A computer had been infected with a virus. All traces of the virus I removed but when I went to install the free version of AVG Internet Explorer told me the installation file I downloaded was a virus. I also tried to download the file via Google Chrome.
To stop this from happening a registry edit was required:
Open regedit via the command window.
HKEY_LOCAL_MACHINE> SOFTWARE> Microsoft> Windows> CurrentVersion
and rename “Policies”
After the computer is restarted the download worked as it should
