Thanks very much for your rapid reply! Restarted but could not update Malwarebytes. Got Windows message "had to close, tell Microsoft about this?" - further digging found this error log file: <?xml version="1.0" encoding="UTF-16"?> <DATABASE> <EXE NAME="mbam.exe" FILTER="GRABMI_FILTER_PRIVACY"> <MATCHING_FILE NAME="mbam-dor.exe" SIZE="381712" CHECKSUM="0x43554EDE" BIN_FILE_VERSION="1.0.0.0" BIN_PRODUCT_VERSION="1.0.0.0" PRODUCT_VERSION="1.00" FILE_DESCRIPTION="Malwarebytes' Anti-Malware" COMPANY_NAME="Malwarebytes Corporation" PRODUCT_NAME="Malwarebytes' Anti-Malware" FILE_VERSION="1.00" ORIGINAL_FILENAME="mbamavenger.exe" INTERNAL_NAME="mbamavenger.exe" LEGAL_COPYRIGHT="

While running full scan got error code: 722 (0,7) followed by 721 (0,14) - was instructed to report these to Malwarebytes. Checked the pinned post which did not have any other fix instructions. Also later got: The instruction at "0x77c47631" referenced memory at "0x00000000". The memory could not be "written". Please advise and let me know if I can supply any further details that would help. Thanks for any and all assistance.
