PUADlManager:Win32/InstallCore Virus

Written by Robert Bailey

PUADlManager:Win32/InstallCore detection is a sign that your PC is encountering an issue. All viruses are inherently dangerous, without any exceptions. The InstallCore unwanted program may not be classified as full-fledged malware.

PUADlManager:Win32/InstallCore corresponds to a program installer that aims at installing unwanted programs. It may be included in the installation package you’ve recently downloaded from a third-party website. Such a form of monetisation is widely used by users who crack programs. They receive a coin for each PUA installed, and you receive a PC filled with junk applications. Not the best trade-off, to say the least.

What is PUADlManager:Win32/InstallCore?

Alert of the PUADlManager:Win32/InstallCore you can see in the lower right corner is demonstrated to you by Microsoft Defender. That Antivirus is quite OK at scanning but prone to be generally unstable. It is vulnerable to malware invasions. It has a glitchy user interface and problematic malware-clearing capabilities. Thus, the pop-up about the InstallCore is just a notification that Defender has identified it. You will likely need to use another anti-malware program to remove it.

PUADlManager:Win32/InstallCore unwanted program is a typical example of PUA, which is pretty much widespread nowadays. Being free to use, it may provide you with “the extended features” for the extra payment. Some instances of this program type can have no real functionality whatsoever – just the shell with the bright interface. You can see it advertised as a system optimization software, driver updater, or torrent downloading tracker. This or another way, it does not provide you any true capability, exposing you to risk instead.

Is PUADlManager:Win32/InstallCore dangerous?

I have already mentioned that PUADlManager:Win32/InstallCore PUA is not as trustworthy as it plays to be. The “legit and helpful” app can unexpectedly unveil itself as a downloader trojan, spyware, backdoor, or coin miner malware. And you can never estimate what to look for even from separate instances of InstallCore unwanted program. That still does not say that you need to panic – probably, this nasty thing has not succeeded in doing bad things to your computer.

The exact damage to your system may be created not only because of the malware injection. A significant share of suspicious programs, like the InstallCore application is, is just improperly programmed. Potentially, their actions are rather useful than pointless if done on specific system configurations, but not on each one. That’s how an uncomplicated system optimization app can trigger chaos with constant BSODs on your system. Any interruptions to the system registry are unsafe and even more unsafe if performed with such programs.

How did I get this virus?

It is difficult to line the sources of malware on your PC. Nowadays, things are mixed, and distribution ways used by adware five years ago can be used by spyware nowadays. However, if we abstract from the exact distribution way and will think about why it has success, the explanation will be very simple – low level of cybersecurity knowledge. Individuals click on advertisements on odd sites, open the pop-ups they receive in their web browsers, and call “Microsoft tech support,” believing that the strange banner that says about malware is true. It is important to know what is legit – to prevent misconceptions when attempting to determine a virus.

Nowadays, there are two of the most extensive tactics of malware spreading – bait e-mails and injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to recognize a fake – the 2nd one is very easy to handle: just do not utilize cracked apps. Torrent trackers and various other sources of “free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway place of malware. And PUADlManager:Win32/InstallCore is just within them.
