tow days ago , I was downlonad something from web site than my computer says there is a torjn virus and my date under attacked . and I downlonad malware anti , and it found 27 malwares on my computer and I removed all of them , but today it still say there is a torjan virus .
Anyway - Are these new virus or old that never were cleaned? if you've updated all of your security products (Defender, AV, etc.) and can't get rid of a virus, then you might need to completely reformat the computer and rebuild it from scratch.
