Remove Virus from your memory or USB

I've been once searching for the best way to remove virus from memory or USB. All I know is to use an anti-virus like AVG, Norton, Avira (Free Version) and some sort of it. But I don't really know a lot about hidden viruses. I need to know how to remove virus from removable devices other than the virus I usually encounter in my computer. A lot of people don't mind about viruses from their memory so when they connect it to another computer , it will automatically infect the said PC specially if no anti-virus is present. Unfortunately, you can't detect if you're infected or not unless you used an anti-virus. But still, using anti-virus is not a guarantee and it's impossible to eliminate them as well without learning how to really remove it. 

Now, I learned another idea from someone who freely shared it to us. It may seem basic, but I admit I really don't know about it. This is about the use of command prompt or CMD.

Take note about the image. So, to make hidden files appear, you have to type as shown above. If your memory is in drive I, just type DIR /ah. Then, files in that directory will appear as encircled above. Then, one by one make it to appear in the windows explorer by typing Attrib "FILENAME" -r -a -s -h. Type the exact format (considering Capital and small letters). Then, look into your windows explorer and you'll find all the files there.

Notice that when you see a file type as FILE FOLDER that's ok but when it is an APPLICATION TYPE, don't click and delete it if possible.

Hope This help.

Formatting USB Flash Drives

USB flash driveImage via Wikipedia
Speaking of flash drives, It is very important to always keep it safe from viruses. However, virus attack in our own flash drive can't be avoided from time to time since we are not sure when it will take place. People do usually plugged their flash drives to different computers whether in the office or in an internet cafe, not knowing that other computers are the main sources of viruses which can transfer to your own personal computer. The results, important files in it may be lost or it may not work properly which will lead you to formatting the flash drive.

Possible Reasons That Flash Drives May Not Work
  • Virus infected files by trojans or worms and any other types of virus
  • Formatting error
Be careful in copying files that you do not really trust. Some files have had virus attached on it. I'm sure all are familiar about it. But what I want to emphasize in this post is the normal formatting.

Quick Format Option

When you think that you already remove the virus on a flash drive and still its not working, formatting may be the possible issue. When your in a hurry, you usually do the quick format option to make it faster. Based from my experience, in formatting a flash drive is similar to formatting an HDD. I remember that when you reformat a Hard Disk Drive in a Quick Format Option, chances are when you try to install a software it might not be installed properly. There will be errors later and installation won't continue. Quick format option may or may not work properly, so I prefer formatting a HDD normally which slowly but surely. Therefore, do the same thing with flash drive. Don't get in a hurry!
