I think I have cyber bugs in me. Lately, my drafts are about computers, well simple things that I know. Ahhh, why not :D
This time is about computer virus. It is a pain; easily spread, hardly killed has become some sort of policy, especially for worms and trojan horses. People with antivirus; any kind of antivirus, even though you update it regularly, don't trust it too much. Not every time it will work, although most often it will. Computer viruses are like virus that causes flu; they evolve. You come out with a new solution, they come out with a new 'strain'.
Virus problems is very rare in MacOS and Linux operating system; almost none. But for windows users, especially XP, you are vulnerable to almost every single virus of millions available. Some viruses are just nuisance with no big threat on the system, but some are going to make your turbo charged internet connectivity slowed to the snail level, or perhaps your startup speed time extended up to 30 minutes or even hours.
Prevention is always the best step in handling with diseases, and it seems like the step is highly applicable and effective in term of 'computer diseases' too. Whoever infected once by dangerous viruses knows the miseries of unbootable system, unmountable volumes, inaccessible harddisk partitions, especially when you have several critical assignments to submit.
From my observation, the main vector of the viruses is thumbdrive and other portable volume of memories like memory cards.
These several points to keep your computer safe, just before the virus invaded in. Most of the times, it works.
1/ Avoid autorun especially the thumbdrives. You can disable this in the Group Policy setting. Access group policy by Run (start button+R) and type "gpedit.msc" (without quotation).
2/ Make opening Explorer to access thumbdrive a habit. Shortcut for opening explorer: Start Button+E. Do not double click on the main panel, but click once at the structure view of the side panel to safely access file. These first 2 points are crucial as the invasion normally occur at this point.
3/ Make visible the hidden files including the protected system files. Access Folder Option in Control Panel, and go to View (second tab). Mark "Show hidden files and folders" and uncheck "Hide protected operating system files (Recommended)". Be sure which is which, and when there are suspicious executable files, permanently delete the files (Shift+Del).
4/ Antivirus with no regular update is a nuisance. Make sure it is regularly updated.
Those four are the fundamentals I know. Do add some to the list.
