Protecting Zip Files From Viruses

Your favorite compressed Zip files can face corruption due to many causes and virus attack is one of them. But the prevention can be taken, if you are wise enough to know the importance of these files and realize how the Zip recovery need can halt your work.

To prevent any requirement of Zip recovery, you can deploy the following acts and protect your zip files from viruses:

• Always maintain the protection and relevant updating of the system: The users must have the latest version of WinZip as these possess the security fixes and enhancements for better protection from vulnerable programs. This is also recommended that the system must be immune through the good anti-virus program, with the recent updates and the optimum features like scanning all the incoming mails, quarantine the affected files and giving the update facility. Use of Windows update feature can help you to catch the recent fixes, benefited by Microsoft for your particular Windows version.

• Be alert enough to recognize your file source: If you are receiving Zip file attachment from the source, you are unaware of, ignore it and never open such attachment. This can also happen that the files from the known source may create the corruption issue as the sender’s system may be infected with the virus which sends the copies of itself to all who are there in the contact list, without any intimation to the sender. Downloaded zip files from the untusted websites can also make the situation worse.

• Make Sure that the hidden file name extensions are disabled: If the feature ‘Hide extensions for known file types’ has been enabled, then it is quite possible that you may fail to judge out the actual nature of the file as in that case, there will no extension explanation of the particular file. The files having .exe (virus infected file are usually represented by .exe extension) as extension can appear harmless to you. So make sure that this creepy feature has not been enabled.

Those zip files which have got infected due to virus or from any cause will surely require zip repair, feasible through zip recovery applications. These Zip recovery software have the power to scan the corrupted files with the extensive algorithms and thus it results into effective consequences.

Stellar Phoenix Zip Recovery software stands as the master in this era. This Zip repair application has been designed with the unique technology and by great minds of data recovery industry. With the large scanning ability, this Zip recovery software avails you the most interactive user interface and the suitability to all Zip file versions.

‘Header Corrupt’ Messages in Zip

The Zip file header is the portion of the file which retains all the information about the file like the creation date, last modification date, file size, file type and so on. The corruption of this information can make whole of the file corrupt. So if you get ‘Header Corrupt’ like messages while attempting to extract the Zip archive, this is certainly due the header corruption.

Sometimes these types of error messages can also arise due to the corruption in self-extractors along with zip files, if the occurrence of this error message is frequent. If the file has been downloaded, then the errors due to the network problems can make the file corrupt. So downloading the file again will cure this issue.

But if you get stuck again with this error message, then probably this is due to the virus infection which can make other zip files also corrupt. Viruses like CIH, which make their target to the executable files like that of self-extracting Zip files using WinZip self-extractor, can make the file corrupt and may be indicated through these kinds of error messages.

The virus can infect the self-extractor through the unsafe download or by taking a journey to your system from any storage media. So don’t trust any unreliable source as this could be the home of CIH like viruses. An efficient virus scanner is thus recommended to be installed so as to avoid such situations.

And for curing the already corrupted Zip files, you can try out the available zip repair solutions. As the addressable tool to all the corruption issues, the Zip recovery tools do a scan of the corrupted file to make it usable. These tools are specifically called Zip recovery software.

‘Invalid Compressed data to inflate’ Zip Error

The corrupted zip archive is the decisive state to be handled by Zip recovery tool. The contributing corruption cases are virus attack, CRC errors, application faults and so on, while the signal of corruption is made through different error messages, which flash up during the attempt of unzipping the archive. One of such error message is:

“Invalid Compressed data to inflate”

Actually, deflation is the compression algorithm used to dense the files in Zip archive and used in many file versions of Zip. When you want to unzip the archive, it is inflated with the reverse procedure. The failure to do this due to corruption or some other reason like file version mismatch can give the stated error.

If the file is being attempted to extract in the same version as that of used in compression, then the archive may have got corrupted, whereas in the else case, this is nothing more than the incompatibility issue.

‘Unexpected end of archive’ Zip Error

After compressing the files in a single Zip file, in order to have effective delivery through mails or saving the hard drive space, is common among all users. The correct results while extracting the file reveals that the compression was successful and flaw-free. But what if the results don’t come as expected and the extraction stops, may be due to some corrupted files or in downloading case, the incomplete download.

This is one of the error message which shows that the zip file is corrupt and hence the extraction is quite impossible from usual means:

“Unexpected end of archive”

This is kind of shot to the users, who rely on these files for saving the large sized and important files. The CRC error may also be encountered along with. You can get this error message after downloading the file, after upgrading or downgrading the Windows file version or if the file was already lying on your system, then the virus attack could affect the file harshly, leading to corruption.

Thus if due to any cause, the extraction halts and the process doesn’t behave as expected, then the user’s first response is obviously to search out the cause and more importantly the cure i.e. Zip Recovery. You may several error messages whilst the process of extraction, like:

“Zip file structure invalid”

This can be the file header corruption issues. Each Zip file retains a local header apart from the data. This local header is responsible for holding the information of the file like comment, file name and file size. All the local file headers are stored in the central directory, which is located as the end of Zip file. Now if this information is corrupt, then the data of the file can’t be retrieved.
