detected again, you can send it to the McAfee Avert Labs for analysis. Samples must be sent to spyware_research@avertlabs.com (subject line:MAS Content) in a .ZIP file. The .ZIP file must be no more than 3MB, cantain no more than 30 files and be password protected using "Infected" without quotation marks.

I have tried CWShredder and Ad-Aware with No success.

Other Than reformatting the Hard drive I have run out of ideas

Can anyone help

Thanks

Since McAfee is notorious for interfering with other programs removing malware it cannot let's try a scan and fix from safe mode with ATFCleaner and SAS

For newer nasty infections I usually have to uninstall McAfee, I try to switch my clients to better software like Avira

No. Try not. Do... or do not. There is no try.

Whatevver SAS did seems to have sorted the problem but will try IE7 later to double check.

However I am getting a Run DLL error message C\Windows\system32\Buhiwuna.dll. oe start up. Noticed this was one of the files quarantined by SAS so I am assuming I shuold not restore this to my system? Is thia right

Thanks

See if you can download and install MBAM, update it, then disconnect from the internet, disable McAfee and run a scan with MBAM

That error means you still have a registry entry calling for the malware

Don't ever expect one run with one program to clear or clean your computer

Your MBAM log indicates some files will be deleted on reboot. If MBAM encounters a file that is difficult to remove, you need to restart the computer so the malware can be fully removed. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. If you have not rebooted, make sure you do this. When done, rescan again with MBAM and check all items found for removal. Then click the Logs tab and copy/paste the contents of the new report in your next reply. If you did reboot, then rescan again anyway and post a new log.

Will run another scan but I have had no problems since I ran MBAM on Saturday. There are no Run DLL errors anymore thie Internet is working fine with no redirections at all and Auto Updates is not being disabled on reboot. So fingers crossed i think the Trojan has been removed

I will post the log as soon as i have run MBAM again just to be sure

Ok.

Then if there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.

You're welcome.

Tips to protect yourself against malware and reduce the potential for re-infection:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".
• "Use Task Manager to close pop-up messages to safely exit malware attacks"

• Avoid gaming sites, underground web pages, pirated software, crack sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
