My computer seems to be back to normal now. Just in case, I thought I’d share (you know me ;-)
I ran TrendMicro’s HijackThis and found two running tasks that looked odd:
O11 - Options group: [INTERNATIONAL] International*
O16 - DPF: {238F6F83-B8B4-11CF-8771-00A024541EE3} - http://a516.g.akamai.net/f/516/25175/7d/runaware.download.akamai.com/25175/citri x/wficat-no-eula.cab
When you google “wficat-no-eula.cab” there doesn’t seem to be a name for this problem, but all of the posts describe the same symptoms I was having. Maybe it is something new, or just a poorly written piece of software. If you look closely at the entry above, a “DPF” is something that Internet Explorer downloads to extend its functionality. Sometimes this is good, and sometimes this is very bad. This would explain why Outlook or Internet Explorer seemed to doom my computer. And why temporarily closing Trend Micro seemed to alleviate the problem (because it was fighting it!).
Here are the instructions that got rid of it. A lot of the files it said to delete, I didn’t actually have (probably because of TrendMicro, thank goodness, I’m a believer now). Basically, I only removed the two things listed above by turning off System Restore under My Computer properties, booting in safe mode, running HijackThis, selecting them, clicking ‘fix’, rebooting and turning back on System Restore. Didn’t really need Killbox after all. Sorry, but I don't remember the forum post that I found this at:
Download the Pocket Killbox programme from HERE (http://www.bleepingcomputer.com/files/killbox.php). Extract it but don`t run it yet.
You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.
Turn off system restore.(XP/ME only) See how here.> http://www.bleepingcomputer.com/forums/tutorial56.html
Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how here.> http://www.bleepingcomputer.com/forums/tutorial61.html
In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how here.> http://www.bleepingcomputer.com/forums/tutorial62.html
Go to add remove programmes in your control panel and uninstall anything to do with(if there).
ComcastToolbar
Close control panel.
Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.
Click on the processes tab and end process for(if there).
uninstall.exe
Close task manager.
Run HJT with no other programmes open(except notepad). Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).
O2 - BHO: (no name) - {64582371-8B2A-A1C6-CE40-0A8E8EB54F78} - C:\WINDOWS\system32\yzwyatl.dll
O2 - BHO: (no name) - {CFE9E8A8-38C0-4EF8-AEC2-5035EFE81030} - (no file)
O2 - BHO: (no name) - {E3215F20-3212-11D6-9F8B-00D0B743919D} - (no file)
O4 - HKLM\..\Run: C:\WINDOWS\system32\rundll32.exe C:\WINDOWS\system32\bhcfvfb.dll,gmzxdjg
O11 - Options group: [INTERNATIONAL] International*
O16 - DPF: {238F6F83-B8B4-11CF-8771-00A024541EE3} - http://a516.g.akamai.net/f/516/25175/7d/runaware.download.akamai.com/25175/citri x/wficat-no-eula.cab
Click on the fix checked button.
Close HJT.
Locate and delete the following bold files and/or directories(if there).
C:\Program Files\ComcastToolbar
Run the killbox.exe file. When it loads type the full path to the file you would like to delete in the field and check the delete file on reboot button. press the Delete File button (looks like a red circle with a white X). It will prompt you to reboot, select no until you have finished inputting the files you want to delete, only then allow it to reboot and hopefully your files will now be deleted. If your computer doesn`t automatically restart, restart it manually.
These are the filepaths you need to enter into killbox.
C:\WINDOWS\system32\bhcfvfb.dll
C:\WINDOWS\system32\yzwyatl.dll
Once your system has rebooted, turn system restore back on and rehide your protected OS files.
Please rename HijackThis.exe to HijackThis1991.exe and post a fresh HJT log.
The reason I want you to rename HijackThis.exe, is because some malware can hide from HijackThis.exe.
