avast web shield has detected a thread infection JS:Redirector-BDP Trj http://im

[raven2967]

hello,

new member here, and would like to say hello to everyone.

am using an old imac with os x version 10.9 and apple's latest operating system.

yesterday doing an internet search i clicked on psychcentral.com and my avast software shield displayed saying infection detected with this information below:

infection JS:Redirector-BDP Trj
URL. http://imgn.psychcentral.com/www/delivery/afr.php? zoneid=6&target=_blank&cb=963

i did a full system scan with avast and it did not show the infection, and the virus vault remained empty, but what i typed above was in the web history activity, so i know i still  have the infection.

i need to also know until this is cleaned and removed from my imac, will this infection redirect me to other web sites unknowingly, and am i at risk?

i am elderly, partially blind, disabled, and on a fixed small income and i am not imac savvy and have no idea how to clean this out of my imac.

 i would greatly appreciate step by step help from avast experts if at all possible, and thank everyone in advance, and hope they have a happy holiday.

avast saved your day and blocked the infection before doing harm to your computer   

and we here know nada about Mac so post in Mac forum section....
