A pain in the butt.

That's what Newstalk 1010's Tech Expert Marc Saltzman is calling a computer malware issue that's affecting between 5,000-9,000 Canadians. He was on the Jerry Agar Show on Monday.

These computers have been having problems accessing the Internet after the FBI shut down temporary servers used to stop a scam.

Tens of thousands of others worldwide are also having issues logging on.

However, Saltzman says there's no need to panic. He recommends calling your Internet service provider for help and they'll likely send you a disc with software to fix the situation. You can also download an anti-malware program from a friend's computer and use a disc or USB stick to transfer it to yours to install it. A trusted site Saltzman recommends is: www.dns-ok.us to find safe programs.

Saltzman points out this shouldn't be news to those with infected comupters, underlining the FBI has been getting in touch with those who have infected computers. Even websites like Facebook and Google have had warning messages pop on their sites if they noticed your computer had an issue.

He underlines this is not anything like Y2K and in most cases there is a quick fix.
