The biggest threat virus wise at the moment are ransomware viruses. I posted about this back in April 2015. You can read this article here.
The problem is getting bigger because now the criminals have entered the broad stream media via ads on prominent websites. Emails were the usual transport for this type of virus but now there is the potential to get infected simply by opening a website. You don’t have to click on anything within the website for the infection to occur. This is because the mechanism for infection already exist on the website when your browser integrates with it and the criminals are taking advantage of it.
In the story below from the Malwarebytes blog which is a premium product that defends you from, you guessed it Malicious Software they suggest using an adblocker. There is a free adblocker program called AdBlock Plus. Adblock Plus is the most popular adblocker available for Firefox, Chrome, Opera, Safari, Android and Internet Explorer. If you go to their website using any of the above browsers it will automatically select the right version for you. You simply download and install and the default settings are all you need and you’re good to go.
The other major thing you need to do to protect yourself is to make sure you have a current backup of your computer. But remember to disconnect your backup drive from your computer when finished because these ransomware viruses will infect any media (USB thumb dives and external hard drives), connected to the computer at the time of infection.

What is malvertising?
Malvertising, or malicious advertising, is the use of online advertising to distribute malware with little to no user interaction required. You could be researching business trends on a site like NYTimes.com and, without ever having clicked on an ad, be in trouble. A tiny piece of code hidden deep in the ad directs your computer to criminal servers. These servers catalog details about your computer and its location, and then select the “right” malware for you.
Malvertising purposefully targets legitimate websites with high traffic, instead of trying to trick people into visiting malicious sites. In the less than 10 years since it’s been on the scene, malvertising has impacted major websites with traffic in the hundreds of millions (if not billions), including Yahoo!, NYTimes.com, bbc.com, and AOL.
And the problem’s only getting worse. In 2015, Google disabled more than 780 million bad ads, a nearly 50% increase over 2014. According to RiskIQ, in just the first half of 2015, malvertising increased 260% compared against all of 2014.
