Gooday folks. I downloaded The "Full Monty " ISO, it took over 24 hrs and is now sitting being scanned for viruses by my paid for AVG. How long should I let this process go on for?
Till its ready or stop scanning

It is like scanning a complete DVD, you are sure there is no virus on the DVD but still waiting

My advise, stop scanning and burn the iso, reboot and install, never scanning again.
Have a good day and fun with your new Linux box.

P.S.
Don't forget to choose manual partitioning with FullMonty you need a 20G / partition for the system where the automatic installer does 7 or 8, enough for the standard PCLinuxOS iso's but not FullMonty.
