what to do if a compter is totally virus infected and dead slow?

vikyy17 · Apr 1, 2016

my friends laptop is badly infected and running dead slow. his computer came with windows 8 pre-installed. i formatted the entire hark drive (cleared all local dive partitions) and installed a fresh windows 10 OS from a bootable usb stick. now everything very responsive, very fast after installing a fresh OS. but the windows is in free trail. since the laptop already came with genuine windows 8 pre-installed i do not know what to do in order to activate this new win 10. please help?

either contact the manufacturer of the laptop or microsoft and explain to them.
as a side note, you should've thought about this before hand

Look to see if there's a COA on the laptop. A lot of them have one, and I think you can convert Win8 keys into Windows 10.

Try and activate Windows 10 using the Windows 8 key. Otherwise, purchase a Windows 10 key from an authorized seller.

When it was new, you were offered the opportunity to create your own Factory Refresh DVD.
Save that somewhere for situations just like this.

The exact procedure varies, but it would be outlined in the user manual.

i meant that in a general purpose: before you actually do something, think it through.
think of it like this: before you format a hard drive, ensure that nothing important is stored on it.

- Remove drive from computer.
- Find a different computer, boot with OS
- Install BitDefender antivirus, Spyboot search & Destroy and AD-AWARE
- While machine is running plug in the other disk you took out.
- Verify it comes up as a drive letter.
- Scan the whole disk with malware scanners and virus scanners. Delete as needed.
- Re-instert disk back into machine.
- Enjoy your old machine.

I would try contacting Microsoft via their live online chat system.

I had a problem recently where I put in a new motherboard and CPU and RAM. Windows 10 popped up a message saying it needed to be re-activated. I inputted my (genuine) Product Key and it was rejected!
I had no backup image or Windows disk/iso image etc. so I was stuck.... I had previously updated to Win 10 from Win 7 and had lost the Win 7 disc and Win 7 Product Key etc!

After a chat with MS Tech Support they looked at my PC via remote assistance (with my permission) and then gave me a new Product Key which activated Win 10. All at zero cost.

I would at least give this route a try before shelling out on a new Key.

Tell "your friend" to re-install OS and Apps from scratch.
