In this article we want to help people understand what is msiexec.exe and how its name can be abused by computer viruses.

What is msiexec.exe?

Please read this! The msiexec.exe process is absolutely safe – as long as it is running from Windows’s directory. If it is not, the process is part of a malware threat that is trying to obfuscate itself by masquerading as a legitimate process.

If you are here now and reading this article, then you have for sure observed unusual behavior on your computer. Regardless if it is advertisements, excessive pop-up ads, random webpages or tabs or the worst case scenario: opening of the other browsers, other than the one you are using at the moment, and when you have no intentions to use them. Something is definitely wrong here,right?

This article will help you to clear out the problem and will show you what exactly has happened or is happening with your PC; how to remove the msiexec.exe Virus and what to do if the issue rises again.

 What’s going on?This is what everybody is wondering when their computer and its actions become something different.  The digital era we live in have allowed the digital inventions to take over most of the labor humans used to perform manually. This allows hackers and eases their work by taking advantage of our not so tech-savvy knowledge of computers, programs, etc. They are familiar with our thought process, the habits we have formed for using our devices and have made threats that attack us on a regular basis. Years ago a computer virus was just that: a malware. Now the word is not strong enough of a definition as there are many types and kinds of viruses out there. The goal of this article is to tell you about the msiexec.exe Virus. As much as some still consider it not to be a virus and even a legal software, the truth is that it is not — it is harmful.

the msiexec.exe Virus could be easily discovered by simply looking closely at the advertisements and pop-up ads on the websites you visit. Yes, it is always fun to get a good promo-ad about a discounted vacation on the Maldives islands, but you should always ask yourself if this really is coming from a legit company or is a trap? Well, if the advertisement looks skeptical in any way like flashing images and/or shifting content, or if it is simply asking you to click on it — “you’re one step closer to you dream place!”, kind of thing — then it is MOST LIKELY a bogus. The more you click on such ads, the more they will continue to appear and the only way you can save yourself from them is to totally erase the virus off your PC.

Another sign of the msiexec.exe Virus  is the so called “browser hijacker”. This is when you are doing work on your PC and all of the sudden random websites begin to open, or additional portals. The content these websites usually have is again something of the type of the ads already mentioned or even worse, highly inappropriate. This is as strong as the red flag could be to signalize you that something is definitely gotten into your PC and needs your immediate consideration and to be uninstalled. A delay of removing it will cause further harm to your files!

How is the msiexec.exe Virus distributed?

There are countless of ways for the msiexec.exe Virus to be distributed than we all know of. Infected e-mail messages are one of the most frequent way, such as the phishing e-mails  — they normally appear like any other regular e-mail you have received so far, but don’t have any text, or have changing and/or self-deleting content, or are simply flashing, or just being weird. Letters from your Spam box/folder is another very popular virus carrier thing, or via “software bundling”, which means that  you have downloaded a program and along with it you have unknowingly downloaded few other files that has the virus. If a hacker has determined that the malware needs to be spread, he/she will find a way to do it.

You are strongly advised to read carefully the removal guide attached below, familiarize yourself with the removal techniques and don’t be afraid to test them when the unusual PC behavior begins. It is only in your best interest to do so.
