Unfortunately, a tiny few of these installation requests are legitimate, but the best course of action if you are not 100% sure of what to do when such a popup occurs, is to gracefully shut down your system and restart it by pressing Ctrl + Alt + Del at the same time so as to activate the Windows Task Manager. When the Task Manager appears, you can restart the system by clicking the “Shut Down” tab and selecting “Restart” as shown below:

A Good Way to Permanently Fix the Malware Problem
So, I've finally concluded that the only way of really being safe from infection is to work from a user login id that is set up as being a "limited account" login id, which is explained in the following paragraph.
Windows provides two levels of privilege for login ids: 1.) "administrator" privilege, in which the user and the user's programs are allowed to perform all possible system modification or configuration operations (even dangerous or malicious ones), and 2.) "limited account" privilege, in which no system modification or configuration operations are allowed, though performing most ordinary operations are allowed, including surfing the web, reading email, using Microsoft Office and almost all other applications. But because "Limited account" login ids are inherently unable to install any software at all, malware installation is prevented as well.
For several years, I've established limited account login ids for clients with children or teens because they are extremely vulnerable to being tricked into installing malware, and these limited accounts have worked quite well. In fact, in some cases, their parents have also requested a limited account login id as a safety precaution. The adults use the limited account for ordinary work but can temporarily login to an administrative account if they need to install a new program, etc. This strategy has worked very well, though some malware can still install itself in a limited fashion. However, such limited-install software is simple to remove and can not damage the system as a whole
So, I’ve recently concluded that the best strategy for many people is to have an administrative login id that is used only for administrative work, and also to have a limited account login id used for all ordinary, everyday activity. In particular, if you tend to surf web sites outside of the main stream or are very uncertain about which action-requesting popups are legitimate, or you just want to be super safe, you might want to consider the dual login id strategy.
For brand new systems, it's fairly easy to establish both limited and administrative login ids. For older systems, conversion can be a little more involved, as usually the best thing to do is to add a new administrative account and change the existing login id to a limited account. However, the main complication for the conversion method is that many system files continue to be "owned" by the converted login id, and ownership of all of these files must be changed to fully secure the system.
Some Parting Advice
And lastly, never click on a web link in any email unless you are 100% certain that the link is safe. If you must visit the link, copy the link into the clipboard and then paste the link into the address bar of your browser, at which point you can look at where the link is really going, and decide whether the destination looks legitimate.Please feel free to call or email me for a free consultation concerning malware (or any other PC issue for that matter). I can successfully remove existing malware infections about 95% of the time without the need for a full system reinstall, and in the rest of the cases I can easily recover your data before reinstalling the OS, assuming your hard drive isn't crashed.
My fee is $40.00/hr for home users and $45.00/hr for businesses. Most cleanups take about 3 hours, though if you have a system that is heavily infected with malicious software or other very difficult issues, it may take additional time to clean the system. I have 14 years experience with PCs, 40 years total computer experience, including bachelor's and master's degrees in computer science.
Alternatively, be extremely wary of the big box stores "PC repair" departments. Since they have minimal knowledge, they are unable to remove most modern viruses, and thus claim that the system must have the OS freshly reinstalled, though this is completely untrue. They'll often charge an outrageous price for a retail copy of the OS for reinstallation, even though free OEM install disks are available from companies like Dell. They'll also wipe out your data by not copying it before wiping the hard drive, and they won't tell you that before hand. And finally, they won't reinstall the factory drivers after reinstalling the OS, leaving you with a crippled computer. And, believe me, this is a best-case scenario. The worst case I heard was a client who had a big box store lose her laptop! They talked her into accepting a used computer in lieu of the one they lost.
Also, note that there are a lot of wannabe PC "geeks" posting right now on Craigslist who are advertising inexpensive rates; people who think that they know how to repair PCs because they use one and have tinkered a bit. Look for someone who at least has enough professional commitment to have their own web site and their own business email address, as opposed to someone using a free email address and has no web site. Look for someone with long-standing business clients and business references.
Cheap rates and/or corporate big box stores may seem like a good idea, but remember that you usually get what you pay for! I'm the guy who people bring their computers to after someone else has messed them up, so why not skip that step and bring them to me first! You'll save money in the long run and save a lot of headaches as well. My work is guaranteed and I provide remote access to your computer after I work on it should any questions or issues arise afterwards.
