Nowadays, there are a lot of ads we see all over the web, and unfortunately some of them can be infected. This means you should be very careful when clicking on an ad.

If you still don’t know what is a botnet, let’s find out. A botnet is created by a hacker who wants his malware to take over thousands of smart devices, like computers. And you may not even be aware that malware is already on your computer. Noticed your computer getting slower? Scan it for viruses, spyware and ransomware. Your computer may be used by crooks as part of an extensive botnet, unknowingly working to attack websites, steal passwords or credit card details.
What can you do to protect yourself and your computer? First, always change or update your passwords. For example, social networks ask users to change passwords from time to time in order to keep the account safe, but you don’t have to wait for reminders. Scan your computer with antivirus software regularly. You can also check your IP address with Botnet IP Status Lookup from SonicWall to see if there are any suspicions about it.

First, the hacker gets you to install a cryptominer on your computer. After that, your PC processing power is used to mine for cryptocurrencies, such as Bitcoins. This can significantly slow down your computer and your electric bill usually goes up fast. Сryptominers are very popular today, so you’ve got to be aware of these problems.
