Answer 2

The link http://quatangtraitim.us.tf/ is the website that probably installed "Quantangtraitim" through a weakness in your I.E. browser. I think it may have originated from Vietnam or China.

A good anti virus program should have blocked it. The antivirus program Kaspersky does block this website because it contains a virus or other nasties.

You can download the Kapersky evaluation edition and run a full system scan to fix the problem.

http://www.kaspersky.com

Also, Microsoft provides a free service that may help.

"Windows Live OneCare safety scanner is a free service designed to help ensure the health of your PC.

Check for and remove viruses
Get rid of junk on your hard disk
Improve your PC's performance"

http://safety.live.com/site/en-US/default.htm?s_cid=msep

Lastly...
McAfee SiteAdvisor is a web site that allows you to “Look up a site report:" to check if a web site is dangerous to use. You may want to use this site before you visit questionable web sites.

Good Luck

Answer 3

Use another antivirus and see what happens before you do anything especially use antiviruses like avast whereby they can scan the system windows is open.

If that doesn't do format the HDD and install a new windows but make you make a backup of the documents/files/info you treasure. Godd luck.

Answer 4

Trojan Removal Procedure.

Removing infections from your computer is never as easy as aquiring them. Malware infections are not meant to be removed so it takes TIME and PATIENCE to get rid of them. If you do not have T & P then you can always do a Reformat.

Malware is a general word for all form of Viruses, Spyware etc. This procedure works for all Malware. Replace the Ewido program with the appropriate program.

You might be unable to access the Internet after removing the Malware so you will need to run LSPfix or Winsockxpfix (as appropriate). Download one and save to desktop, run it later.

LSPfix: all Windows OS except 95.

http://www.cexx.org/lspfix.htm

Winsock XP Fix: Windows XP only.

Download and Update Ewido (now called the AVG Antispyware):

http://www.ewido.net/en/download/


-- If you have problems updating see here:

http://www.ewido.net/en/download/updates/

Once the updates are installed do the following:



Let's get cleaning

Part 1

• Temporarily show hidden files.

For Windows XP:

1.
Click Start, and then click Control Panel.

2.
Click Appearance and Themes, and then click Folder Options.

3.
On the View tab, under Hidden files and folders, click "Show hidden files and folders", and clear(uncheck) the "Hide protected operating system files" check box.



For older systems:

1.
Double-click My Computer, click View, and then click Folder Options.

2.
On the View tab, under "Hidden files and folders", click "Show hidden files and folders", and clear (uncheck) the "Hide protected operating system files" check box.


IMPORTANT: Files are hidden by Windows for a very good reason. It is not wise to experiment with these files. Unfortunately, to successfully remove modern spyware we must turn this protection off temporarily. Please turn the protection back on when you have finished cleaning your system.


Empty your Internet Explorer cache and your other temporary file folders:

1.
On the Internet Explorer Tools menu, click Internet Options.

2.
On the General tab, in the Temporary Internet Files section, click the Delete Files button. This will delete all the files that are currently stored in your cache.

3.
Select the Delete all offline content check box in the confirmation dialogue box that appears, click OK.

4.
Click OK again.

Restart in Safe Mode:

To do this you need to hold down or repeatedly tap the F8 key while the computer is booting (when the computer is displaying a black screen with white text). When the boot menu appears, use your keyboard arrows to select "Safe Mode."

Safe Mode can look quite ugly. The color may look bad, and all of your desktop icons will be very large. This is normal.



Start Scan and let Ewido scan the PC


When the scan and removal are completed REBOOT COMPUTER. This will restart you in normal mode.

If you are unable to access the Internet after removing Malware you will need to run LSPfix or Winsockxpfix (as appropriate).


If you are using Windows XP Service Pack 2 (SP2) and are unable to access the Internet after removing Malware, there is a command that may fix the problem, removing the need to run Winsockxpfix. It works by resetting the winsock catalogue. Click on Start, then Run and type CMD in the dialogue box that appears. Click OK. Type "netsh winsock reset" (no quotes)into the DOS window that appears.


The last steps

If you are running Windows XP or Windows ME, and your computer has been successfully cleaned of Malware, there is one more thing that needs to be done.

Delete any old restore points and then create a new restore one. The old ones may, of course, be infected with the Malware and cannot be used.

First, start and then stop the Restore Service. This is done differently depending on what operating system you are running.

Windows XP:

1.
Click Start, and then click Control Panel.

2.
Click Performance and Maintenance, click System, and then click on the System Restore tab.

3.
Select the Turn Off System Restore check box, click Apply, then restart your computer.

4.
Return to the System Restore Tab and turn System Restore back on.


Windows ME:

1.
Click Start, click Control Panel, click System.

2.
Click Performance, click File System, and then click Troubleshooting.

3.
Enable the option Disable System Restore, click Apply then restart your computer.

4.
Return to the Troubleshooting tab and turn System Restore back on.


To set a manual restore point complete the following steps:

1.
Click the Start button.

2.
Point to Programs, then navigate to Accessories, then System Tools, then click System Restore.

3.
Choose Create a restore point, and then click Next.

4.
In the Restore point description box, type a name for your restore point, and then click Next.

5.
Click OK.
