Well… the answer could be yes! Opening a Zip file can bring viruses!
The very famous approach to send .exe file from one person to another through an email is to Zip it first, then email the resulting Zip, and then the receiver has to unzip at his end. That’s where the planning of hackers and spammers start to get materialized!
Why Spammers use Zip file to spread virus?
Some viruses spread by emailing copies of themselves to everyone in the contact lists of infected computers; this means that you can receive infected files even from people you know. Avoid downloading Zip files from untrusted web sites. Double check the From address. Faked emails may imply a friend's name, but have a different email address. To remove ZIP virus, you have to obtain a reputable malware removal tool and run a full scan. For this task, we recommend Reimage Intego or Malwarebytes. Of course, you can choose your preferred software as well. However, do not forget to update it first. Additionally, if malware blocks the program, check the instructions below.
Zip file contain collection of files inside it. Simply knowing that you have a Zip file doesn’t tell you what resides inside. You really need to unzip it to look at the files that have been compressed. Due to this, the contents of Zip file are always hidden and unclear. This is the reason why hackers hack Zip files to spread viruses. Most of the potential hackers can even hack encrypted Zip files and spread virus; wherein you try to extract password protected Zip files contents and use the files without having mere knowledge about hacking.
Zip as unclear mystery
It is easy to double click an email attachment or a file within Zip file without knowing what lies under the mask. This is how your computer gets infected with potential malware when you actively make the virus to run, without realizing the file being double clicked could contain a virus.
But you can’t get a virus just by double clicking on a Zip file, as double clicking a Zip file has a different story!
When you get a Zip as an email attachment, double clicking that compressed file will just open it. If the file is a real Zip and it contains a malware, your computer will not get infected by virus until and unless you try to execute virus contained files. For instance, just assume you have a Zip file containing executable files along with virus inside it, called virus.exe. Under such case, double clicking just a Zip file doesn’t bring virus, but double clicking virus.exe will cause you to get virus.
From one of the forum users,
Is it possible to get virus just by trying to uncompress the Zip? Can Zip extension be manipulated so it is not actually a Zip file but a virus?”
Well, it is already said in the above part that a Zip file can contain virus, and in fact it is a common way of putting malware into a compressed file and spread virus. But the error message in the above scenario is not a symptom of virus or malware, but it is a standard error that you may receive when the file is either corrupted or if it has been incompletely downloaded.
