As philiparas4 said, it is NOT a virus, it is what most call a FALSE positive. In other words, your scanner couldn't figure out what virus it actually was, so it gave out the closest match it can find from it's database. (more or less, it's how I describe it anyway). If you do a lot of editing, using programs such as this, or others that make changes to a another programs files or even registry , to only name a few, you will come across a lot of "false" positives. So when you find one, SEARCH the place you got the program from and see what others say about it. For instance, you got this program here, so, search the forums here to find what others say about it having a virus in it or not. So, please, if you find a "virus" in one of the program offered on these forums, chances are there going to be a false positive as I have NEVER found an actual virus yet. Again, SEARCH for the answer to any "virus" found on these forums..
Ok sorry, had to write some thing as I see this all over the place, not just on these forums, people need to learn to search and check out what is actually a virus or not, instead of jumping the gun..
