Pro. Everything is resolved, and everything works just fine. I did not know I had the information in the downloads from AVAST. Mine is for 3 computers, I have two, so this is great. I just went ahead and removed mssec.exe from the laptop, and installed my AVAST 5.0. It works swell. I have seen online how other folks have had serious problems removing mssec.exe on XP Home. My problem was finally resolved when I installed the free version of AVAST which automatically removed the pesky, lagging behind file from it. Thank you, and I am going to post another question on chkdsk after looking through searched items. If I find the answer, then I will not post, right?! Right!
