AVG. Although, I haven't subscribed.
AVG is a good antivirus but it has its down side when it comes to detecting this "Potentially Unwanted Programs", please perform a scan with the above tools to make sure your system is clean, and then you can start a thread in the "

TIP: Download files only from trusted sources.
You can drastically reduce the risk of an infection by knowing what and from where you are downloading a file.
As a general rule it’s recommended that you download files from known and reputable sites that have confirmed that the download is malware free.
If you are unsure about the quality of a download, leave the site and research the software you are being asked to install. If it is OK, you can always come back to site and install it. If it is not OK, you will avoid a malware headache.
We recommend that you install a site advisor like
Web of Trust or
Norton Safe Web, which will help you decide if the site is trustworthy or not.
