How do I know my computer has been infected with a malware?
MacBook, Mac OS X (10.6.8)
Welcome to the Apple Support Communities
If you have a Mac, I doubt that you have a virus because there aren't any viruses for OS X. See > http://www.thesafemac.com/mmg
Anyway, if you want to use an antivirus, you can use ClamXav or Sophos, but as I said, you don't need any of them
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
If you require anti-virus protection I recommend using ClamXav.
If you have a specific reason to believe you're infected with malware, please say what it is. If you don't have a reason, there's no need to do anything.
The subject indicates you got here from reading about an old Java update. How did you get from there to malware?
