Please follow the instructions in the link below to download HijackThis to a folder on your desktop, then run the program, save the log it creates and then post the log to one of the special forums that read those logs...They should be able to read the log and help you clean out the pest. DO NOT POST the logs on these CNET forums.
Hope this helps.
Somehow, my computer has got infected with a spyware that opens www.us01.xmlsearch.findwhat.com and then different advertisement pop-ups. It is also causing frequent crashes of internet explorer. I have tried removing it by Ad-aware, Microsoft spyware and spy sweeper, but I have not been successful. I cannot find this new software through 'Add& remove Programmes' in control panel.My McAfee virus Scan also is not clearing it. Can someone help me please regarding this issue.
