15in, early 2011 Macbook Pro suddenly incredibly slow

Within the last few days my early 2011 Macbook Pro, which I've had for a little over a year, has become incredibly slow. Simple actions (opening applications, loading webpages) can cause the computer to slow down and load (rotating rainbow mouse icon) for prolonged periods of time, and the computer takes an incredibly long time to start up. I've run anti-virus software to see if that was the issue, but there were no virus or security issues detected.

When not doing any function the computer runs fine, but even trying to open a pdf file can cause issues. Does anyone know where I can continue my search to diagnose this problem? I'm more than willing to provide more information in search for said diagnosis as well.

You don't need it. Uninstall it, repair permissions and restart your computer.

You also forgot to mention which os you are using. Your system profile is a complete blank.

I apologize for lack of information. Running Mac OS X Version 10.7.5

ds store, I read over your 'why is my computer slow' page, and could find no indicators there of this issue.

I am in the process of repairing permissions, and will post an update when that process is complete.

I repaired permissions and things returned more or less to normal. My computer seemed to be running a bit slower than average, but I resolved to let it be and see where things went.

This morning the computer became incredibly slow again, i repaired disk permissions again, and again things are bearable.

I tried verifying disc permissions and got the following response. I don't know if this means anything, and apologize if its a bunch of random nonsense that's not helping anyone.

Finally couldn't take it anymore. I reinstalled OSX from recovery (CMD+R at boot) and now everything seems normal. So happy that I can actually use my rMBP again.
