Re: Viruses and Trojans, Oh My!

One more file left (this is why we run online scans as well. )

Please ensure Hidden files and folders are viewable:

Go to My Computer->Tools->Folder Options->View tab:
* Under the Hidden files and folders heading:
* select Show hidden files and folders.
* Uncheck Hide protected operating system files (recommended) option.
*Also, make sure there is no checkmark beside Hide file extensions for known file types.
* Click OK.

--------------------------------------------------------------------

Using 'My Computer', navigate to and delete the following File

C:\WINNT\system32\cdcuscnb.dll


--------------------------------------------------------------------

You have a lot of undesirable cookis in FireFox, Netscape and IE. Run AVG A-S--it should take care of those for you.

If not, clear them yourself via each browsers' Tools>Internet Options


You're good to go. If there aren't any more problems, please continue with these final instructions and helpful links:

Reset hidden/system files and folders

===============
Click Start.
* Open My Computer.
* Select the Tools menu and click Folder Options.
* Select the View tab.
* Deselect the Show hidden files and folders option.
* Select the Hide file extensions for known types option.
* Select the Hide protected operating system files option.
Click Yes to confirm.
Click OK.

Ensure Windows Auto Update is Enabled
*Go to Start>Run - type wuaucpl.cpl
*Tick on the checkbox - "Automatically download the updates, and install them on the schedule that I specify".
Click on "OK".

To help protect your computer in the future I recommend that you get the following free programs if you do not already have them:

McAfee Site Advisor--free version. The folks there check out websites and based on their findings, rate it as Safe, Unknown, Caution, or Bad.

IE-SPYAD.EXE to block access to malicious websites so you cannot be redirected to them from an infected site or email. IE/Spyad places more than 4000 dubious websites and domains in the IE Restricted list. This severely impairs 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. This is a self-extracting .ZIP file, save it to your desktop. Once downloaded, double-click on it to extract the files inside (default dir is C:\IE-SPYAD)
  • Now navigate to C:\ie-spyad. Double click to open it.
  • From within the folder, double-click install.bat
  • Select Option #2 - Install the new IE-SPYAD list, by typing 2
  • Then return to the main menu.
  • Select option #4 - Add the old porn sites domain, by typing 4

Update all these programs regularly. Without regular updates you will not be protected when new malicious programs are released.

In light of your recent issue, I'm sure you'd like to avoid any future infections. Please take a look at these well written articles:

PC Safety and Security--What Do I Need?

HOW DID I GET INFECTED IN THE FIRST PLACE? by Tony Klein
THE ANTI-SPYWARE TUTORIAL
MAKING INTERNET EXPLORER SAFER
Understanding and Using Firewalls

**Be very wary with any security software that is advertised in popups or in other ways. They are not only usually of no use, but often have malware in them.

-----------------------------------------------------

Follow the list above and the potential for infection will reduce dramatically.
