False Positive?

Today Avast moved this to the virus chest:

tier0_s.dll

It was in the original location

C:\Program Files (x86)\Steam

Can I go ahead and restore this from the chest or is it really a virus?

yes FP… lots of steam posts all over the forum about this today

is your avast updated?..do manual update
right click the file in chest and scan again… still detected?

It says no virus so I guess I’m good, thanks for the help!

when you restore a copy remain in chest…this you can delete when you feel all is ok
