So I was browsing around the internet to reinstall Gimp. I went to a website to where I had thought to have downloaded it. While it was halfway through the download, my Norton Security Suit went off and told me that it blocked the Trojan named "dns.exe(Trojan.Dropper)". While I thought this was the only problem on my computer that it detected, when I was browsing my DA I noticed that some text was underlined in red. When I hover above the text it showed these two malicious sites. (IM sorry that I don't know there names. But I did delete them via Programs and Features, although one of them did add something else to my computer in exchange for itself to be deleted). After that, I couldn't figure out how to delete it or add it to the quarantine section of my security suit. So please can you tell me how to delete this program and if it can still cause harm to my computer even if it is blocked?
Sorry if this was posted to the wrong fourm. I apologize.
