Viruses
I have what some may call "exams" coming up.
I've also noticed some weirdness with my compy. Start Menu stopped functioning...menus and the address bar stopped working in IE, and my computer was generally slow.
I did a virus scan and found I had a virus. This particular one would stick itself onto any EXEs and eat up your memory. My first virus scan removed the virus itself. I did a subsequent virus scan, which scanned EVERY exe file that I have on my computer.
Turns out that little virus spawned itself into a total of 1,197 other viruses on my computer. After that was said and done with, deleted and corrected, my computer feels faster, smoother and it even looks younger.
So with my old laptop new again, I return to study and the permanent bedroom I call the Library.
