Three days ago, I booted up my computer and the Welcome screen (right after logging on) took about 10 - 15 seconds to actually boot to the desktop. This wouldn't be a concern except for the fact that I installed my OS to a SSD and every boot prior to that one took a matter of one to two seconds. The only other oddity on my computer (Windows 7 64bit) is Firefox is now asking permission to make changes to my computer upon loading. I normally use Chrome, but I love Firefox for convenience on a few sites and it had never previously asked to make changes to my computer in the past. I scanned with Malwarebytes and came up clean on both drives. Is this a possible sign of infection or is something else going on here? I just built this computer about a month ago, so wiping this clean wouldn't be a problem in the slightest. I also have a second SSD I just bought that I need to install as a gaming SSD, but I want to make sure my rig is clean before I start adding drives and moving files.
