Zone Alarm virus scan detected the following virus, but gives an error when I try to remove it:
"Memory: was found in \\?\globalroot\device\ide\ideport1\owprppbw\owprpp bw\tdlwsp.dll on 9/21/2009 7:35:32"

The virus seems to be a browser hijacker. When I click on a web link, I usually get taken to some other site, often a shopping or advertising site, rather than the link I clicked on.

What can I do to remove this virus from my system? Thanks for your help.
