How to manually un-install McAffe software.


I am not able to delete my virus (mcafee)software. It will not initialize when I click on the icon to scan for viruses. I recently installed a spy sweeper and they both were conflicking in start up. So I decided to delete them both and redo one without being in startup. My virus software is idle. Also, since then I am not able to connect to the internet. My homepage is gone and nothing will click open when I try to change my password. Could it be that I have a virus?
