error message about iexplorer

The last few days I have been getting this message.. The instruction at "0x6600accc" referenced memory at "0x6600accc." The memory could not be "read". Click of to terminate the program. Does anybody know what is going on. I have a Dell computer, a few years old with an 80GB hard drive and 512MB of memory. I have plently of space left, so help please.

 

Do you have Yahoo Toolbar installed? Seems to be the culprit from what I've read. Also bad RAM or malware are possibe causes. Three quotes are:
"turn your tabs off on yahoo toolbar and the problem will go away"
"I have run into odd issues with the Yahoo toolbar as well. When I see it on computers, I just remove it."
"Did this show up after an update to Yahoo tool bar? You can try system restore to an earlier date and this could correct this problem."

Do you Yahoo?
