i have never before had a vitus on my pc. but now malwarebytes says that there is two trojans on my pc that are in c:/program files/AVAST Software/avast/setup/Instup.dll and in c:/Program Files/AVAST Software/Avast/setup/instup_ais-8c5.vpx its saying that they both are Trojan.Agent.UPX are they realy trojans or just some sort of bug with the malwarebytes.
