windows problems

The computer finally had a virus. Was able to "heal" it with AVG.
However decided to reinstall windows anyways so as to completely cure
the system.
Took a day to install after upgrading the file system to ntfs. Also
decided to stop using the admin account for anything other then well
"Administration".
Had to install everything again and also removed ability to execute exes
for the limited accounts from the data drives by using polsec.msc.
Hmm I guess it is almost as secure as linux. The limited accounts and
the new file system should prevent files from getting hit by viruses.
But still I have an updated antivirus and am also updating the windows
updates to prevent issues with the computer.
