NavaShield

NavaShield is a rogue antivirus that is classified as malware and nagware.

Why It Sucks

 * 1) It's a rogue antivirus, which makes it a virus.
 * 2) Part of its payload is nonsensical. One example is when it abuses Microsoft’s TTS voice to say random things or even swear at the user.
 * 3) When installed, if you use the internet, it sets your homepage to porn sites.
 * 4) Certain versions of NavaShield expands an alert that says it's deleting the hard drive, and it keeps making a beep, such can come off annoying.
 * 5) After a week's time, it will begin to pester you into buying the full version. Thing is, the servers are apparently down as of 2013, so good luck trying to use your registration key!
 * 6) It blocks you from the task manager.
 * 7) The laugh of this software is really annoying.

Redeeming Qualities

 * 1) It can be easily removed using software like Malwarebytes.
