Hi everybody, I have just a few quick questions about factory resetting my MacBook Pro 15" circa 2010 Maybe I am just being paranoid, but I feel like my computer my have some sort of virus or rootkit. My personal admin account has been running really slow compared to my Guest account, about a month ago it said my Facebook was accessed from a foreign location immediately after I changed my password, and now it is being strange and saying I am blocked from Omegle for allegedly "possible bad behavior" despite the fact that I have never been to that site before. There really hasn't been any other weird things, no redirects, no loss of control of my computer, etc. The only reason I found out I was banned from Omegle was because when I was researching rootkits I stumbled upon someone talking about a rootkit that prevented Omegle useage. I have run an Avast scan, and nothing was found, but unless someone can assuage my fears, I want to do a factory reset. So I have a few quick questions 1. If I factory resetted my Laptop, would the virus or rootkit that I potentially have survive the reset? 2. My computer's disc drive acts very strangely, sometimes it works, sometimes it doesn't. Usually it works for a little, and then stops. Sometimes when I reset the PRAM it will start working again. If I factory reboot it, and the disc drive doesn't work, what will happen? Lets say its half way through the proccess and the drive stops working, will my computer be permanently damaged and stuck in purgatory? Or, what if I put the disc in and it won't start at all, but after I have committed to the process? For example, what if I start the process but the drive doesn't work, can I just cancel it? 3. If the disc drive doesn't work, could I use an external CD drive? 4. If my computer does have a virus, what are the odds that it could be on Time Machine too? If anyone can answer any of these questions, I would really appreciate the help. Or if anyone has any insight about what may be the problem with my computer, I would appreciate it. I trust Avast, but from what I have read rootkits can hide from virus scanners. Thanks in advance to anyone that can help at all!
