Pop-up alerts regarding viruses discovered on your system were generated, as a result of the riskware’s infiltration. Because of its intrusive and aggressive behavior, ad-supported software a.k.a. adware is often referred as riskware. However, in the matter of fake pop-up and virus alerts, ad-supported software is more dangerous than usual. It prompts the user to call fake numbers, and it can even trick him into giving away his banking credentials. If a pop-up alert promoting the 1-800-311-5943 number has interrupted your browsing activities, you should proceed towards scanning your system as soon as possible.
1-800-311-5943 Pop-Ups Distribution Method
As we already mentioned in the first paragraph, fake virus alerts are typically brought by adware. If you are already affected by an ad-supported extension or a browser hijacker, usually downloaded in bundled freeware installers, any of the following may have activated the scam:
- Clicking on random pop-up ads promoting rogue software products. Keep in mind that the 1-800-311-5943 pop-ups may have been provoked by a rogue anti-virus program. Rogue AV software usually imitates big AV software providers, including products by Microsoft, but it is not to be trusted.
- Landing on suspicious websites employed for phishing and other forms of social engineering. Avoid clicking on random pop-up windows, caused by unsafe redirects to predefined pages. Many interactive websites, such as pages for watching video content online, are ad-supported and generate annoying pop-up and pop-under windows, in-text ads, and banners.
- Using p2p file sharing platforms, torrents, .exe files. Even though peer-to-peer connections are usually deployed to spread malicious software, it is still possible that a corrupted torrent may have brought the 1-800-311-5943 pop-ups. Avoid downloading from unsafe sources. If you are suspicious about a particular .exe file, you can upload it on VirusTotal and make sure it is not infected.
1-800-311-5943 Pop-Ups Removal Options. Prevention Tips
Ad-supported extensions can be removed manually from the system and the browser. However, removing the particular piece generating the 1-800-311-5943 alerts may not be enough. To recover the system fully, scanning it via AV software is highly recommended. This is what malware researchers have concluded:
- Adware increases the system’s susceptibility to malware. Suspicious applications generate multiple pop-up windows. Interacting with them may link the user to compromised websites.
- Adware may temper with the Windows Registry and add new registry keys without the user’s knowledge. Also, the program may be designed to run automatically on every system reboot.
The conclusion is quite obvious – adware is not malicious but it is definitely crafted to harm the user’s machine, and often his credit card balance. To avoid being affected, and to minimize the outcomes of the suspicious intruder, be careful with freeware installations and stay away from scamming websites.
The STF team of researchers has compiled several easy-to-follow steps that should clean the system of adware traces. And don’t forget – prevention is the best security measure. In other words, AV software that runs in real time and immediately detects new threats, such as the 1-800-311-5943 scam, is the best guardian against malware of all kinds.
