“Ads by compareItApplication” Overview

WARNING! READERS BEWARE! Ads by compareItApplication also known as “Compare It” is a dangerous application categorized as adware. It will begin displaying several different kinds of messages that are however always one and the same thing – a trick aimed at making you install more adware. These tricks take as a front messages about missing plugins, updates on Java, FlashPlayer and many more legitimate programs, recommendations on video and download managers. The list goes on and on, there are even cases when Ads by compareItApplication will attempt to make itself look like an anti-virus program that recommends you to download its latest version to remove a malware you supposedly have.

  1. Remember – adware ask for your permission. They can not impose their will on your PC unless you let them. Simply ignore all messages you see and you should be fine until you remove the virus.
  2. Removing the malware can be both tedious and time-consuming, but you need to do it in haste, since this type becomes more dangerous the longer it holds on to your system. Ads by compareItApplication is well-known for reportedly collecting browsing information and passwords that it sends to whoever created it. In 2015, a lot of users have employed at least some form of online payment. If the virus steals the data from your PayPal account for example, it can be disastrous.
  3. A slowing down of the PC and some stuttering is closely associated with adware. This effect will be gone as soon as you get rid of the virus. Basically the advertisements put a strain on the CPU since they are not a part of the pages, but are generated by your PC, which then imposes them.
  4. Refrain from clicking on the ads if you can. They sometimes lead to unsafe sites filled with potentially unwanted applications and outright viruses. Even just browsing them is dangerous, so if you find yourself being sent there by one of Ads by compareItApplication’s  advertisements, immediately leave the page.


How To Avoid Ads by compareItApplication (And Other Malware)

The most famous way adware use to slither in systems is a duo of software methods. One is through what’s called a shell program. Basically when you are searching on the internet for some things – torrents or a crack for games most likely, maybe some MP3 files – there are programs that can track your search terms and rename itself accordingly. Many users do not realize what’s going on until it’s too late to do anything but remove the virus that latched onto their computers. Download anything only from websites that have been verified by your anti-virus program.

The second part of the duo is through real, free software, that is simply infected, because whoever created it received compensation for including adware in the bundle. The good thing with this is that there is always a sort of disclaimer at some point that you will be receiving advertisements. Here is an example:


Above you can clearly see the statement that tells you you will be receiving the business end of the stick. This probably happened with Ads by compareItApplication too. What these guys are relying on is that you will not be paying attention and you will just click next. And this is my point: always monitor each step of whatever you are installing.
