how to fix problem

This file did not delete/uninstall when I uninstalled AOL from my computer. My PC actually worked great until I downloaded AOL 9.0 SE (which came with 2 trojans!). So, after cleaning up my computer and uninstalling AOL--all versions, I am still left with stranling AOL file such as this one. My computer does not work with the high (great) performance now; albeit the cleanup is getting my PC back to great performance. I would want AOL or any product to remove ALL the product's files upon uninstall. Just my opinion

Dell Crash Analysis Tool named it. AOL sent me here. Hum, if it's really their file, why couldn't they help me work it out?
