      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.

Explorer.exe, possible memory leak?

4 posts in this topic

Hi Everyone,

 

I'm running Win XP Pro SP1.

My IE homepage was reset to about:blank yesterday. Additionally, Notepad and Windows Media Player 9 refused to open. I discovered this was possibly due to a CoolWebSearch trojan. I fixed the Notepad and Media Player problems and ran Adaware, Spybot S&D, NAV 2004 scan to remove infected files/registry entries. I think that all traces of malware have been removed, BUT I am experiencing a problem with the Explorer.exe process.

 

At this moment, the explorer.exe process is running at 117MB. It used to run at 20 - 30MB. Additionally, Page File memory after a restart of XP used to run at 160MB. It now runs at 280MB when the PC starts and currently it's 410MB with only 1 Window open!! I tried a system restore, but Windows reports it cannot use any of the restore points.

 

How can I prevent the explorer.exe hogging so much memory, or will I have to format my system to get it back to how it was?

 

Any suggestions/solutions would be much appreciated.

Hi All,

 

It looks like the memory leak prob has been solved.

I was looking for a solution to the problem this afternoon and thought I'd try installing Spywareblaster v3.1. I installed it, but whenever I tried to run the program, I received an error msg:

 

'This program has been damaged, possibly by a bad sector of the hard drive or a virus. Please reinstall it.'

 

I searched on the web for this and found that a number of peeps had the same problem and that it was caused by a CoolWebSearch hijacker. One guy had posted a link to a German website.

 

CWS Removal Site

 

On there you can download a program that supposedly removes the hijacker. Scroll to the bottom of the page and choose 'download'. I downloaded the prog (about 30kb), ran it, it then restarts the PC and now the PC works perfectly. No more about:blank IE home page, Spywareblaster runs correctly and my memory leak has gone.

 

I hope this helps anyone on here who has been tearing their hair out over this.

 

Jon

FANTASTIC!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thankyou very much.

 

I've got 1 or 2 strands of hair left after searching the internet for hours.

As you said, had the SP spyware attack.

removed it using adaware, cwshredder, and then had problems with explorer.exe consuming over a gig of memory when performing a search files.

had thought it was virus, but both a trojan scanner and norton came up blank.

downloaded and ran the program and has worked a treat.

 

ta muchly.
