      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.

Browser Hijack ??

9 posts in this topic

I seem to have acquired a browser hijacker yesterday, when I installed a screensaver program. It seemed harmless at first, the screensaver was not what I expected and I uninstalled it. Then today when I went to my homepage (Webshots) I was grabbed and redirected to a blank page with a site title "http://209.50.251.182/vu083003/object-c002.cgi" with a porn popup over it and a security warning on an underlying page about spyware and porn popups with a link to a spyware removal tool to "fix" my "problem". It also activated ZoneAlarm wanting to let Microsoft HTML Application Host access the internet. I said no and checked don't ask again and then ZA asked if ftp.exe could access the internet. Again I said no. I then closed down all open IE windows, noting that my new default homepage seemed to be http://default-homepage-network.com/start.cgi?new-hkcu. I shortened that to http://default-homepage-network.com/ and got to a page telling me that due to problems with their "business model" they were voluntarily ceasing operations at the end of June 2004. I went to Google and checked their cached page for that address and it seems like a straight up spyware firm trying to put on a legit face. Either way, I ran Task Manager and found 2 running processes that were new 0Pwh.exe (in the C:\WINDOWS\prefetch folder) and wowexce.exe (no location given, but I found it later in the registry). These two seem to be the visible cause of the trouble (renaming them stopped some of the activity, but not all.), but I'm not sure if I should delete them and edit them out of the registry or if I should install and run HijackThis to get rid of all traces of the nasties. A Google search for the "cgi" on the end of the address told me it is looking for a "Common Gateway Interface" which seems to be a script file written to open a portal to the internet. Also, the 0Pwh file attempted to access the internet, when I rebooted the system, from an entry in the registry. ZA stopped it, but that was what told me it was something I needed to be careful with. I'm pretty certain that I've identified the problem, I just need to know the best course of action to resolve the issue without any harm to my system. It doesn't appear that I have been locked out of regedit, Internet Options or Control Panel. I have downloaded HijackThis v1.97.0.7 and will install & run it if this cannot be resolved manually.

Please advise.

After considering the issue and learning more about HijackThis, I felt that a scan was in order. I'm fairly certain I have identified the problem and stopped it by renaming files. However, I want to be sure to get everything associated with this incident off my system. The results of a scan this morning, with what I believe are the problem entries highlighted in red, are as follows...

I seem to have resolved the issue. I removed the entries I was certain of, using Hijack This, and then manually removed all files and folders associated with the hijacker, and the screensaver that deliverd it, from Windows after rebooting. Ran Disk Cleanup and then checked the Temporary Internet file for any leftover cookies and found a cab file authrootst.cab that contained a Certificate Trust List file authroot.stl that reinstalled the hijackers web address on my system when I attempted to examine it to see what it was. It did something that was almost too quick to notice. I immediately ran another Hijack This scan and the address was back. I removed it and all has apparently been well for about 24 hours. I'm reposting a new log with entries that I find suspicious highlighted in red. Please advise.

My thanks to all who responded to my request for assistance. :hmmm:

 

I've removed the 2 references to Smartbot.net and believe I have cleaned my system of all traces of this recent hijack. But I can't be certain. :scratchhead:

 

Thanks again for all your help. :thumbsdown:
