You should have kept Norton & dumped Limevirus.
Limewire is probably one of the absolute worse things that can be put on a computer.
In the last several years virtually every computer I have removed viruses from had 1 thing in common, "Limewire" .
Try doing full virus & malware scans.
AVG is good [I'm nit just saying that because it's what I use] .
If you can get Malwarebytes downloaded you might want to install it & do a scan, then fix [remove] what it finds.http://download.cnet.com/Malwarebytes-Anti...4-10804572.html
Once you do that go to My Computer
Right click the C drive
on the menu click Properties
When the box opens click on the Tools tab
Where it says Error Checking click Check now
When the3 box opens put checkmarks in both boxes under Check disk options
You will get a message, "Can't run now, yadda,yadda, next startup
Click Tes or OK
Restart the unit & be patient while it does it's thing
Let it start to the desktop on it's own.
