Recently I renewed my Norton AntiVirus from 2005 to 2006. I think almost every year at this time of the season I'm renewing it. I haven't had any serious problems so far caused by any viruses, but from time to time I try to scan the whole things. In fact, I don't like this process because it takes me very long time. To complete the whole scanning it probably takes about 6 hours. So, I usually let the computer on and scan while I'm sleeping at night. :)
This time, when I installed the new Norton 2006, I don't remember how it was when I installed 2005 but, it needed to scan the whole things at first to let it sit safely on my computer. I didn't do this, because it takes me long time. And I went back to my work. I was working on my graphics that has relatively big file size. When I was saving the file, my computer started to make very suspicious noise! So, anyhow, I saved the file and try to reboot the computer. Then the computer could not shut down safely. It said it is because of the newly installed software. And, it started to make bigger scary noise!! I immediately turn the power off.
To make the long story short, I rebooted again and it was fine but I had to make Norton 2006 scan the whole files.. I did it. I had to. And it was fine. But it took me almost whole day... After all, I thought it's better to back up the files that I was not using quite often, and eliminate them from my drive to make more blank space. Now, almost half of it is empty. I feel so good and almost all of my files are well preserved again. :)
