Help!: Someone used my system to access "restricted" sites.

Mac Virus/Malware Info

 

Sure... Someone else accessed those sites ^^

But in all seriousness, the likelihood of you actually having a virus is still low. If you're that worried just google for a trusted virus scanner for Mac.

 

Read the link I posted.

 

There is very, very little danger as long as the user is not a complete idiot. You know who the user in question was; the fact that you know what they did proves that he or she is not the brightest spark (hope the evidence was in the Safari history and not some other evidence )

There _are_ sites that will suggest that in order to watch their goods you need to download some Quicktime plugin. If you believe that, and then enter the administrator password and click on Ok twice even though the OS warns you, then you can catch _anything_. But if the user didn't know the administrator password, and didn't have access to your credit or debit card then there is very little danger actually.
