TR/Trash.Gen?

So, my avira suddenly popped up and detected
mbamservice.exe
mbam.exe
chrome.exe
chrome.exe
rundll32.exe
AcroRd32.exe
IMF.exe
netsession_win.exe
Avira.OE.Systray.exe
Explore.EXE
svchost.exe
Avira.OE.ServiceHost.exe
WLIDSVC.EXE
StarWindServiceAE.exe
SkypeC2CAutoUpdateSvc.exe
svchost.exe
svchost.exe
svchost.exe
spoolsv.exe
services.exe
avguard.exe

as TR/Trash.Gen
I'm actually not sure whether to quarantine it or not, since they do not appear to be suspicious, and I heard Avira sometimes get False Positive results,
My Malwarebytes Anti-Malware did not detect any TR/Trash.gen though.
I'm using windows 7,
