Your antivirus is giving a "false positive". This is a direct result of a faulty definitions file. Disable it (completely) while you download and install. And it wouldn't hurt to look into a better A/V program. Eventually this one will delete something you really need because their developers can't or won't keep up with the rest of the computing world.
Thanks for the reply. I did disable my AV program. Iam using Avast.
I did disable my AV program.
And were you able to download the installer?
If not, it may be malware preventing the download.
