How To Recover Files Deleted By Virus Attacks


Virus attacks and malware programs are common culprits for data loss. You can use the Advanced Disk Recovery tool to retrieve data lost due to a virus attack. The data recovery tool restores deleted files, which is what the article is about.

Tip : According to AV-Test, over 350,000 new malware are created daily. This means the chances of you being the lucky one are very slim.

Therefore, if you think you can ditch the virus attack, chances are not that great. Whatever the case, if you lose data and are panicking over how to get it back – Advanced Disk Recovery is here to rescue you.

However, before we get into details and learn how to use the recovery software, let’s know about different viruses.

All Viruses Aren’t the Same

File-Infector Viruses

These viruses target executable files, such as .exe, .com, etc. These infected executables make the operating system unstable and are the reason for the BSOD error. In some cases, the file infecting virus can make accessing saved data impossible.

What to Do: When you suspect your system is infected by a file infecting virus, detach the virus-infected storage drive and connect it to a remote PC as a drive that does not have the operating system installed. After that, you can try recovering data using recovery software.

Macro Viruses

Found embedded in documents & spreadsheets, micro viruses spread when the user accesses the infected document.

What to do: To get rid of micro viruses, disable Visual Basic support in Office applications. However, using recovery software, you can fix the corrupted files.

Web Scripting Viruses

These viruses have the capacity to bypass browser security. They get installed on the system through a downloaded infected file or a malicious website. Moreover, web scripting viruses can upload data to a remote server.

What to do: To stop the infection caused by web scripting viruses, disconnect the PC from the network. Now, to restore the data, use a recovery tool. Also, format the infected drive before using the drive again.

Resident Viruses

This type of virus hides in RAM, allowing them to spread to other parts of the PC and infect data.

What to do: Data lost due to a resident virus is not always recoverable. However, if the resident virus has only blocked logical access to files by changing them, you can recover them.

Encrypt Viruses

This family of viruses consists of ransomware, which aims to encrypt data and block access.

What to do: Some encrypted viruses use weak algorithms, making decrypting and recovering data possible. However, if the encryption is flawless, you cannot decrypt it, meaning data recovery won’t be possible.
