FileRepMetagen keeps showing up.

I am running the AVAST Free Antivirus.
Seems I’m getting this message “Avast File System Shield has blocked a threat”. No further action is required.
Object: C:\Program Files (x86).…\iSafeTray.exe. Or this line may read: C:.…\bugreport.exe.
Infection: FileRepMetagen [Malware].
The Process line always reads the same as the Object line.

Then I get the message: “To finish the cleanup process we recommend running a boot time scan”.
I have ran a boot time scan 3 days in a row now.
Other notes: I get these messages every few hours. This started happening about a week ago. When I search programs and files for "isafetray.exe, filerepmetagen or metagen it finds nothing.

So why am I still getting this message and how do I get it to stop?

Sorry. I have 2 images but when I click on the “Insert Image” icon it does not seem to work.
I’ll try again.

sorry still not working.

It looks like you have Yet Another Cleaner (YAC) installed

Ok so I used MBAM and got rid of that Metagen. I have been using the free avast. I’m ready to upgrade. Which avast program do I need to keep stuff like this away? Or do I buy and scan every once in a while with MBAM? Or do I install MBAM and that will keep stuff like this away?
Thank you for directing me on how to rid myself of Metagen.

Thank you.

Pondus,
I did not understand how your reply answered my question.
My question is: Which of these avast programs do I need to keep stuff like Metagen away? Premier, Internet Security, Pro Antivirus or SecureLine VPN?

If anyone else can help it would be appreciated.

Thank you.
