so what is the actual problem?you said you clicked on something and your paranoid about doing that but didn't say that anything changed..what changed?
checked yopur proesses for an oddball or is computor lagging in usage on or off internet??
if you notice a change then go to this site .its saved my ass on my other computer with a pup/browser hijacker..wish i had the old link from then..all free programs*
http://www.bleepingcomputer.com/virus-removal/
run through the pup removal guide and browser hijacker guides..best wsite ive ever found...gl
best program ive ever found is malwarebytes-used free to save myself for years and finaly bought it to have real time protection
i use firefox and rarely allow java / I run mse and malwarebytes pro*so far this computor no viruses.
