Accordingly, PC users are advised to account for the possibility of an ongoing security even if these pop-ups stop on their own.

A Browser Intrusion Stopped at the Starting Line

The 'System infected: Fake Plugin Activity 2' notification is a feature of several major brands of PC security suites and displays itself after your security software blocking an attempt to attack your machine. Although a 'System infected: Fake Plugin Activity 2' notification always is associated with browser-based security issues, a 'System infected: Fake Plugin Activity 2' notification may occur for any major browser.

An unblocked attack related to a 'System infected: Fake Plugin Activity 2' notification may cause other issues, such as installing threatening software or PUPs. Common side effects seen with threatening or unwanted browser extensions include:

• Advertisements injected into Web pages arbitrarily.
• Redirected Web searches or hijacked search results.
• Excessive numbers of pop-ups being generated.

However, a 'System infected: Fake Plugin Activity 2' notification also may be blocking attacks with other consequences, such as attempts to install threatening software with specialized attack capabilities. In most cases, isolating and removing the browser add-on responsible for generating the 'System infected: Fake Plugin Activity 2' notification may solve all related security issues.

Getting Threat Activities Off Your Browser

Although 'System infected: Fake Plugin Activity 2' notification indicates that the relevant attack was blocked, the software responsible for the attack still may be active until other measures are taken. Many browser extensions of a malign or otherwise suspicious nature may be identifiable in your browser's add-on manager menu. Nonetheless, malware experts can verify that some of the most recent attacks associated with 'System infected: Fake Plugin Activity 2' notification also use disguised and hidden extensions. These extensions may not be visible from your browser's standard menus.

Since a 'System infected: Fake Plugin Activity 2' notification is part of an already-installed security program, you may wish to use that same software to disinfect your PC and remove the responsible add-on. Other safety steps malware experts recommend when dealing with browser security issues involve clearing your Web browser's cache of saved data, including, ideally, passwords. As an example, the often targeted Chrome browser offers such a feature through a sub-menu within its 'More Tools' option.
