surfsidekick... please help

im not the smartest computer person around… so bare with me. My computer has been shutting off once or twice a day and when i log back on avast has found a trojan in the windows system folder ssk3.exe which when i looked it up on google said it was surfsidekick, its adware and a trojan dropper, i do not know what i need to do to get rid of it though… it keeps coming back. Feel free to email me at caliborn1983@yahoo.com

Hi and welcome,
can you move/ delete it? if not run a boot time scan and that will allow you to.
good luck
