Hello, yesterday my computer started acting very strangely and it clicked on random things on it's own and typed random words and letters by itself. I looked this problem up and found out that this problem is a trojan virus. So I scanned my computer using avast while being in safe mode. There seemed to be no infected areas (there was one thing that couldn't be scanned but it was only a terrain map thingie on one of my steam games so I ignored it). I went back to normal mode and the problem continued to occur so I used a USB flashdrive to save some files and documents. I tried to save my iTunes library with my iPod but the iPod frooze on the "Do not disconnect" screen. I even hooked the iPod to another computer but it's still stuck on this screen. Is my iPod and the computer that I plugged the iPod into infected by Trojan now? Anyways, I reformatted my computer and I plan on deleting the "Windows Old" folder. After reformatting the computer, I used it for about 10-15 minutes and found no problems. Should I still delete the windows old folder? Is my computer 100% clean of the Trojan virus? Should I do anything else or is my computer fine? Thanks.
