I downloaded the trial because my university insists that every assignment I submit must be virus checked. So I installed it on my new MBA and ran the scan before installing my purchased software. It said everything was fine. But now, when I download anything or try to open any apps INCLUDING Intego's own Personal Backup software, it warns me that they are infected with the 'AHAHA malware' and tells me not to open them! So what on earth is going on? I tried a google search for 'AHAHA malware' with no results, the nearest being a Windows only trojan called 'HAHA'. But I don't want to risk getting any Windows viruses onto my system because my Uni is Windows based and will not open or mark any infected files. I am in a real funk over this, so I need help fast, and I will be very grateful for your knowledge. Thanks!
