If I posted this in the wrong area, I apologies and please redirect me.

Ok, so I asked this on another microsoft forum, but the help they provided, well, didn't help.

So I had to do a factory restore on my laptop recently because a program called CSRXX.EXE, an apparent worm, took complete control of my computer. This "application" would come up every time I would start my computer. I tried doing system restores, but most of the time the system restore would cause an error and not work. It wouldn't even let me into safe mode. Eventually, my desktop wouldn't come up at all so...there was really no choice.

While all of this was happening, I managed to back up all my important files, mostly pictures, audio, and word documents on my external hard drive (Western Digital Elements 1TB). My external hard drive already had important programs backed up on it as well. I was hoping that this would work, but as it turns out this virus spreads through USB. I went to an online scanner called ESET and when i would look for things to scan the virus appeared on my external hard drive...however the scan didn't see it as a threat because it didn't pick it up. The virus appears as this on the scanner: Posted Image also, according to some research that's how the virus will appear.
(If you can't see the picture well: https://ssl-proxy-updated.herokuapp.com/78b641cc630a25668b627f0bd42b5ded0b0b4c63/687474703a2f2f6939352e70686f746f6275636b65742e636f6d2f616c62756d732f6c3133382f536f6e32382f6578616d706c652d322e706e67/)

*my resources: http://www.threatexpert.com/report.aspx?md...863da1cafea7b3f

Now I didn't move the files back on my computer, so as far as I know my laptop doesn't have the virus again.

The last forum I was on told me to run a program called Malwarebytes and Spybot, which did not find anything on my external HD. In fact, the only way I can tell if the virus is still there is if I do an ESET scan. The ESET scan won't find the virus during the scan, but if you try to tell the scanner what to scan, the virus can be seen (refer to picture above).

I need the files and programs. I am an artist, writer, and voice actor. I animate toons and voice in my own plus online toons. Plus some pictures I drew I got paid to draw, so I can't afford to lose any of these files. The programs I can always reinstall, but the pictures, documents, and audio I cannot replace...at all. So I am asking, is there any way I can rid myself of this virus without harming my files, or if there is any way to transfer my data without losing my files? Please I really cannot afford to lose these files.

Thank you in advance.

Rob R.

Your photobucket image comes up as either deleted or moved.

Only thing I see in your image on your post is desktop.ini in the recycle bin but no sign of a virus being detected in this image.

iff you feel you are infected with a trojan or virus try posting in the BC AII fourms at this link. http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

perhaps it would help if I enlarge it.

if you go into my actual EHD you do not see the recycle bin.

However, the "Recycle bin" doesn't read recycle bin. it reads $RECYCLE.BIN and desktop.ini. That's what the virus does, it creates a fake recycle bin, then uses the desktop.ini to get into explorer.exe and stops it from working.

but I will post in that thread. thank you for redirecting me.
