The Adobe update to my computer installed malware on my system.
A few days after I did a regular Microsoft security update, a dialog box popped up to tell me that "the security update" had installed McAfee Security Scan Plus which would do a "security scan" of my computer. I thought, "Really? Microsoft is giving away a free McAfee virus scanner with updates? That's a pretty impressive addition to the operating system."
It wasn't a virus scanner. Security Scan Plus is a malware program that checks if you have the entire McAfee security suite installed. If you don't then it gives you a big scary warning message "COMPUTER AT RISK" and tells you to fix it right away. I didn't push the button that said I want to "fix" my non-existent security problem, but I'll bet that if I had, it would have sent me to the McAfee sales web site. This program is malware because it is of zero value for the customer; it is nothing but an advertisement for McAfee.
I was pretty angry that Microsoft had installed this malware on my system as part of a security update, but apparently, it wasn't Microsoft. Just before I did the Microsoft update, I did an update to Firefox, and the Firefox update recommend I do an Adobe update. So I did. According to this web page, there was a check box in the Adobe update that installed the McAfee malware. It must have been checked by default, because I did not chose to install it.
So here's the scoop: Adobe and McAfee are installing malware as part of an Adobe "update". I wonder how much Adobe was paid to risk their corporate reputation on this. I also wonder why a security company like McAfee is willing to advertise via malware. They have to know that a lot of security-conscious people will never use their software again. I know I won't.
I also would like to say that I'll stop using Adobe products, but I already avoid them as much as possible because they have have a history of disrespecting their customers. McAfee didn't have that reputation before, but they will now.
