Welcome to Short-Media. You have a few problems in your log. Before proceeding with Omegasearch removal, please follow the instructions in this thread to download and run Ad Aware and Spybot on your system. You also appear to have some Cool Web Search variants on your PC, so you will need to download CWShredder from this site and run it on your system. Once you have done all that, run HJT again and post a fresh log for review and we'll get your Omegasearch taken care of.

Dexter...
