Hi Hazel,
Im NOT a security expert,
but there is an entry for an alledged pendrive virus dated 2016
a really strange download file, same time as a Harry Potter one.
plus some other weird and wonderfull entries.
I would STRONGLY suggest you post in the am i infected sub-forum at BleepingComputers
(read the tutorial first),
note they do tend to be very busy

However
IM more concerned that your HDD might be failing, your restore points are not being created due to an I/O problem.
Please run chkdsk /r
and memtest86
RAM - Test with Memtest86+

Thanks very much. The laptop is on it's last legs. The new hard drive last year was a reconditioned one as this stupid Sony machine would only accept an identical size/type hard drive (long story). The Harry Potter downloads were photos from an image site linked from Warner Bros studio. Drive is quite full and far too much stuff on it. I might just reinstall. Also have a new (second hand) laptop on it's way as right mouse click has gone which is annoying. Not sure what the pendrive issue could be - I rarely use one, but regularly swap sd cards.

I also think the hard drive might be failing. Had no issues until the last week though. I really appreciate you taking the time, thanks. But would rather wipe and reinstall than try and find a virus lol. Or possibly restore from system image, run the tests again and see what's different. If I do have a virus then it seems that MSE isn't enough.

Will do the memtest and chkdsk /r though - RAM has been in about 5 years. Will have to leave it till tomorrow now.

Hey just thought about the pendrive thing in 2016! I had a horrendous Landlord who came in and I suspect had access to the Laptop. He was trying to illegally evict us and there was a court case going on - we got moved without it going to court in the end. Could it be spyware?

I ran Memtest for one pass and zero errors. Decided to reformat and install from last clean system image (done when new hard drive was put in last year). It is just Windows 7 updated to that point, no files or other programs. Ran sfc /scannow and all fine. Just doing Windows updates now. Not too many. I am not doing any optional ones just yet. There is an optional one KB4012218 I want to check out first. If all gets up and running I'll do disk check again.

Apparently it's a windows file used for network discovery and diagnostics. Hardware problem can affect it. So it could well be the drive. When I'm up and running will do disk check again. But am also leaving all the optional telemetry updates off this time in case it was anything to do with that.

Update. It seems something corrupted Windows. I decided to do a clean install and all is tickety-boo now. Gained a lot more storage space, it's running faster, hard drive is fine, have less programs on now.

SFC /scannow
Just left the above running while I took a break, got back and it must have finished. Which event log will I find the result in? Also, I went into command prompt as admin, but it said it didn't recognise the SFC command. I ran it from Run OK though. Is that right?
