Greetings to all.

 

Initially IE9 was not responding as quickly as it used to. I found that Web of Trust was causing it to hang so I uninstalled it. But was still experiencing some issues with slow response. So I downloaded and ran Microsoft MrFixit utility for IE Performance. The tool reported that it fixed Data Execution Prevention and recommended Security Settings due to being disabled. I have run this utility on a few other occasions due to IE9 being sluggish and get the same "fix". Don't know if this is normal but doesn't seem right and I am not an IT Pro by any stretch of the imagination.

 

Read some tutorials and have done the following:

 

1) Changed Data Execution Prevention settings to turn on DEP for all services except those I select.

 

2) Run machine with very few Add-ons

 

3) Delete browsing history routinely and clear cache

 

I'm running Win 7x64 SP-1

 

Would like to know what is disabling DEP and recommended Security Settings. Tried to get answers from Microsoft Answer Forum and

not been successful. So I will pose the question to my fellow members.

 

Thanks for any help and advice,

I know it's probably not what you want to hear, but try another browser. IE is notorious for it's problems, security issues and bugs and every new update is just another reason for it to run slower.

 

If you do install another browser remove IE completely from the installed programs list as well as removing it from windows features, then block updates for it and clear all the temps etc...

 

As to another script disabling DEP, that is news to me, and it seems unlikely that your security services disable automatically without some sort of malware being involved.

Thanks TsVk for your observations. I've considered utilizing another browser such as Firefox. Maybe might give Chrome a whirl as well. So use to IE9 that I just hate to give up on it because it contains features I like.

 

As for the DEP issue it will remain a mystery I guess due to no solution. And Security Settings?? Your guess is as good as mine. Don't know what causes them to be set to less  than recommended levels.

 

I have run various malware programs and all were negative. Have run AdwCleaner as well. I'm sure a fix for this will be forthcoming as surely there are others that are experiencing this as well.

just checking, you do start in safe mode with networking then run rkill or roguekiller before attempting to use other removal tools?

 

this is generally key to removing stubborn viruses/trojans with tools.

Yes, I ran both RKill and RogueKiller in Safe Mode with Networking prior to running MBAM. MSE is my stand-alone and I utilize SAS as well.

Please...do not suggest specialized malware tools such as RogueKiller to members in this forum (Win 7 issues).  BC has two forums for dealing with malware issues and we prefer that any situation headed in that direction...be handled in the appropriate malwaare forum.

 

If the issue is not related to O/S problems...then the topic needs to be moved to the more appropriate BC forum for advice/suggestions.

I know your pain Sikntired... Continuously dealing with people who do this to their machines.

 

You might want to report your own post and get it moved over the malware forum, there's some heavy hitters there, might be able to help.

@Hamluis, Sorry didn't mean to post in wrong forum as I thought my issue was an OS problem after running malware scans. :(

@boopme. Thanks for responding. I know how many need assistance and with that in mind I went ahead and did a re-installation. I want to take this opportunity to thank all of you who assist as I know you give of your time and expertise. :)

Thanks for the kind words ... In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned, repaired or trusted especially if you are dealing with rootkit components that can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. In some instances an infection may leave so many remnants behind that security tools cannot find them and your system cannot be completely cleaned, repaired or trusted. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore with a vendor-specific Recovery Disk or Recovery Partition removes everything and is the safest action

I'll just post this .... You can back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them. Other types of malware may even disguise itself by hiding a file extension or adding to the existing extension as shown here (click Figure 1 to enlarge) so be sure you look closely at the full file name. If you cannot see the file extension, you may need to reconfigure Windows to show file name extensions. Then make sure you scan the backed up data with your anti-virus prior to to copying it back to your hard drive.

If your CD/DVD drive is unusable, another word of caution if you are considering backing up to an external usb hard drive as your only alternative. External drives are more susceptible to infection and can become compromised in the process of backing up data. I'm not saying you should not try using such devices but I want to make you aware of all your options and associated risks so you can make an informed decision if its worth that risk.
How and Where to backup your files in XP or Vista
How to Backup and Restore in Windows 7
How to use Ubuntu Live CD to Backup Files from your dead Windows Computer

Again, do not back up any files with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.

If you need additional assistance with reformatting or partitioning, you can start a new topic in the appropriate Windows Operating System Subforum.

@boopme

 

Thank you so much for the advice. I have no intention of backing up any executable files and will reconfigure Windows to show all file extensions.

 

Best Regards.................
