My internet been extremely slow lately, so i decided to run a scan for malwarebyte. I updated everything and started scanning. Towards the end of the scan, it frozed and showed the overflow'6' error and closed itself. I can't finished the scan!! I tried uninstalling and installing back. It didnt work. I think i did everything that I know of but I can't find anything that would permit this. I will upload the hijackthis log. THank you. hijackthis.log
