I was on the internet yesterday and I clicked on a link from google. The link installed a Spyware program called Speed Blaster on my computer so I disconnected immediately and ran Spybot followed by Ad-Aware. (I do have Zone Alarm bu it wasn't running at the time - there's a lesson to be learnt there somewhere). Between the two programs they only found one registry entry and deleted it.
When I searched for files created during that day I found several new files related to Speed Blaster and deleted them all.
Now when I start Windows (98SE) instead of just the programs in the forst list below running, (which I used to get) I now get several more running at the same time (listed further down).
