I am using Opera web browser. I had no issues up till now with Opera, but recently I noticed that all my searches in my web browser are getting redirected to some unknown web sites. I am using ASK toolbar for searching. When I scanned my computer using my Kaspersky anti virus it detected Backdoor.Win32.Agent.andi. I was successful in deleting this malicious program, but my web searches are still l getting redirected and on scanning with Kaspersky there is no trojan or virus detected.
