How to Flush DNS in Mac OS X
If you are an Internet or web developer or do a fair amount of administrator tasks on your Mac, then the requirement to flush DNS cache will arise. Depending on what version of the OS is installed on your computer (Leopard vs Tiger), there will be a slightly different command to flush DNS.

Step 1 – If Mozilla Firefox is installed on your computer, exit the application if it is open.

Step 2 – Open the terminal on your computer.

Step 3 – On a computer running Lion (Mac OS X 10.5, 10.6, or 10.7) enter the following command followed by pressing the “return” key:

dscacheutil –flushcache



I'd download and run a scan with Avast too
