Nova Scotia RCMP is warning public about an online scam that targets computer users and freezes their computer for a ransom in exchange for money.
"This type of pop-up goes far beyond being a nuisance and can actually harm your computer," said Cpl. Christian Hochhold of the RCMP technological unit.
Known as ransomware, the malicious software pops up on the users' computers and then dupes them into paying money to have the software removed.
Hochhold says that if you cannot access anything on the computer beyond the pop-up screen your computer is infected.
The malicious software firstly freezes access to the computer system and then demands for a ransom to be paid to the creator of the malware. In some cases, it has also been observed that the software installs itself on the computer and encrypts files on the hard drive which ultimately prevent the user from accessing thier own files.
The RCMP is asking people to not submit to the scammers' demands.
"Do not pay the scammers' ransom request. Be sure to frequently backup your important data in case your computer is infected and if it is, have it cleaned to remove any malware," suggests Hochhold.
To prevent ransomware attacks, police advise people to:
Have a proper firewall installed on your computer.
Ensure software such as anti-malware, web browser and operating system are up to date.
Be cautious of the websites you visit.
Don't open email attachments unless your trust the source.
Regularly scan your computer for malware.
It may be possible to remove the ransomware yourself following instructions in an online search but it might be necessary to have a professional look at your computer.
