I have a windows xp sp3, dell optiplex 760, on which I cannot remove mcafee siteadvisor enterprise plus. We use McAfee enforced antivirus sonicwall client on our machines, but are moving over to vipre. Unfortunately the mcafee removal tool got run on this machine, which took out the mcafee enforced antivirus client, but unfortunately it did not remove the mcafee siteadvisor. I tried to remove the mcafee siteadivsor from the add/remove programs list, after the removal tool was run, but it will not come off, and now is causing all kinds of problems. It is causing a lot of error messages. Please let me know if there is any kind of removal tool to get this mcafee siteadvisor off, or if you have any ideas how to stop the error messages. Please help!
