I'm using the Internet Security version of Avast.
I took a risk on downloading some software and got hijacked by something called Vosteran. So, I went out to the web to see how to get rid of it and ended up downloading a security program called Spy Hunter (SH). SH scanned my computer and, besides Vosteran, found all kinds of spyware cookies and such. Of course, in order to clean this up I have to purchase their full program version, which I would rather not do. Will Avast take care of these things for me? Vosteran is new today, but the other spyware stuff SH found has been there awhile, so Avast hasn't been taking care of it so far.
