Recently while browsing a pop-up occurred saying it detected high amounts of suspicious outbound traffic. After looking at the security history I'm not sure if my computer is infected or if the intrusion was blocked.

The attack was resulted from \DEVICE\HARDDISKVOLUME4\PROGRAM FILES (X86)\GOOGLE\CHROME\APPLICATION\CHROME(dot)EXE. To stop being notified for this type of traffic, in the <b>Actions</b> panel, click <b>Stop Notifying Me</b>.
It says IPS Alert Name: System Infected: Trojan.Adclicker Activity 7 but the intrusion was blocked and scans are not picking up anything.
My question is, should I be concerned about this and attempt to remove this via other tools or is this a case of a one-off attempt to attack my PC and be more careful in the future?
