Many internet users may be familiar with the panic that comes when a message appears on the screen saying a virus has infected your computer. Many internet users also do not realize that more often than not, those pop-ups are the beginnings of a popular scam.

In 2017, the federal Internet Crime Complaint Center (IC3) received 11,000 complaints related to tech support fraud. These scams come in all shapes and sizes, with con artists contacting people by phone, e-mail, pop-up messages and through search engines when people are trying to find legitimate computer help. The criminals often claim to be from well-known companies like Apple of Microsoft and say they detected malware on your computer. Inevitably, the communication ends with the scam artist asking you to pay for services you dont need, or that may actually be harmful to your device.

But one scam technique that has appeared on Googles Chrome internet browser may have users panicking that something dire has happened to their computer. These tech savvy scammers make your browser think it needs to save a file over and over, according to ArsTechnica. The browser cant keep up and becomes unresponsive, but only after a phony error message tells the user to call a fake tech support number. And Chrome may not be the only internet browser affected. Malwarebytes security researcher Jrme Segura tweeted that this screen-freezing scam also hit Firefox. ArsTechnica reports representatives from Google and Firefox say they are addressing the issue.

Remember nearly any legitimate tech support company will not contact you unsolicited, so you should never call these phone numbers.

There are other precautions to take to avoid becoming a victim, starting with the installation of ad-blocking software and making sure all software is up to date. If a so-called tech support company does contact you, be wary of any pressure to act quickly and never give remote access to your devices.

If a tech support scam does come your way, IC3 recommends shutting down the device immediately, ignoring any pop-ups telling you to do otherwise.

Whether or not you fall prey to a tech support scam, you should file a complaint with the IC3 and be as descriptive as possible, noting any phone numbers, names, websites and e-mail addresses used by the criminals. If you do get scammed, the Federal Trade Commission (FTC) says to get rid of any malware that you or the criminals may have installed. If you gave someone credit card information to order bogus services, let your credit card company know so they can reverse the charges.

The FTC also reports that following these scams that sell you unnecessary (and potentially harmful) services, you may get a call from someone asking if you were happy with the service. When you reply negatively, they offer a refund. They may even call to say the company is going out of business and offering refunds. Dont fall for it. They will want your credit card or bank information, saying its necessary to deposit the refund. If you get a call like this, hang up on them and report it to the FTC.

Earlier this year, several defendants that used high-pressure techniques to peddle unneeded tech support settled with the FTC. A court order required Inbound Call Experts, LLC (doing business as Advanced Tech Support) to give legitimate refunds on average of $277 to 36,830 people. The more than $10 million settlement also blocks the defendants from misleading consumers into thinking they have security problems on their computers.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
