I wrote this article to help you remove “Antivirus Detected Some Suspicious Activity”. This “Antivirus Detected Some Suspicious Activity” removal guide works for Chrome, Firefox and Internet Explorer.

Do you get redirected to a suspicious website which displays the “Antivirus Detected Some Suspicious Activity” alerts? If yes, we have bad news for you. Your machine is infected with an adware parasite and it is the one causing the redirects. The good news is that the “Antivirus Detected Some Suspicious Activity” warnings are fake. There is not suspicious activity detected on your PC. Your machine is just fine, not counting the adware you are hosting.

But don’t panic. This pest is removable. You could have been infected with a much more serious threat like a destructive Trojan horse or a greedy ransomware. If you take immediate actions, you would have no problem dealing with this unpleasant situation. Don’t waste time. As soon as you spot the “Antivirus Detected Some Suspicious Activity” alerts, accept the fact your PC is no longer infection-free and start looking for a way out. Find the adware that is causing this mess and delete it. Get rid of this plague as soon as possible. It brings along nothing but problems and headaches. Don’t let it. And don’t let yourself be fooled by it. Clean your computer now. The adware has no place in your system.

The page which displays the “Antivirus Detected Some Suspicious Activity” warnings is highly unreliable. Do not click on anything you see on it. It is entirely covered with pop-ups which must be avoided at all costs. The problem is, the site contains a malicious code which prevents you from leaving. The pop-ups state that if you click on them, you will be able to leave the page.

Unfortunately, this is not true. If you click, the site will enable the full-screen mode of your browser. Or, what is worse, it will download an infection on your PC. The only way to close your browser and leave this site is to use your Task Manager. Do it. Do not interact with the malicious page in any way. Do not click on anything. Also, whatever you do, do not call the numbers provided. If you do, you will contact the hackers behind the adware and they will find a way to steal your money.

After all, this is what they are after. They will either try to convince you to purchase some shady product or a fake anti-malware app, or they will force you to subscribe to unwanted services. These people are quite imaginative. They will find a way to get what they want. So, don’t make their job easier and use your Task Manager to close your browser and start a new session. However, as long as the adware remains on board, it won`t stop redirecting you to the same dodgy site. That’s why you must delete it for good. It also bombards you with tons of annoying advertisements on a daily basis which makes your online surfing even more difficult. Don’t put up with that. Use our removal guide below and clean your PC now!

The “Antivirus Detected Some Suspicious Activity” alerts appeared because of the adware but how did the adware get in? Did you download it intentionally? We don’t think so. And yet, here it is. The pest duped you into giving it permission to enter. It used tricks. One of the most commonly used ones is called freeware bundling. Be extra cautious when installing free programs off the web as you never know what else might be attached to them. The only way to find out is to opt for the Custom settings in the Setup Wizard. This way you will not only see all additionally attached apps but you will also be able to deselect each and every one of them. Do that. Such extras are usually infections. Remove them. Pay attention to what you allow to enter your system. Crooks pray for your carelessness. Don’t grant it.
