Antivirus Deleted some of Blocks 129 and 130?

[bitquestions]

My question is more technical and moral. I'm wondering if a person downloads a cpu miner and the antivirus knows it's only meant to run in the background (to use a many cpu's to make one person wealthy) and so deems it a virus or malware and deletes it (with the blocks) does that effect bitcoin? My malwarebytes detected the miner as I tried to unzip it. Then was able to remove it. Then a deep scan from Avast antivirus found something encoded "block 129" and "block 130" and I deleted them. And that's moral question.

Files called blk00129.dat and blk00130.dat were the ones in question.
