Smartnewtab Virus – how does it work?

As we said you will be dealing with Browser Hijacker. This type of viruses are characteristically going to put you through a lot of advertisements – pop-ups, pop-unders, banner or even whole pages filled with Ads (short for advertisements). You can also expect a heavy dose of browser redirects. What we mean by that? When you try to open a certain web address in addition to it or instead of it another websites opens up in a new tab or in a new windows. You should stay clear off of both the ads and the websites you have been redirected to as any interaction with them increases greatly the chance that more malware is headed your way.

Smartnewtab Virus – how were you infected?

Malware spreading is an advanced practice and over time a plethora of different approaches have been developed and tried. We will list the most popular ones along with some tips on how to avoid them.

  • Any time you receive a new e-mail in your inbox with an attachment in it you should be wary. Even if it is from a supposedly legitimate sender, maybe even a well-known company or your gas/phone/electricity provider. You should always check the files before downloading them (most mail clients have built-in scanners) and once again before actually opening them.
  • If you are downloading from web-sharing websites or you are a fan of p2p (torrents) then you should be always careful what files are actually being downloaded onto your computer. If possible check the trust-level of the uploader first, although that is far from being a reliable barometer, and always scan the files before opening them. Especially in the case of .exe files, you just don’t know if that is not a malicious application disguised as something else.
  • Software bundles. The most likely scenario in which you ended up with Smartnewtab Virus. In other words the inclusion of additional programs inside the installer of a program or any type of software actually, that you decided to install. Mostly the program would be a free one and the only way for you to prevent this if you select advanced installation options and carefully review and untick anything that might be different from your initial selection.

Before starting with Step 1 of our removal guide take the time to read this as it will spare you some questions that might pop-up during the removal process. The important thing to understand and remember is there are different “versions” of Smartnewtab Virus floating around the web space.
