thanks for pointing me towards this Mike. It referred to a bunch of stuff which I had already seen, but gave me confidence I was on right track. Over the past few days (when time available) I have been watching videos on youTube by Britec09, reading all the stuff connected to his description on youTube and the stuff included in the link you posted.
Couldn't get to work on infected computer until this morning, about 7am. After several attempts and re-boots I almost had it...I felt something was still not right but I was able to see all my files and able to log onto internet. When I did Internet Explorer opened when normally Firefox opens as default browser.
I made it all the way here to this thread on Serif Forums and logged on to post a message when Firefox crashed and things started blinking, just like it did when this all started. So I know I am back to square one. Well, not quite that far back as I have learned a few things.
Whoever is behind this are some very nasty people. My weekend is shot.
