So yesterday I got an ever so lovely virus on my computer. Apparently it's a well known one and pretty dangerous, but it's the i4jdel0.exe virus. Microsoft Security Essentials said it found a virus (different one, don't remember what it was called), and that it successfully deleted it. I figured "better safe than sorry" and opened my temp folder where it was located, and found i4jdel0.exe there. I deleted it, it came back, I deleted it again and emptied my recycle bin and never saw it again. I noticed things like iTunes wouldn't open (library is locked), a small window would pop up when I opened firefox (security isn't on, or something like that). Buttons on my keyboard wouldn't work (namely alt, ctrl, and shift). So I ran a scan on my computer, found nothing. Ran my computer in safe mode and scanned, found nothing. I gave a sigh and decided I'd better just wipe my hard drive and reinstall Window 7. I put all the stuff I wanted to keep (music, photo's, etc.) onto an external and began the process. I forgot to wipe my partition the first time I did this, and the windows.old folder was there. I attempted to delete it as I began to get all the programs I had before reinstalled on my computer. I got iTunes and it wouldn't open (library is locked). Extremely frustrated, I reinstalled Windows AGAIN and made sure to wipe my partition this time.
This brings me to where I'm at now. I open my task manager and I see atieclxx.exe, csrss.exe, and winlogon.exe all listed in processes without a given user name or description (cannot end processes without clicking "show processes from all users, upon which ending csrss.exe crashed my computer). I asked my friend who told me to delete them from my System32 file (and to be safe, delete everything in the folder, too). Well I can't because of TrustedInstall and not having the permissions to do stuff, etc. Well I cannot change my permissions to allow me to delete any files (properties -> security all the buttons like add and whatnot are greyed out and unclickable). Tried in safe mode, but that didn't work either. Now I think "I'll go see what I can find in my temp folder" but I cannot gain access to C:\Documents and Settings at all (can't even see it, but when I put it into the command bar, a pop up comes up telling me that I cannot access it). I'm also a little confused because I reinstalled iTunes to see if it would open, and now it does. I'm prepared to rip my hair out from all the frustration this thing is giving me. Half because all my work on it yesterday was for naught, the other half because even though I've had Windows 7 on my computer for a few months now, I've yet to set a backup on my computer (seriously, I feel like a moron). I've been on these forums before and I know you guys know what you're talking about when it comes to this stuff. Please help.
Edit: I feel this is important. My laptop has a total of 3 partitions. My C: drive, and two that are for Toshiba type stuff? I guess? One is 1.5 gigs, the other is like, 70 gigs. I didn't wipe the other two.
