Last night I noticed a new icon/shortcut on the home PC for a program called Registry Mechanic (from PCtools). I did some googling, and while it seems like it may be a [somewhat] legit program & company, it also appears as though many people, over the last few years, have complained that this program mysteriously appears/downloads onto their PC. That is what may have happened on ours as well. The other problem others are experiencing, as I found out first-hand, is that it is very hard to uninstall. I went to control panel>add/remove programs>remove Registry Mechanic, and I keep getting a window popping up with an error that I'm unable to uninstall it. I forget exactly what the message said, but basically it said something to the effect of "program is not installed," or "unable to run program." 😕 I even tried to uninstall it using CCCleaner becuase it has a program remover/uninstaller, but I got the same message.
Last night I ran a full-scan using Malwarebytes, and I left it to run while I went to bed. I forgot to check it this morning to see if it picked up anything. 🤦 The quick-scan found nothing.
One suggestion that I read, and tried, was to press ctrl/alt/del and see what processes were running, and to stop any process that had to do with Registry Mechanic (RM). Then try to uninstall it. I stopped one and tried to uninstall it with no luck....perhaps there were other processess? There were other suggestion that involved going into the registry and deleting any line having to do with Registry Mechanic, or having the line "RM" in it (and NOTHING else). Like I said, it seems like this is a legit program, but what I've seen others mention is that not only does it seem to d/l on its own, but the catch is when you go to use it and "fix" any problems, you have to upgrade/purchase the full program. I've seen posts on this, during my googling, going back 5 years or so.
