You don't go to internet properties to empty files. You either use Disk Clean up or do this from within the browsers. Open IE, go to Tools, Browsing History, Settings button. When that opens Click View Files, when that opens go up to Edit, Select All, Then Delete Selected Items on the Left Side will show. Click that and they all should be deleted.
In FireFox, go to Tools, Options. Privacy, Show Cookies, Click the Remove All Cookies.

Or you can do it in one operation;
Download CCleaner and use it to clean temp files. Run it with the default settings. This should empty them. You don't need to be online to empty internet temp files. Install the program, open it up, click the Analyze button, when it is finished then click the Run Cleaner button.



how do i fix the error "Windows host process (Rundll32) has stopped working" when i try to clear temporary files under control -> Internet Options -> Delete cookies and browsing history

i know you said to run the cleaner and i did do that and it cleared the temp files...but i think my original question was why Rundll32 is not working and vista is giving me an error for it

i guess i can re-install IE if that's what's causing the problem and you guys don't see anything wrong with the log....

i'll wait to see if i can fix it w/ anyone's suggestions before re-installing IE


You never updated MBA-M as requested in my previous reply. If you want us to be successful, you need to follow closely the instructions given :).
Please repeat the procedure after updating.

There is no indication at this time that there is a problem with Internet Explorer it self. Leave it alone. Infections are present on the machine and therefore this is the likely reason for the difficulty in removing temp files and the cause of the Host Process Rundll32 problem.

Please continue with the steps given by Crunchie and update MBA-M and run it again. There is NO NEED to reinstall Internet Explorer at this time. If Crunchie or myself later see this would be needed we will certainly tell you to do so. For now please continue with the clean up steps we have given you. Update MBA-M run the Full Scan again, remove items found, Reboot the Computer. Then run a NEW HiJackThis scan and save the log. Post back with both new logs.
