Re: Trojan Loosky, First Hi-jack-this user.

We can take care of that now.

Download and install CleanUp! (Not Recommended for XP64)[/b].

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

Delete the following files:

C:\WINDOWS\NirCmd.exe
C:\WINDOWS\system32\actskn45.ocx

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

*WARNING* Cleanup deletes EVERYTHING out of temp/temporary folders and does not make backups. If you have any documents or programs that are saved in any C:\Windows\Temporary Folders, please make a backup of these before running CleanUp! or move them to a permanent location.

Open Cleanup! by double-clicking the icon on your desktop (or from the Start > All Programs menu). Set the program up as follows:
*Click "Options..."
*Move the arrow down to "Custom CleanUp!"
*Put a check next to the following:
  • Empty Recycle Bins
  • Delete Cookies
  • Delete Prefetch files
  • Cleanup! All Users
  • Click on the "Temporary Files" and uncheck the box for "Scan drives for file matching" if it's checked.
Click OK
Press the CleanUp! button to start the program.

Reboot/logoff when prompted.

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

Your logs are clean. If there aren't any more problems, please continue with these final instructions and helpful links:

Click Start > Run and copy/paste, or type the following bolded text into the Run box and click OK:

ComboFix /u

***********************************************

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.

SpywareBlaster 3.5.1 to help prevent spyware from installing in the first place. Install & update SpywareBlaster with the latest definitions. After you have updated, click the button - enable protection for all unprotected items.
  • It will block any bad ActiveX from running in Internet Explorer and Firefox if it's listed in their database (which you should update frequently). To view their database and list of restricted sites, launch the program and click on each of the tabs on the main display page.

IESpyAD Zoned Out to block access to malicious websites so you cannot be redirected to them from an infected site or email. This severely impairs attempts to infect your system as it basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.


Update, and scan with your onboard Anti Malware and Anti Virus 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.
