how do you know you have a virus if norton does not detect it?
if norton or any antivirus program installed on your computer is kept up to date then it should pick up a virus as soon as you go to open the folder containing it or hover your mouse over the .exe for example.
so long as you are up to date and scan regularly then i dont think its a virus. what is the problem you are having with adobe please (im guessing reader or photoshop?) and why do you think you have a virus?
in the mean time (you probally know this) you know spyware can cause havoc and most of it will not be detected by any up to date antivirus products. maybe download adaware and spybot and install, update and run them both. delete anything they find. click here click here then install spywareblaser and update it click here and 'enable all protection' cant hurt.
not sure sorry.
