The computer program known as PUA:Win32/ICBundler is a detector for malicious software that seeks to take control of both the system and the internet browser. This detection by Microsoft Windows Security includes stand-alone viruses and browser extensions that are often installed on a computer without the user’s consent.

It usually happens that PUA:Win32/ICBundler shows up on the computer by accident. Typically, harmful software or shareware has it embedded. After this virus becomes active on the computer, it may do a variety of things that can irritate the user. When it detects that the web user is surfing the internet, it often shows pop-up ads and redirects.

How does it infect the computer?

Malicious software bundles may allow PUA:Win32/ICBundler to infect the computer. It could be included with shareware or freeware. This danger sometimes comes with a serial key generator or software that has been downloaded illegally from websites.

Remember that in order to propagate their virus, attackers these days also depend on an advertising effort. For instance, PUA:Win32/ICBundler may be combined with phony software upgrades, and it may employ pushy pop-up ads to get users to download them.

Upon execution, PUA:Win32/ICBundler puts the payload on the computer right away. If the payload is a browser extension, the script is incorporated into Microsoft Edge, Mozilla Firefox, or Google Chrome without the user’s permission.

How does this malware operate?

Cybercriminals created PUA:Win32/ICBundler in order to covertly install a potentially unwanted application (PUA) on the compromised computer. A malicious program with a specific purpose, such as a rogue security tool or system optimizer, might be the cause. Malicious browser extensions have also been identified as PUA:Win32/ICBundler in some instances. In any case, the goal of this virus is to trick victims into paying money by offering them a product or an online customer care service.


A computer infected with PUA:Win32/ICBundler may reveal certain signs of infection. One is the installation of unwanted program that users didn’t recall of installing. Another is the browser redirect and search hijacking that occur when internet users are online. In addition, aggressive pop-up advertisements will flood the browser with irrelevant and suspicious links.
