About virus


Category: Ransomware

Damage Level: High

Distribution: Low virus, seen as a browser locker, is actually a computer virus infection that seeks potential system vulnerabilities to invade Windows sytem with the help of trojans.

Once infiltrates, this virus will automatically open your web browser and show a full window locker page as shown in below picture:



Be aware that this infection has nothing different from previous web browser blocked viruses, also categorized ransomware, but easier to handle compared with conventional ransomware infections.

This virus popup is built based on CSS or java scripts to only block your web browser for scams. Remember this lock page has nothing to do with any legal agency as it shows, under no circumstances should you pay the bogus fine to unlock. Not to mention that there is no guarantee that your payment will return the system in use as usual as before.


To handle this seemingly scary infection, you can just reset your web browser and use some security tool to scan out any hidden trojans or other related infections. However, the situation would be totally the opposite if the same lock page locks your entire PC system, then you need to try repairing your system using this conventional ransomware removal guide.
