I thought I was updating my FLV player on my iMac today but I guess I grabbed myself a virus. It made YAHOO my search engines on both Firefox and Safari. I used Adware Medic and that solved the problem for Firefox and I was able to switch it back to Google as my default search engine, but Safari won't budge one inch from getting rid of YAHOO as my search engine--even though it says in Safari preferences the homepage is Google! I then downloaded Avast and that's presently running a scan. If nothing positive comes from that, does anyone have any suggestions? I cleaned out my Safari history and cache and rebooted numerous times but nothing has changed. Any help you can share would be greatly appreciated.
