My Mac has been very slow the last month or so, with a lot of beach ball use. I have fairly slow cable Internet, but it's slow other times as well (although more apparent with my browsers).
So I installed Sophos and tried to scan. After a couple of hours I discovered it was stuck. I shut down my computer, rebooted, and tried again, this time with "Caffeine" to stop my computer from sleeping. I let it run over night, and it was still running. A few hours later I was doing other stuff on my computer and it was stuck again. I tried again and shut down after it got stuck the next day.
This time I tried it lasted long enough to find a Troj/DocDrop-BM. Yesterday the Quarantine Manager pulled it up and says "Cleanup in progress", with the little in-progress icon to the right of it. A few times I clicked on the "lock to make changes" icon and gave my password. But the next time I checked that was locked again. Last night that was the status, with the scanning moving. This morning that was the status, but the "Items remaining" is not moving. It gets stuck with different numbers each time.
Looking up this trojan, I see that it is a Windows trojan, so it must not be why my Mac is so slow. My OSX is 10.9.2, my processor is 2.8 GHz Intel Core 2 Duo with 4 GB 667 MHz DDR2 SDRAM. My disk has 55.84 GB free out of 499.25.
