Windows 10: Event 4625 keeps happening every day at (nearly) the same time

I was checking Event Viewer to keep track of some stuff and realized I've been having security audit failures every day since August 25th (there are no entries before this date). I remember doing a System Restore on the day before, which might explain why I don't have any older events in the security event log (not sure if they get erased by a System Restore?). I'm not sure if this problem started on the 25th or before that as I don't check Event Viewer very often, but I'm a bit confused since, from what I gathered after a bit of googling, this event seems related to a Windows Server issue that might happen when someone tries to log in/hack(?) into a server. My machine isn't running a server - it's my personal computer. Also, the account where this "failed log on attempt" happens is the default Windows 10 guest account that I don't even have activated on my machine. How is this possible? Here's the log, I'd really appreciate it if someone could explain it to me a little better:

My first concern was that this could be someone trying to hack into my computer, but I ran several malware/virus scans very recently and couldn't find any threat. My computer also seems to be working normally; I haven't run into any BSODs or anything particularly odd/suspicious. This Event always pops up in Event Viewer around 1 PM, and there are always two logon attempts with roughly 5 seconds between them. I don't understand a lot about tech stuff so this seems very scary and confusing to me. The only other "different" thing I did on the 24th/25th was that I accidentally enabled Windows 10's update to version 1903, then used the System Restore I mentioned before to stop it. There are still some leftover files from the unfinished 1903 update on my computer, and I'm wondering if I should actually update to 1903 to try and see if this issue can be fixed. I'd really appreciate any advice/help on this issue since this is all very intimidating and scary to me.

Two ESENT event errors happening several times a day??


Hi,
Since Nov. 15 I have seen two ESENT errors (Event 490 and Event 454) every day ... sometimes two or three times a day listed in my Event Viewer. I have googled the daylights out of it and still come up empty ... at least for my computer 'expertise' (meaning 'or lack of') ...lol.

For the record I am using an All-In-One HP Pavilion 23-g017c (x64) AMD A6-5200 APU w/Radeon HD Graphics, running Windows 10, Version 1607, version 14393.447, using the Edge Browser while utilizing Windows Firewall and Windows Defender as my major security programs.

Event 490 says: taskhostw (3324) WebCacheLocal: An attempt to open the file "C:\Users\harts\AppData\Local\Microsoft\Windows\WebCache\V01.log" for read / write access failed with system error 32 (0x00000020): "The process cannot access the file because it is being used by another process. ". The open file operation will fail with error -1032 (0xfffffbf8).


Event 454 says: taskhostw (3324) WebCacheLocal: Database recovery/restore failed with unexpected error -1032.

Both appear at the same time usually about 8-10 minutes after booting up and then anywhere between two to four hours later.

Any ideas or suggestions would be greatly appreciated.

Thanks and regards,

After doing a bit of research it appears that the WebCache is being corrupted. You might want to scan your PC with Malewarebytes Free to see if you've picked up a PUP. Here is where I found some info although you've probably already looked here:

MyPhone website not showing "All Day" calendar events.

Helder,

It happens with every "All Day" event (all my All Day events are recurring events). Normal, timed events are shown properly. The events are ONLY shown on the "List View." But not on Month or Day view.

Like I said, this is only on the My Phone site. It stores all the information properly because when I sync my phone it all comes in properly... so it must just be the way the MyPhone site displays the calendar.
