My macbook pro is acting very odd and I have just found out that my other half has read an email via my laptop on her hotmail account that was a scam- it read" Access to your online account has been suspended (term : violation of use) to confirm your security details click here, failure to do this may result in access to your savings being blocked). She has alerted her bank but did not save the email and it doesn't appear to be in her trash or anywhere. I need some kind of virus detection freeware that will help to detect this- please help what do you think has happened? Is it a coincidence? I want to search my computer, its acting really weird slow when I type its taking ages and my saved tabs in bookmarks have all opened up with no saved passwords etc. Please help.
