Didn't know where to post this. Black screen of nothing?
A few times when I tried to start up my PC I got a black screen with a cursor in the middle instead of my log in screen. The third time this happened I started pressing buttons on my keyboard. While I was fiddling with the F buttons, mainly F1 to F4, and the print screen, scroll lock, and pause/break buttons, my PC started working again, Why?

As for the actual issue... I have not seen this before. I have seen a blinking cursor on failed bootup located at the upper left corner, but not in the middle. I do wonder what version of Windows is on the computer? Knowing that might help one of the others here give you a bit of an answer.. I will be watching too as I am quite curious on this one!
You might send the link over to him by PM... :)
for some reason i suspect rootkit virus in his case, lots of those latelly
1) FP = False Positive. Sometimes when security software is set to maximum settings, it will cause it to report some non malware files as being potentially dangerous. The default settings for Webroot has several of the settings set a bit below maximum for this reason. My own experience with Webroot has been that even with all settings set to maximum I still do not have problems with False Positives.
2) Phising Filter settings in IE are usually in the Tools drop down, but as I run an older system I do not have IE 10. I am not sure where to locate it on that version.
3) Memory Leak is where a program fails to correctly clear and release memory used when no longer needed. This causes the RAM usage to grow much higher than what it should be, and can slow down computer performance. Do you remember the 'old days' of Windows 98 in which after a few hours of heavy computer usage it often would slow down to the point that it was hard to use, and it could be fixed by simply rebooting the computer? That was caused by memory leak. Several of us on here have found that the Webroot System Analyzer does detect memory leaks in our browser (IE on my system gives that warning in Webroot). It is not anything you have to worry about though, it will not hurt the computer.
4) As for that possible rootkit, chances are if you had one Webroot would have detected it. You can get help double checking though. If your copy is Best Buy Subscription Software, call them as Mendo suggested. If you purchased a non Best Buy version, your support comes directly from Webroot and you can Submit A Trouble Ticket for help.
Hope all of this helps.. have a great day and let us know if you have any problems!
I'm not saying this caused a problem for "Cloud" but is a good possibility! We will have to wait and see if it continues?
Looking over the logs myself, I see errors consistent with a video card problem, which would explain the intermittent black screen, particularly at bootup. You're getting a lot of errors like this one:
The AODDriver4.2 service failed to start due to the following error: ^^%%2
That driver is your ATI video card's driver.
I don't see anything bad jumping out at me from the logs. This looks like a video card issue to me. The agent possibly may have had something else in mind or thought you might appreciate a remote session, but it looks like from the conversation, he didn't see anything malicious either.
