Hi all, Recent happenings when logging on to one of the sites I visit is strongly suggesting that the security of my computer has been compromised. One of the Mods there suggested that I: "Backup all your important data to an external hard drive, scan it with as many different anti-virus / anti-malware / anti-spyware / anti-rootkit programs as possible (preferably portable versions), then re-install your OS and create a new account..." Before I do all of the above, would it be equally effective to simply roll-back my computer via Time Machine to a date prior to when I could have possibly been "infected"? If not, does anyone have any suggestions about effective anti-malware/spyware/rootkit software for Mac? I'm currently scanning it with freeware called Avast, which was highly rated. Would that find the problems mentioned above? Running most current versions of OSX. thanks in advance!
