Hi Shazzamara,
please tell us which Win you have, and where exactly the infected files were found (full path and filename, see avast’S report/log-file)

Blaster can be removed by avast’s cleaner:

but it’s important that you apply ALL Windowsupdates, or it will again reappear over the net

Here’s some info/removal instructions on crypto:

sound a bit tricky, we need to know where it was found/if it’s active…
:wink:
