Avast detects Spore game files as threat?

Hi,

Just today, after a scheduled full system scan, Avast detected 2 files relating to Spore and Darkspore, as threats.
(Spore and Darkspore are Computer Games and I have bought the CD for them and have not pirated them)
I have installed these games years ago and Avast has done many scans before with them installed and have not found problems with them so I am hoping it is just a false positive, but its strange how its never detected them as threats before? Is it possible they could of got infected?
Anyway, here is what the Avast Scan Log said:

File Name: C:\Users\user\Downloads\DarksporeSetup.exe Severity: High Status: Threat:Win32:FakeAV-EZj [Trj]

File Name: C:\Program Files\Electronic Arts\SPORE\Support\SPORE™_code.exe Severity: High Status: Threat:Win32:FakeAV-EZj [Trj]

For now, I have moved them to the Virus Chest, but I would like to know if this is a False Positive or an infection…

I have done full scans with Malwarebytes and SUPERAntiSpyware and both dont detected anything.

I have Windows Vista 32-bit with Avast Free Antivirus V 8.0.1497.

Thank you.

If you want to be sure if these are false positives upload the 2 files to virustotal.com and post the link to your next reply.

You can report the files as false positive by right clicking on them and choose send to virus lab.

Then choose false positive there and descripe the problem.
