download malwarebytes its a free software and has worked for me`when i had similar problems in the past ,burn to disc on your laptop then run it on your pc

justh8me, I don't know what it is but there are plenty of things to try to resolve it. At the very least, your browser appears to be hijacked. Assuming this is Internet Explorer, try running the "no add-on" version in Start -> Accessories -> System Tools -> Internet Explorer (No Add-ons). That might allow you to download some malware scanners.

It also seems as if there is a problem with your Internet connection, as if the malware has cut off access to definition updates. For this, try rebooting into Safe Mode. Restart the system and tap the F8 key when the BIOS/Setup screen or Manufacturer's logo screen appears. Keep tapping F8 until you get to the Advanced Boot Options Menu where you can select "Safe Mode with Networking". Hopefully, this will allow you to use your network without the malware interfering.

If that still doesn't get it, you can try creating a boot disc on your laptop for use on the other system. Try the other steps first and let use know how it goes.
