Hello,
I will try to help you.
As for your Compaq error... click Start/Run/type in msconfig and press enter and uncheck Compaq Connections, click apply then ok and reboot.
See if that stops that error.
Then do these scans please:
Lets see what some virus scans can uncover and we will go from there.
Get the stinger here:

Download it to another computer if need be, and bring it to the affected computer on floppy disk.
It will kill the top 53 virus files if any are found there
then,
Internet Explorer required
Run these two online virus scanners (Panda Activescan) following these instructions below:

Internet Explorer required
Also this excellent(BitDefender) scanner:

These scans will take more than an hour to complete, so make sure you have time to let them run thru.
Save the Panda scan log and the BitDefender log and post them back here please with a new Hijackthis log.
Thanks.
