an dog head appears on the right bottom coner of my winxp recently. i mean an application has been installed in my PC without my authorization. the dog head appears right after the internet connection netzero starts. i tried to kill it through task manager, by stopping the process tree of supicious tasks such as cashback.exe, bargn.exe, nls.exe, but they apprears in a second.
anybody could help to handle this problem?
thank a loooot!
