You can download another anti-virus or antispyware from another computer like from a friend, then save it on a flash drive and transfer it on your computer. But the flash drive might get also infected. If that doesn't work, you might just try reinstalling your OS.

First of all, if you have a system restore point use that.
Start up your computer in Safe Mode with Networking and see if u can download the avg update.
If that doesn't work, then try downloading other scanners with other computers and than transferring them to your computer and scan.
