My system was terribly slow and I was constantly receiving gooletoobar1.dll errors. I noticed an immediate improvement when I removed it. Thanks for your help.
I'm thinking it may be used for the Google updater service. I disabled this add-on in hopes of preventing Google from updating my toolbar to any updated toolbar versions that I do not want. I've been battling the Google updater for weeks trying to keep it from updating from v4 to v5. V5 sucks and Google doesn't care if you don't want it or not, they will force it on you anyway.
It doesn't work well with Beta Internet Explorer 8. If anyone knows how to fix it without disabling it, please let me know.
It's completly safe, don't worry!
it's spyware, remove this garbage that slows down your system
did not install google toolbar and do not want it, and it refuses to uninstall

A very useful tool. During install, privacy implications are clearly documented and turned off by default. This is the only good toolbar I have seen.

Best practices for resolving googletoolbar1 issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active googletoolbar1 process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the googletoolbar1.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
