Hello everybody.

Here something that's been on my mind. Some time ago, I downloaded a zipfile from a website.

After the download was completed, I ran a virusscan, and the virusscan told me that the zipfile

was infected with a trojan. I decided to remove that zipfile from my computer, so I went to the

folder where I had downloaded the zipfile and I right-clicked the zipfile and chose the remove/delete

option.

Now here is my question: By doing what I did, have I really removed/deleted the infected file from

my harddrive permanently, or have I just removed/deleted the "reference" to the infected file.

I've been told that Windows does not really delete a file that you have, "right-clicked and chosen the

remove/delete option", it only removes the reference to that file. So now I'm wondering weather my

computer may still contain the infected file, only now I cannot see the infected file or find it.

I should add, the reason I removed the file manually like I did and did not use the "remove" feature of

my a-virusprogram, was that I had not opened or executed the infected file in any way so my computer was

not really infected, it only had an infected file residing in the harddrive, so it seemed easiest to do it the

way I did. Also sometimes a-virusprogram can detect a trojan/virus but it cannot delete or quarantine it,

so if you are in a situation like mine, where you have not yet executed the infected file, just right-clicking

and deleting the file seems the easiest. Thats all folks, forgive the long letter................

You are correct. By deleting the file you have only removed the reference to the file, the data is still on your drive. However, there is no way for this data to now infect your system so I wouldn't worry about it. Eventually this area of the drive will be overwritten with something else.
The power of accurate observation is commonly called cynicism by those who haven't got it.

If you do want to remove all traces of the file, consider using a program like Eraser.
Instead of removing the reference to the file, it will overwrite the file, on the spot.
It also gives you the option to Erase the Recycle Bin.
It makes a number of, user set, passes over the file, with a series of 1's, and 0's, thus Erasing it.

It's also a good progra, for removing sensitive data, from your computer.
