Comismasis.co.in Fake Alerts – Virus Removal Instructions

The step-by-step guide below will help you remove Comismasis.co.in from your browser.

By Andy Mulholland - Malware Researcher 3 Min Read

Comismasis.co.in is a website that shows bogus virus alerts and push notifications on your computer or mobile screen.

Pop-up ads can display push notifications outside of the browser, even when it's not being used. Many computer users may feel frustrated when their screens are inundated with a large number of advertisements.

It can be quite bothersome and intrusive, making it challenging to use your device as desired. Comismasis.co.in pop-ups frequently appear on your computer's notifications panel.

Pop-up malware can often deceive individuals by masquerading as genuine security software, such as an antivirus program. Typically, fake alerts are generated to induce panic and prompt immediate action.

They are hoping that you will click on the pop-up and make a payment to them, believing that it will eliminate the alleged “threat”. On the other hand, engaging with these pop-ups can result in more significant repercussions.

More about pop-up ads

The Comismasis.co.in pop-ups often attempt to deceive users by falsely claiming that their device is infected with malware. They then prompt users to install an antivirus product that supposedly helps combat malware.

Allow me to provide some clarification: the notifications are not genuine and there is no real malware present on the machine. This strategy is designed to persuade users to purchase a license for a security software, allowing cybercriminals to profit from the resulting affiliate sale.

Pop-ups can also display advertisements from gambling and dating websites as well. However, a potential concern could arise if a pop-up were to redirect the web browser to a malicious drive-by download, resulting in the system becoming infected with malware.

At times, you may encounter Comismasis.co.in pop-up ads and get redirected to misleading websites while surfing the internet.

It's possible that the issues you're experiencing are caused by adware on your device. Both of these problems have solutions, although one may require more effort than the other.


Please follow the instructions below to stop the constant stream of fake virus alerts from Comismasis.co.in on your computer screen.

Tips to keep your computer safe

As the saying goes:The biggest vulnerability is the person behind the screen

So, here are some tips and what you need to know in order to keep your device safe and malware-free in the long run.

Keep every software installed up to date

Make sure that all of the programs in your computer is up-to-date with the latest version released by the developer. The reason behind this is that these updates frequently tackle bugs and issues that malware actors often exploit.

The same goes for your computer's operating system, make sure Windows is up-to-date with the latest software update to prevent malware from exploiting a hidden vulnerability.

Avoid downloading files from unknown sources

One of the biggest sources of malware infection in a computer system is third-party installations. This happens when a user downloads a certain program from sources that are not the official download links. Some of the common types of sources where malware is present are torrent files, cracked software, and games.

Be careful with opening email attachments

Malware often disguises itself as resumes and quotations and threat actors often send thousands of these infected emails to company employees around the world in order to infiltrate their network.

Always check where your emails are coming from as there may be a chance that the project attachment you received via email did not actually come from a co-worker.

Do not visit unreputable websites

Avoid visiting websites that contain unfiltered advertisements such as illegal streaming websites, cracked software platforms, and links sent out to you by somebody you do not trust.

These sites are often linked to redirect chains that load once you click on an ad element on the page. Following this chain often leads to drive-by malware and phishing pages that an average user may eventually fail to notice.
