mitchb

Ok checked further and the smurf attack only happens when the PC is put on

10/25/2008 13:18:38 **Smurf** 169.254.255.255->> 169.254.160.85, Type:3, Code:3 (from ATM1 Outbound)

Ive run virus and spyware scanners but none are detecting it, how can i find and delete this?

Browntoa

wait for reluctant to give you more advice

he'll po back soon

Reluctant_spender

I'm starting to run out of ideas - I still have a few more and some last ditch efforts.

1.
Please download ATF Cleaner by Atribune. (This program is for XP and Windows 2000 only)

Double-click

ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.
If you use Firefox browser

Click

Firefox at the top and choose: Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click No at the prompt.
If you use Opera browser

Click

Opera at the top and choose: Select All
Click the Empty Selected button.
NOTE: If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.
For Technical Support, double-click the e-mail address located at the bottom of each menu.

2.
Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:

• Double-click on launch.exe to start the program.
• Cancel any prompts to download the latest CureIt version and click Start.
• At the prompt to "Start scan now", click Ok. Allow the setup.exe/driver to load if asked by any of your security programs.
• The Express scan will automatically begin.
  (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
• If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
• When complete, click Select All, then choose Cure > Move incurable.
  (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)

• Now put a check next to Complete scan to scan all local disks and removable media.
• In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
• Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
• When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
• Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
• In the top menu, click file and choose save report list.
• Save the DrWeb.csv report to your desktop.
• Exit Dr.Web Cureit when done.
• Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
• After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

3.
Please download F-Secure Blacklight (fsbl.exe) and save to your C:\ drive.

• Open a command window by going to Start > Run and typing: cmd
• Copy/paste or type the following in the command window: C:\fsbl.exe /expert
• Hit "Enter" to start the program and then close the cmd box.
• Accept the user agreement and click "Next".
• Click "Scan".
• After the scan is complete, click "Next", then "Exit".
• BlackLight will create a log in C:\ drive named "fsbl-xxxxxxx.log" (the xxxxxxx will be the date and time of the scan).
• The log will have a list of all items found. Do not choose to rename any yet!
  I want to see the log first because legitimate items can also be present...like "wbemtest.exe" and "tcptest.exe.
• Exit Blacklight and post the contents of the log in your next reply.

Okay doen step one - cleard 81.5mbs

Just starting step 2 will post back once thats done.

Thanks again for all your help and advice guys

mitchb

Ok dr web results as below

RegUBP2b-Mitchell.reg;C:\ProgramData\Spybot - Search & Destroy\Snapshots2;Trojan.StartPage.1505;Deleted.

Smurf didnt register on router log at PC startup this time, so hopefully cleared but ill keep an eye on the router log.

Is it worth doing step 3 Reluctant_spender ?

Thanks again for all your help.

Reluctant_spender

It should only take a few minutes - it's up to you?

mitchb

Okay trying to run blacklight but the dos command is saying C:\fsbl.exe /expert isnt recognized as a command or program file.

I have downloaded it to my c drive and when i click on it it would allow a scan, is it different doing it this way?

I suspect is is but thought i should check

Reluctant_spender

Change of plan slightly - either click on the exe file or download it to your desktop and double click it from there
