Ransomware has actually been a horror story for the last 4 years. It is hard to picture a more dangerous virus for both individual users and organizations. The algorithms used in MSIL/TrojanDownloader.Agent.GIW (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy actually exists, and possibly will exist. However, that virus does not do all these terrible things immediately – it may require up to several hours to cipher all of your documents. Thus, seeing the MSIL/TrojanDownloader.Agent.GIW detection is a clear signal that you need to begin the elimination procedure.

Where did I get the MSIL/TrojanDownloader.Agent.GIW?

General methods of MSIL/TrojanDownloader.Agent.GIW spreading are standard for all other ransomware variants. Those are one-day landing sites where users are offered to download the free app, so-called bait emails and hacktools. Bait emails are a pretty new strategy in malware distribution – you get the email that mimics some routine notifications about shipments or bank service conditions modifications. Within the e-mail, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly easy, however, still demands a lot of attention. Malware can hide in different places, and it is better to prevent it even before it gets into your PC than to depend on an anti-malware program. Common cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a computer remains on YouTube videos. That can save you a great deal of time and money which you would certainly spend while seeking a fixing guide.
