Yes I assume from what I read at the wiki that the iso was not tempered with but it is a possibility sorry but that is could be from what I read at the wiki site for sha 1 codes..
Wins is probably where it came from there is currently at least 1 person on You tube talking about an issue I had with it it deleted half of the programs I had on 1 drive and scattered the games all over the place in unusable form.. I thought it came from a 3rd party vendor that Asus uses for the light show on my video card. but since this video is up it may of come from wins itself.. I don't really know but it seems it also works in linux too. when I installed the original I'm afraid I did not watch it very well and forgot I needed to update it after the install.
well if I boot the computer with the hard drive program that is installed it is impossible, for ME to download and install anything to the computer it doesn't even ask for my code anymore.. it gradually got worse until it reached its current state. I've never tried to use a de bug program like avg or the like. and at its current state I think it would refuse to download those files it is now in the grub file location and has immediate access to anything I do and it seems the computer too. I tried installing a new version and then format the drives. I found it by accident. what happened was I moved the file out of root.. I got to it by using an old tried routine of opening the program in new tabs until it opened the program.. i didnt need a security check to open it.. don't ask cause I don't know how.. it just works I found out about it because I'm always tinkering with the computer. what happened I installed k3b in deb and when I opened it up the file there along side of the new dl iso.
and I could not get them to clear out.. but I could get the iso to burn by right clicking it and select burn iso.. i assume that was safe. but I wanted to check it this is the iso I did that with. I also tried to install a custom new version of windows that is what let me see the drive is wrong. in windows once you get a 0 partition answer if you run the remove partition again if anything is still there is shows up as an area that is not in the un-partitioned area.. and if you try to delete it it either deletes or you get a messaging saying it can't delete.. its about 20 gigs in size there which is much bigger then just a saved area for extra bytes for the hard drive to use as they go bad. that is all i've basically tried, I disconnected the hard drives from power so the ssd would not run and put in the iso disc. that is all the computer is running on at the moment I have 12 gigs of ram.. plenty to run the startup and go online I just can't write anything anywhere
edit to first paragraph I thought the program would delete everything on the disc's it did not. so I missed that by not paying attention. to install linux
