I am no longer recommending www.mspaintxp.com/ or their MS Paint XP software, as I just discovered that their download has recently been distributing Trojan Droppers. Luckily my computer isn't harmed from the discovery, as my antivirus software caught it before it could take effect.
The Terms and Conditions of the website also state that there is no guarantee that defects or imperfections to the software will ever be corrected, which means the dropper will most likely not be fixed. :\
This website used to be recommended for its easy-access, no-issue XP version, which I have downloaded multiple times over the years for new computers, but unfortunately that will have to come to an end. I am removing any mention of the website from the group to ensure that no one makes a similar accident.
I will continue to seek out different versions of MS Paint online and verify if they are safe. But in the meantime, I'm afraid you're all stuck with whatever version you have.
But if anyone knows a safe, alternative source, please share them with me.
