My wife got the ransom.crypt.xxx virus on her laptop. I was able to decrypt all of the files using the Kaspersky tool and I can get malwarbytes anti-malware to update and to run and the scan returns nothing... however, I am still not able to update, scan or install any new anti viruses even after running rkill. i downloaded to a thumb drive and ran rkill, tdsskiller and adwcleaner and they found nothing. 


Also, for some reason, there are no restore points before the problem started.

When unexpected issues arise with anti-virus software, I generally recommend a reinstall which resolves most problems. If that does not correct the issue, then an uninstall and use of the vendor's removal tool (if one is available) for performing a clean reinstall. If there was a previous anti-virus installed, you need to ensure it has been completely removed. If not, there may be conflicts when attempting to install a new anti-virus to include it not being recognized by the Security Center.
