How do I undo the damage from Google Play?

Question

I am not sure which forum to send this to. Please refer me to the correct forum if I cannot be helped here.
I used Google Play, a free cloud where I can store  ITunes songs. I uploaded all 4500 songs over 4 days, but now my IMac is totally messed up!
I never had any problems until this Google Play.
I have an IMac and the operating system is Mac OS X 10.6.8 Snow Leopard. Everything was fine until I started using  "Google Play" and it's Music Manager.
I used "Google Play" and sent (uploaded) all my 4500 ITunes songs to the cloud called Google Play. This took 4 days to upload, because Google Play is a very slow program.  My IMac has been messed up since:
1)  Everything now is super - super  slow.
2) Cannot restart or shut down my iMac computer. Get a message that I must quit Safari first.  But I can't quit safari because the quit safari option in the menu is always grayed out now. So the only way I can shut down or restart is to manually shut off the computer, (via the button in the back of the IMac)  which may harm it. And when I click the button or switch in the back to turn the iMac back on, the problems and the trash dialogue boxes (see #3 below) remain the same.  They do not go away.
3) cannot move anything to the trash. (I am trying to empty the cache in the library to speed up the computer.) I just get dozens of trash dialogue boxes that say "preparing to move to trash" but this goes on forever and nothing is moved to the trash. And I can't get rid of these dialogue boxes that say "preparing to move to trash". There are loads of them and they stay forever, even if I shut down the computer and turn it on again.
Some things I try to move to trash but I get a "copy" dialogue box with the message "Prepare to move to desktop" and that message goes on forever also.
Or it says "Preparing to move to "com.apple.AddressBook" but nothing happens.
(the last one - "com.apple.AddressBook"- is one I had tried to move to the trash).
Shutting off the computer does not help. These trash dialogue boxes are back when I turn on the computer.
4) Trying to speed up computer by going into Utilities (Finder/Go/Utilities) and then clicking on Disk Utility, then McIntosh HD, and then "verify disk". This is supposed to speed up the computer. But when I go into Utilities, the Utilities dialogue box is empty - there is no "Disk Utility" to click on. There is nothing in the dialogue box, except a small spinning circle in the bottom right of the dialogue box that looks like it is trying to do something, but nothing ever happens.
5) Can no longer save documents. If I try to save a new document (click file/save or save as)  the new document does not show up in my documents folder.
Maybe the 4 days of uploading  filled my IMac with all kinds of spyware and that messed things up.  Who knows?
I do have Intego VirusBarrier 6, and have had that and their previous version VirusBarrier 5 for a few years. I ran a full scan yesterday and it found only one new virus besides the 2 I previously had and that were already in quarantine  I put the new one  in quarantine too.
Is there anything I can do?

Answer 1

If I use the Google box, then when I copy the text from Google, it's plain text? Is that correct?
I just used the EditText method and it worked. Thanks
