Browsing through this forum today, I noticed many people have a problem with bridge.dll causing various errors in windows. So, instead of responding to every single thread, I thought I might put a solution to this dilemma in one post to streamline things a bit. So here goes.
The two most popular are Ad-aware and Spybot S&D (search and destroy). For help with setting these up refer to: How to Setup Ad-aware & Spybot
Make sure you do a detailed scan with the software and remove as much spyware as you can. This will catch the bridge.dll problem. However, this is a sticky problem and usually won't go away. Even after the scan and removal, the bridge.dll error may still pop up during boot time. If you are still receiving this error, it is due to the fact that a registry key has been added to windows by the spyware that installed itself onto your computer. So now when windows boots up, it is still looking for bridge.dll to run and can't find it because you removed it with your spyware scan!
We can get rid of this pesky error by using notepad and the registry. I'll step you through it.
REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] "RunDLL"=-
Cut and paste the text above in the code box into a notepad file onto your desktop. Unsure how to get to notepad? Go to start, Run, then type 'notepad' and hit return. That will pop up a notepad window that you can cut and paste the above code into. Save it to your desktop...it doesn't matter what you name it. Save the file. Now double click it and it will ask you if you want to add this value to your registry. Accept the change and reboot. Your bridge.dll problem should be history! Good Luck!
happy Spyware hunting!
