Hi there Cash.
Try Hijackthis without saving it first , click the link and just select run and when the zip file opens try to run
hjt from there. See if you can make a log that way.
And see if you can do a Panda online AV scan here:

And post the log from that aswell.
If
hjt still doesn't work then click
here and download Itty Bitty Process Manager (IBProcMan.zip): ibprocman.
Unzip it to it's own directory and try running it - it will provide a 'taskmanager' like process viewer in which you can stop running processes. Don't stop any yet, just list all that it has so whe can check them and give advice.
Post the list back here please.
