(My apologies! This is a duplicate thread. I erroneously posted this in the Windows 7 forum first.)
Windows 7
Macbook Air
This laptop belongs to a friend, who says they encountered issues when one of his friends tried to install adobe acrobat. After the computer was rebooted, I'm told Firefox began to look different, and there seems to be more things going on in task manager. Also, instead of uninstalling acrobat, the person did a system restore to a time before the program was installed. Now the acrobat folder is still there, but will not delete (pic below.) There is no uninstall program function. Also, spam mail from "MyPCBackup" started coming in through Gmail, and it is unusual for spam mail to get in through that account. I don't know much more but am hoping you can tell me whether the machine is compromised and how to make sure it is clean!
