      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.

      PLEASE READ - Reversing upgrade   02/23/2017

      We have found that this new upgrade is somewhat of a disaster.  We are finding lots of glitches in being able to post and administer the forum.  Additionally, there are new costs associated with the upgrade that we simply cannot afford.  As a result, we have decided to reverse course and go back to the previous version of our software.  Since this will involve restoring it from a backup, we will lose posts that have been added since January 30 or possibly even some before that.    If you started a topic during that time, we urge you to make backups of your posts and you will need to start the topics over again after the change.  You can simply paste the copies of your posts that you created at that point.    If you joined the forum this month, you will need to re-register since your membership will be lost along with the posts.  Since you have a concealed password, we cannot simply restore your membership for you.   We are going to backup as much as we can so that it will reduce inconvenience for our members.  Unfortunately we cannot back everything up since much will be incompatible with the old version of our software.  We apologize for the confusion and regret the need to do this even though it is not viable to continue with this version of the software.   We plan to begin the process tomorrow evening and, if it goes smoothly, we shouldn't be offline for very long.  However, since we have not done this before, we are not sure how smoothly it will go.  We ask your patience as we proceed.   EDIT: I have asked our hosting service to do the restore at 9 PM Central time and it looks like it will go forward at that time.  Please prepare whatever you need to prepare so that we can restore your topics when the forum is stable again.

Need "Backdoor.Trojan" help please

7 posts in this topic

Hello everyone ... This is my first post

 

I am running Windows XP with IE 6.0 (with most current updates)

 

I have a virus:

Virus Name: Backdoor.Trojan

Object Name: C:\WINDOWS\System32\resc.dll

 

I continue to get the Norton Virus Alert notification in the center of my screen. I will need to click it's OK buttom many many times to remove the Alert notification. Then it just re-appears as soon as I start any other program.

 

1. A Norton anti-virus scan will not detect any virus on my computer (with the most current update)

 

2. I edited HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT \CurrentVersion\Windows\AppInit_DLLs in the registry. The file C:\WINDOWS\System32\resc.dll was deleted by myself. The file has not returned in the registry, but it did not fix the problem. There are no other .dll files in this section of the registry.

 

3. AdAware 6.0, SpyBot, SpywareBlaster, and CWShredder shows nothing wrong, and has not fixed this problem.

 

What can I do now short of reformatting the C drive?

 

Thanks for any help,

RDL

Start your computer in safe mood (press F5 or F8 when lights flash durning boot)

 

Then look for

C:\WINDOWS\System32\resc.dll

 

Delete that file

 

Go to HJT and fix these:

needenalife ....

 

You, my friend are a GENIUS!

 

I did exactly what you said ... I am not getting the red Norton Virus Alert on the center of my screen anymore ...... GOODBYE BACKDOOR TROJAN !

 

Well, I just hope it don't re-appear, but I think we are in luck. It usually comes back almost instantly as soon as I open up a new program to even include MS Word .... Anyway, I will keep my figers crossed.

 

Last question: Everything seems to be working OK. When I deleted those files you told me to do on the HJT scan, it put a Backup Copy of them (all 7 of them) in my Program Files. Can I just delete them now?

 

Thanks again,

RDL

 

Oh Ya, here is my new scan:
