With sophisticated ransomware attacks claiming more and more victims… you need to do everything you can to make sure you don’t get caught out.

Ransomware attacks, including:

  • WannaCry
  • ExPetr

… have been widely reported in the press. But how could ransomware affect you?

Ransomware can attack businesses, public sector organizations and home users. When it strikes, ransomware will often encrypt the files stored on the victim’s PC – so the victim can no longer access any of their data. Then the ransomware will demand that the victim pays a ransom… in exchange for having their encrypted files ‘unlocked’.

In many cases, a ransomware infection can spread to a user’s PC if the user:

  • Opens an infected email attachment
  • Clicks on an infected link
  • Installs an infected app – from a third-party app store
  • Visits a legitimate website that has been infected

How to defend your PC from ransomware

These simple steps will help you to protect your PC… and protect all the precious data stored on your PC:

Use your security software... to protect and detect

Kaspersky Anti-Virus, Kaspersky Internet Security and Kaspersky Total Security can all help you to protect your PC from ransomware.

If you already have Kaspersky Anti-Virus, Kaspersky Internet Security or Kaspersky Total Security installed on your PC, we recommend that you do the following:

  • Make sure System Watcher is always switched on. It’s an essential part of your defenses against ransomware – including new variants that criminals may be launching. In many cases, it can help you to reverse the damage done by malware. With System Watcher running on your PC, you’ve got protection against new variants of ransomware that have not yet been added to malware databases. Even if you’re attacked by a new variant, System Watcher will help to prevent your files being encrypted.
  • Manually run a full scan of your PC. If your Kaspersky Lab software detects a ransomware infection, you can delete the infection file and then reboot your PC.

Get the latest updates for your Windows operating system

Make sure you always install the latest Microsoft Windows software updates. Many of Microsoft’s updates fix specific security issues. If you don’t apply these updates, you could be leaving the door open for ransomware and other attacks to infect your PC.

Update all your applications

It’s not just the operating system that needs to be kept up to date. Other programs running on your PC could also compromise your security… if you fail to download the latest security patches & updates for each application you’ve got installed on your PC.

Kaspersky Internet Security and Kaspersky Total Security include Software Updater – which scans your PC’s software and helps you to install updates for a wide range of commonly used applications.

Backup your data… so you can safely store copies of your files

Get into the habit of regularly creating backups of all the files that you want to protect.

You should store your backups on external storage devices… and make sure those devices aren’t constantly connected to your PC.

If you want to save time and simplify the backup process, Kaspersky Total Security includes an automated backup feature.

Be careful what you click

It’s always a good idea to avoid opening suspicious emails & email attachments… steer clear of suspicious websites & web links… and be careful which apps you download.

Protect all your devices

Ransomware can affect all operating systems – not just Microsoft Windows – so it’s worthwhile taking sensible precautions and considering whether you should invest in security for every computer and mobile device you use.

Android phones and tablets are also popular targets for ransomware attacks. Kaspersky Internet Security for Android can help you to defend your Android phones and tablets against a vast array of malware – including ransomware.

What if you’ve already got a ransomware infection?

After an attack, you’ll need to review your security measures. Installing security software – with good anti-virus functionality – can help you to delete the ransomware… and help to ensure your device doesn’t become infected again in the future.

However, deleting the infection is unlikely to be enough to restore access to your ‘locked up’ data.

We’ve developed a range of decryption tools – and we don’t charge anything for you to use them. Even though we don’t have tools for every type of encryptor, it’s worth visiting noransom.kaspersky.com to see if we have a tool that can help you to decrypt your files.

Remember… there is nothing that can guarantee complete protection, so please exercise caution when you use your computers & mobile devices and whenever you’re online.
