Start-->control panel-->add/remove programs-->uninstall any unwanted toolbars.
aLOT can be removed from the control panel, but it creeps back in and takes over firefox browser. There's also an infection that causes the search engines to go to a redirect page in firefox. Annoying to have an otherwise good browser polluted with aLOT of Spam!
You can turn any toolbar on or off in Internet Explorer from the View menu then Toolbars and untick anything you don't want.
Right back at the beginning of this thread almost two years ago, Joe mentioned HijackThis. Download that from http://www.trendmicro.com and install it then click to scan and carefully go through the list of results,picking out any ALOT related entries and unticking them. Click to remove then restart the computer and all should be well.
