I have run a thorough scan via both Sophos and ClamXAV (thank you BDAqua) and neither program detected a virus, however, when I open Safari and choose a Google search, the following url appears in the window:
http://www.google.com/webhp?hl=en&tab=nw.
Additionally, in google news, this url appears: http://news.google.com/nwshp?hl=en&tab=wn&pog=false
Safari seems to be up-to-date. Version 6.0 (7536.25)
While these urls do not seem to be automatically redirecting my search, I am concerned that this is either a sign of malware, spyware or some sort of trojan and my data and personal info may be in jeopardy. I am a relatively (Dec. 2011) new Mac user, but had this same issue on my PC before. I apologize, if this is normal, and I am overreacting, or if I'm not adequately describing the issue.
Would installing the latest OS update help?
Thank you for your thoughts and suggestions.
