Experimental HTML aside molokaiiangirl, you need to do a couple of the usual things first.
First download and run fully updated versions of Spybot S&D and Ad-aware6.
That should take care of DW.EXE.
Next, do a couple of online virus scans - Trend Micros - Housecall and Pandas Active Scan.
While your eating beef and going mental, do a TrojanScan as well.
After that, head to the windows update site and make sure you have Service Pack 2 for IE 5.5.
And while your there, get every other security patch you should have.
THEN, repair IE 5.5.
Click Start >> point to Settings >> click Control Panel >> and then double-click Add/Remove Programs >> On the Install/Uninstall tab >> click Microsoft Internet Explorer 5 >> click Add/Remove >> click Repair the current installation of Internet Explorer >> and then click OK.
Then, as it's already been mentioned elsewhere, download and run SpywareBlaster and keep that updated.
If your still not in good shape after that, download and run HijackThis and post the log file on this thread.
Sure there's something I've missed, but we'll blame that on the slightly acidic red coloured water ;)
