You should never click “Yes” and especially not download/install anything suggested by the malicious “Your PC performance might be poor” pop-up.

However, “Your PC performance might be poor” removal might not end just there. In case your computer is infected with adware, you will also have to eliminate it to stop the unwanted activity on your machine, which may include the following symptoms:

Avoid the installation of potentially unwanted programs

The constantly occurring data breaches and new malware strains like Djvu ransomware became the epidemic of modern times. Despite the rising awareness of all the internet users, there are many that are unwilling to listen and protect themselves as required in order to prevent computer infections; in other cases, users simply lack basic computer skills to avoid unwanted programs and malware infiltration.

Installing comprehensive security software is not enough, however, and users need to always combine it with good online browsing practices. As previously mentioned, cybercriminals often employ social engineering to make users perform actions they otherwise would not, i.e., installing unwanted software on their machines.

To protect yourself from phishing attacks, never believe pop-ups and warning messages coming from various websites and claiming virus infections, data theft, and threatening with consequences. Only install software from trusted sources (avoid torrents) and always pick Advanced/Custom settings during the installation process of freeware/shareware to get rid of all the optional components before they manage to enter your PC.
