|Are you able to boot into Safe Mode?.. (You'll be able to do this by booting the computer and tapping the "F8" key). If you can get there, try using Malware Bytes. Another option you have (provided you have a blank CD/DVD available, which will also be the easiest for you) is to use the Kaspersky Rescue CD: http://support.kaspersky.com/faq/?q...|
Then burn that .Iso image to the disc using CDBurnerXP: http://cdburnerxp.se/en/home
After it's been successfully burned, reboot the computer and press "F10", or whichever key takes you to the Boot menu. Once at that menu select your "CD-ROM/DVD Drive" and press "Enter". The disc should then start to load.
