Plain and simple, NO!
Well, here is the thing you didn't get the free version. And you say that you can't un-install it then is there a possibility that you downlaoded something other then the software, like spyware or other things. I would recommend that you go here.
Then I would also recommend that download, Spyware S&D. Just google that one, and maybe the free version of Adware.
One word of advice don't download any software off a torrent unless you know exactly where it is coming from.
Cheers!
Just making sure I understand this; and if you undo the system restore, you will get spyware and adware again assuming that had spyware and adware before the system restore?
I downloaded Spyware S&D (you mean Spybot?) before and it gave me too much pop windows if I allow any actions or not. I don't have all day to click and wait for it to go away. How do you use Spyware S&D to your advantage?
Last but not least, what kind of protection does AVG free edition give? Thanks for all the advice. I really appreciate the help.
