OK, I don't see how that's possible. With that said, I cheat and use "Photoshop Elements", which is a freestanding program, not the Adobe subscription model. I have no trouble reaching the under 1 meg.target, even with images from high resolution DSLRs.
If the image you tried to upload was a screenshot from Windows. I'm guessing that Windows will only allow a full screen capture. I use a free version of "Screen Hunter", which allows the user to select only the area desired, thus yielding smaller files.I think Windows will allow capture as "TIFF" files, which are huge
But enough about me.
Thus far, you haven't been disposed of telling us which version of Windows you're using. My semi-educated guess is Windows 10..And I'm going to proceed on that assumption
Disclaimer, I know Jack squat about Win 10. But, that's not going to deter me, from claiming the right of, :"fools to rush in where angels fear to tread"..
First off, early versions of "Windows Defender" were pretty much either a hoax or a cruel joke. As of Win 10, Defender receives very good ratings. My point being, you may not even need Norton on the machine.
Most AV solutions need special tools to remove them from their publisher, as they deeply embed themselves in the Windows kernel. The simple add/remove programs function may not be sufficient to get rid of it completely.
Anecdotally, I had a similar issue on an XP machine, which, "cleared itself", after a major AVG update.
There is a small chance that the memory cell is bad. Please note that IDK how many memory errors the machine's firmware will allow before it fails to POST.
A simple program "MemTest86", will scan the entire memory block for errors.
Also, Windows files.are hidden by default. You may have to logon as administrator to access them.
@Kshipper Please feel free to jump in and correct anything you feel I've misspoken about.
