Remove Cosstminn Ad Virus (Uninstall Guide)

Let's get down to it: what is Cosstminn? What affect can it have on your computer? How does it get there in the first place? How you can avoid installing it? And, crucially, how do you get rid of it? Please use this guide to remove Cosstminn ads and any associated malware.

What exactly is Cosstminn?

Cosstminn is a software program created to show you adverts when you're browsing or working online. And whilst that in itself doesn't sound too bad – after all, we're exposed to advertising pretty much constantly in our daily lives – adware isn't just a form of Internet marketing, it can actually make your user experience a real pain in the behind when you're using your computer. Not only that but it could be causing you real harm too. We'll see how shortly.

Here's an example of an "Powered by Cosstminn" ad displayed on a web page:

Things Cosstminn can do:

• It is able to change your browser, your home page and your search engine so it can redirect your web searches to sites that the adware publisher wants you to visit. Often these are simply websites that are illegal or X rated.
• It may be packaged with spyware, which is just as nasty as it sounds. Spyware monitors your Internet usage so that it can a) customize the adverts it shows you to appeal to you, and b) in a worst case scenario it will install something called a keylogger on your machine which will monitor and record everything you type. Naturally many of our online interactions are personal – from emails to friends, colleagues or loved ones to bank information, passwords and log in details.
• In addition to this, all the extra components that Cosstminn adware (and possibly spyware) have installed on your machine, mean you may well find that your computer is running a whole lot slower than usual as the malware is ticking away behind the scenes and rigorously dialing home to tell the publisher what it has found out about you.

How did Cosstminn get on my PC?

In the majority of cases Costmin is packaged with freeware or shareware – for example, a TV show, some music or a game. This is how adware creators generate revenue that enables them to pay for the future development or distribution of their free programs. You may also be attacked by adware if you accidently visit a website that's been infected by it.

I want to protect myself against adware!

The best thing you can do to defend yourself against Cosstminn is to install decent anti-adware and anti-virus programs on your computer. You should also be selective about what you download and don’t get suckered in by dubious looking websites or programs that appear to be too good to be true!

Removing Cosstminn

Unfortunately Cosstminn is usually difficult to remove but if you have been targeted you need to run your anti-virus and anti-malware and they should spot and remove the adware. Run them twice or even three times to be sure however. If after rebooting your computer the adware is still appearing you will probably need to take your PC to a computer store or repair center and get it professionally cleaned by an IT expert.
