Danger level 3

Possible Suspicious Activity

Users should know that any information displayed by the Possible Suspicious Activity warning message is false since the alert is shown not by the operating system, but probably by some threat the user accidentally installed. Therefore, we strongly advise against calling the mentioned telephone number. On the worst case scenario you could end up talking with scammers that may try to extort money from you or gain personal information, and so on. What we would propose instead is get rid of Possible Suspicious Activity fake alert as soon as possible and to guide you through this process we will display manual deletion instructions at the end of the article. However, before you scroll below, it might be a good idea to take a look at the rest of our report and get to know how such threats work or enter the system.

Possible Suspicious Activity warning message might tell the user his system detected an issue, which could cause “failure of the operating system.” To scare the user, even more, it may say all of his data on the computer could be lost as a result of the identified problem. After scaring the user, the pop-up should try to convince him solving the problem himself could do even more damage and the only way to get the system fixed is to call “Microsoft certified technicians.” Needless to say, the people you could be talking to if you decide to give them a call might be nothing more than scammers acting like the technical support specialists.

After listening to the user explaining what has happened, they would probably suggest a specific way to help with the occurred system problem. For instance, the scammers behind Possible Suspicious Activity fake alert may suggest you give them your computer’s password so that they could connect to it remotely and fix the issue for you. Since there is nothing wrong with the system instead of fixing it the hackers could install various malicious applications, for example, keyloggers to steal passwords of your banking account or other sensitive information, etc. On top of this, the user might be asked to pay for such services. Also, the scammers might suggest purchasing expensive security tools or other products alike.

Naturally, we do not think anything good could come from calling Possible Suspicious Activity pop-up creators and advise users not to fall for such lies. Often, it looks like the warning message came out of nowhere, but if you think it through you may remember there might have been suspicious activity even before the alert showed up. That is because in many cases these scams are related to some unreliable applications, for example, adware. Such threats may show suspicious advertising content or redirect the user to some unreliable web pages even before it takes the user to the particular website showing the fictitious pop-up. If you noticed such activities, it is possible you could have installed some untrustworthy program without even realizing it, for example, it might have been bundled with a tool you downloaded from a doubtful file-sharing site, torrents, and so on. In which case, we recommend checking the system just to be sure and remove the possible threats immediately.

The problem is this task might appear to be a little complicated as the pop-up may not allow you to close the browser; in some cases, it could even go full-screen.
