Virusdefense.info – How Did I Get It?

The PUP and/or browser extension that support the “Virusdefense.info” domain usually get into your computer via third-party installers. They can sneak into your computer without your consent, by concealing themselves in freeware installations and bundled packages.
In these packages, additional components for installation are not always disclosed properly, and people get tricked into installing potentially unwanted programs such as those related to “Virusdefense.info”. Sometimes that can be avoided by clicking on the “Advanced” or “Custom” option in an installation setup to see what will be installed.
Other ways of getting infected are by opening spam emails and downloading e-mail attachments, or by clicking on various ads and banners containing malicious content.

Virusdefense.info – More About It

“Virusdefense.info” is a malicious domain of a fake tech support website. It has another variant as “Virusdefense.info/us”. It claims that your computer is infected with different forms of malware and viruses. It also claims to be able to remove them if call the phone number “1-866-848-6738”. You are supposed to say the security “error message” that keeps popping up “S1M457”.
The truth is that this may be the most expensive call in your life. It is definitely not free, and it will cost a lot of money per impulse. That is not the only reason you should NOT in any circumstances call the fake support number – the scammers that run the website, may also try to get you to tell them personal details and financial information using different tricky techniques.
