Intrusion attempt by local host - query

When ever I use my computer now, within the first 1 - 5 minutes of logging in to my desktop Norton notifies me of "an intrusion attempt by local host was blocked". I would post the screenshot on this thread to save a lot of time describing it but I don't know how to save the screenshot in pdf or txt...

Norton's recommended action is "no action required" but this happens every time I use my computer and is a bit of a concern to me. The IPS alert name is "system infected: adware installer activity 7"

I will copy and paste the network traffic information relating to the attack below (from my security history), sorry if it appears to be a jumbled mess:

Network traffic from <b>d2e24t2jgcnor2.cloudfront.net/secure/check?user_id=21ea01e9-c5a2-477e-87e5-a361f51fd53f&uc=20140905&subid=20140905&source=browsersafeguard-rockettab-spigot&version=1.0.5360.24565&implementation_id=browsersafeguard-rockettab-spigot &block_host=False&reg=False&redirectms=True&ResponseCode=200&ContentType=application/json; charset=UTF-8&Process=firefox&Displaysite=https://www.google.com.au/complete/search?client=hp&hl=en-AU&sugexp=msedr&gs_rn=60&gs_ri=hp&cp=1&gs_id=tv&q=b&xhr=t</b> matches the signature of a known attack.  The attack was resulted from \DEVICE\HARDDISKVOLUME2\PROGRAM FILES (X86)\ROCKETTAB\CLIENT.EXE.  To stop being notified for this type of traffic, in the <b>Actions</b> panel, click <b>Stop Notifying Me</b>. 

Should I be concerned about this or continue to ignore it. I have Norton 360 installed on my PC. 

Kind regards,

Mark
