Looks like I got a virus in my system or some other sort of damage from visiting the download site vixy.net.
Read the email I sent them:
[i]Hello
I just tried the flv converter to download a youtube video in avi format.
Somehow it caused problems to my system.
I 'm trying to access the folder where the video was save using “my
computer” and I get a microsoft explorer error (sorry for the
iconvenience).
What can I do about it ?
First I tried to rename the download file in the download dialogue and
it was saving only 136 kbytes from it, instead of the 3 Mb it was.
Then I did it again keeping the name you give (a long series of
numbers) and it was downloaded.
Then I renamed it in the computer and the problem started.
So far the problem appears when I open “my computer” and try to open
folder “my videos” where your file is.
Please advise.[/i]
I have n’t an answer so far from them and right now avast is scanning my system.
