Panda Activescan Installation corrupted my computer?

Ok so i got this bad spyaxe spyware stuff and then i got rid of most of it.  then i did a panda activescan and it found a couple of dialers but it couldnt delete them because it only deletes viruses and trojans and you need to have the full version to get rid of it.  anyways...i downloaded the free 30 day trial of panda titanium antivirus and i installed it and stuff and it said i need to restart my computer to finish installation so i did that and upon rebooting my computer froze.  it shows my desktop and icons but on my taskbar only a couple items pop up and then everything freezes.  i cant click on start or anything.  i thought maybe it was finishing installation but it went on and on being frozen for about 20 minutes.  so i restarted using the power button on my computer and it did the same thing...this time for an hour.  i tried rebooting about 5 times and always the same thing. 

...and let me just say yes my computer was working fine before i installed the panda trial.

 

Please help!!
