Answer #1
, there many ways to fix the laptop. First of all, have you tried logging into the Safe Mode. If you can do that, back up the data you need. Then, perform a full system scan using Kasperksy Anti-Virus. If you cannot do that, then I suggest you get a 2.5″ hard disk (laptop hard disk) enclosure package. After that, take out the laptop drive and put it into the enclosure. Then, connect the package into any other computer. After that, scan the drive using Kaspersky Anti-Virus. Let me know what happens next.
Answer #2
An alternate way would be using a bootable solution. I would recommend Ultimate Boot CD for Win or Avira Rescue Disk.

you could use data recovery… or get data back even if u had formated ur pc, (another thought u should have external hardisk where u use dual OS (one on ur pc hardisk and the other one inside ur external hardisk), eventhough ur PC infected by virus (at home) but u can run for scan with the clean one inside ur external hardisk. just don’t forget to always backup data…. and install Internet security.)
