Q: How can I safely verify if my system has malware/adware or possible virus on MacBook Pro (2012) using OSX 10.9.5?
How to run a SAFE test on MacBook Pro (2012) running OSX 10.9.5 for malware/adware or possible virus? A few nights ago I was online and all of a sudden Google Chrome browser stated I had a trojan or virus and asks to call 800# which is a known scam and I did not call nor allow any remote access but I am concerned that my daughter MAY have downloaded something she shouldn't have from the internet. (possibly, Skype because I saw where it had been downloaded a few days PRIOR to this issue but she must have either not fully downloaded the program OR deleted it after using it since its not I no longer see Skype on my system)
Specifically, the box that came on the screen stated:
The page at emergencyvirussupport.com says:
"Your Browsing Activity Has Ben Restricted"
**Your system has been infected with critical Spyware/Malware/Trojans**
A browser lock is in place to prevent further infection of your network, and the network of others.

Prevent this page from creating additional dialogs (Has option to check a box)
I tried to close the page and was unable to do so and eventually had to "Force Quit" and log back on. Under history I see where "Network Defender" and "EmergencyVirusSupport" is on system at 8:12pm which was the same night that the issue started. I tried to upload the screenshot but its not allowing me to and says file may be too large but Ive uploaded pics on here in the past without any problems so I didn't know if this may have to do with something bad being downloaded off the internet?
Could someone please help me with the steps to safely runs test on my system?
I want to add that approx. 2 weeks ago I started having issues with Safari and Chrome not being able to "verify certificates" and in my Keychain Access I see where several pages have a red "X" beside them and are expired. Could this be a part of my problem too? Thank you very much! Much appreciated!
MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.5)
