Where did I get the RiskTool.Win32.Gamech.vho?

Those are one-day landing sites where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait e-mails are a pretty new method in malware spreading – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions updates. Inside of the e-mail, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks pretty easy, however, still demands a lot of focus.

Essential cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That can save you a great deal of time and money which you would spend while looking for a fix guide.
