Whenever I make a full system scan on Norton Antivirus, I get a message said "Adware.Lop detected by Auto-Protect, Status: Restart Required, Recommended Action: You must restart your computer." After I restart my laptop and I get onto the interne, I keep getting the Symantec Home Page Assistance (http://securityresponse.symantec.com/avcenter/fix_homepage.jsp) as my home page instead of Yahoo as my real home page. I keep following the instructions again and again, and still can't get rid of Adware.Lop from my laptop.
Please tell how to get rid of Adware.Lop permanently so I don't have to deal with it anymore and Yahoo will be my permanent home page.
