Laptop completely reset?

Can any viruses still get my old data

No. Once the laptop is completely reset, there can be no virus there.

No meant when I reset my laptop and then download viruses whether they can still get old data

No, if the data is gone, then no virus can get to this data.

Yes, theoretically you have to fill a hard disk completely 9 times so that all data is really gone. But the virus really has to be specialized on the data.

I would say that is damn improbable but yes

But they are not gone…
