Right now there’s a very dangerous phishing scam being spread via instant messages on Instagram.
For years now study after study has shown that about 25% of all PCs worldwide operate without effective protection from viruses and hacking attacks.
Most of those vulnerable systems have antivirus software installed, but that software offers little protection because the owners fail to take steps to keep the malware definition files updated.

Question from Carolyn L: A convenience store not far from where we live recently closed and the owners sold all the equipment at auction.

Although Chitika never really gained a lot of traction against the ultra-popular Adsense, they did serve as a vital source of income for quite a few bloggers who were unable to take advantage of the Adsense program for whatever reason.
If you currently have Chitika ads running on your blog(s), I have some bad news for you: The service has been shut down, effective immediately.

That’s a wonderful feature, but it can lead to a problem… [Read more…]
