Ok, sorry about that guys, bit of a noob,

I am running IE as my browser. I tried PC Rescue, Scanspyware, Adaware SE Personal, Xoftspy, and Spybot. All of these were updated prior to running. I ran AVG Free and House Call virus checkers. I used PC Pitstop online tests to see if anything was picked up, nada.

I am using Windows XP Professional, I tried to follow the links that Black Cluster and Phishphreek supplied, it wouldn't load them. I managed to use the task manager to end the process tree of ocuvlbb.exe and that freed my computer up to a normal usage level.

But I still couldn't download anything from the net. I did use a program called Internet download accelerator. I used the shareware version which expired after 30 days. I am wondering if this program has somehow taken over my registry link and is stopping my downloads.

I unistalled it via the add/remove program. I cannot download Hijackthis from my computer so will try and get it from somewhere else.

I hope I have answered everything, I appreciate any help guys.
