I am using GoogleChrome... I deleted all items previously mentioned on here from my computer but when I went to my tools/options/basics...it was still coming up as a homepage that I did not have checked for use....no matter how many times I deleted it searchqu came back...fortunately I have tech support & reported this to a technician...he deleted the searchqu url and reset it with http://my.yahoo.com/
This just happened. Now it's gone...he used a deep scan & my computer is working fine.
Thanks for your comments..problem solved here with a great deal of help from the info I found on this site...I would not have been able to clearly explain how I removed the downloaded programs associated with searchqu and where to look for it if it had not been for this site.
Many thanks to all contributors...this site rocks!!!
