Thank you so much for your continuing attention! Forgive me, but I'm not particularly computer-savvy, but I can follow clear directions... (if not too complex, like the above steps you outlined - I think I'd need to find a more computer-savvy person to help me with all that)... how can I "post the requested logs" for you? And do you mean the logs from the scans I've already done, or do you still want me to complete all of the above steps first and then post logs from a subsequent scan? an UPDATE - last night I ran a scan and made the following notes about what happened... maybe this will be enough for you to see what's going on? Wed. 6/11/14 - 11:12pm – scan found 2 detected items: Location Type C:\Program Files (x86)\Flash Update\winclient32.exe File C:\Program Files (x86)\Flash Update\winclient32.exe Process HKLM\SOFTWARE\WOW6432NODE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN Windows Client Registry Value (The third "location" above is not complete, but it was all I could see of it... and between RUN and Windows toward the end, there was a vertical line, neither forward slash nor backward slash... I can find no such "vertical line" symbol on my keyboard to reproduce it!) I selected “Quarantine All” and “Apply Action”, got a small window saying: All selected items have been removed successfully. A log file has been saved to the logs folder. Your computer needs to be restarted to complete the removal process. Would you like to restart now? (I did) I forgot to mention earlier that one of the things I noticed (besides the pop-up windows asking me to "update flash") was that upon starting up my computer, a small black window would flash on my screen for a fraction of a second and then disappear (sometimes it stayed for as long as a whole second or so, and I was able to make out the words "flashupdate" in the address in the top bar of that window before it disappeared. Anyway... since last night's scan and removal action, I have not noticed that black box flashing upon startup anymore! What do you think? Many thanks, Alex
