Some infected Canadian computers will lose internet access on Monday, according to an online security expert for software security company McAfee.

Robert Siciliano said about 9,000 Canadian-owned computers could be infected and lose access to websites when the FBI shuts down temporary servers used to stop a scam.

“Essentially their PCs will be banned from connecting to the internet. They will not be able to access email, social media, chat, and so forth. They will be incommunicado,” Siciliano explained.

Canadians can go to www.dcwg.org to check if their computers are infected and take appropriate measures.  

Overall, some 300,000 computers, most of them in the United States, Italy and India could be infected and lose their internet service.
