Why do I see “Firewall Warning” on my desktop?

“Firewall Warning” is a misleading pop up message which shouldn’t be taken for granted. No matter how trustworthy it looks, it has nothing to do with Microsoft and similar companies that are considered well known and reputable. It is just a false security warning which is generated by adware-type programs. Such programs can infiltrate your computer without any warning, so make sure you are careful when installing download managers, PDF creators, video streaming software and similar programs because they can be filled with optional components. Once they enter the system, they modify system settings, hijack web browsers and start causing fake ads. One of such ads is “Firewall Warning” pop-up notification that belongs to Tech Support Scam group of viruses. Their aim is to trick people into contacting the fake Tech support service which is a costly service that cannot fix your computer in any way. Please, do NOT fall for “Firewall Warning” virus and never call the number which is given in this alert. In this case, you should remove adware that is responsible for showing you with scam message. For that, use ReimageIntego.

WinPCAntivirus has detected that somebody is trying to transfer your private data via Internet. We strongly recommend you to block the attack immediately. Details of the attack: remote host transfer IP 97.216.34.74; remote user computer name ‘FORENSICS’

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
