      IE 11 copy/paste problem

      It has come to our attention that people using Internet Explorer 11 (IE 11) are having trouble with copy/paste to the forum. If you encounter this problem, using a different browser like Firefox or Chrome seems to get around the problem. We do not know what the problem is, but it seems to be specific to IE 11 and we are hopeful that Microsoft will eventually fix it.

Backdoor.Trojan

3 posts in this topic

Norton AntiVirus tells me I have a virus Backdoor.Trojan but it is unable to access or repair file.

 

I have followed Norton's proceedure for removal with no results. I have scanned with Ad-Aware, SpyBot S&D, and Spy Sweeper, still no results.

 

Your help is appreciated. Here is my HijackThis log:

Hi Redmond,

 

I had the same problem and after 36 hours of work I was on the right track but picked up some important help from this forum and finally fixed it. My sugestions are below however if this works the credit goes to Wapi who was helping ejosh87 a few days ago.

 

The problem seems to have surfaced a few days ago with the relese of Nortons latest virus defs. The Norton help page refered to in the associated virus alert window was no help at all, but the suggested fix below should help (hopefully).

 

Anyway the suggetsed fix is:

 

Overview:

You’ll need to go to the registry kill the key that launches the msik.dll (might be called wina.dll, logojfk.dll or something different). Then change security permissions for system32 files to uncover/control the file, rename the file and finally you will be able to delete it. Then use HijackThis to clean any random BHO’s and also CWShredder and Spybot. Looks like the AppInit_DLLs registry key launches the msik.dll (or whatever your dll is called).

 

 

Fix:

1. Norton or other virus software should have indicated a Backdoor.Trojan virus infection. Note the dll and path.

 

2. Run HijackThis and find the value for the above dll (HKLM\..\Windows NT\CurrentVersion\Windows :AppInit_DLLs=C:\WINDOWS\System32\[msik]????.dll. don't bother fixing at this point it as it will just come back again.

 

3. Go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs (use regedit). Find and remove this key by first renaming the Windows folder Windows2 and then deleting the AppInit_DLL corresponding to your target dll’s name. If you don’t rename it, it will continue to just come back - (you can delete it then press F5 to see it just reload itself).

 

4. After deleting the AppInit_DLL value corresponding to your dll rename the Windows2 folder back to Windows.

 

5. Now to delete the actual msik.dll; go to Start-Settings-Control Panel-Administrative Tools-Local Security Policy-Security Settings-Local Policies-Security Options and change the Recovery Console options (x2 - both of them) to enable from disable.

 

6. Go to the system32 folder and change the file permissions to allow Full Control for Administrators to Modify, Read & Execute, List Folder Contents, Read and Write. Remove all controls from file Creator Owner. If you don’t have a security tab go to folder options in control panel and enable it. If you have XP home edition you might not be able to do this but don’t stress at the above values are usually the default ones anyway.

 

7. Reboot in Safe Mode and the file msik.dll (or whatever it is called) will appear under the system32 folder.

 

8. Rename the file to msik.junk and then delete it

 

9. Empty the Recycle Bin.

 

10.Use AboutBuster, CWShredder and HijackThis to clean up remaining remnants.

 

let me know how you go or if you need and clarifications.

 

Cheers,

Mish
