webroot can't find Cryptowall 3.0
I was hit with Cryptowall 3.0 on 6 Feb. Helpful experts on another forum guided me through a lengthy, thorough cleaning procedure, including numerous scans and logs.
Today, 30 days later, after booting my laptop, Cryptowall did its thing again -- new files are encrypted, old files are encrypted twice now, and the .png and .txt ransom files appeared. No website access or e-mails; the machine was just sitting there for a couple of hours. It looks to me like this virus hides really well. Now I've just finished running Malwarebytes, Avast, and Webroot -- so far, nothing I've tried can detect it. I've been reading speculation that the virus cleans up after itself and hibernates in a hidden boot partition.
My question: can you guys help me truly clean this? Or I should just give up this laptop?
Thanks.
