WARNING – UPDATE:2/9 – OK The original post is not quite right. Original:
The AvaStar people (wrong – wasn’t reading closed enough) have posted a warning about recent downloads of AvaStar being infected with a Trojan or computer virus. They aren’t clear on what it was just that it was a bad thing. See: AvaStar – infected download.
If you downloaded their version 2.3-2 update in the last 2 or 3 weeks… you are at risk. Get a new copy and replace it. Scan your computer… Type DEFENDER in the ‘Ask me anything‘ or Search Windows field and run Windows Defender. Click Virus & threat protection. In place of a Quick Scan choose Custom Scan and point Defender to the place you keep your downloads.
Gaia commented below. Also, the original warning came from Casper Tech, not Machinimatrix. Also, the Casper Tech post has changed since I first read it.
Gaia and the Machinimatrix people seriously doubt the AvaStar code or package was infected.
Thinking about it, the programming code for Blender is Python. Blender add-ons, at least all those I have, are delivered as text files written in the Python language. So, the malicious code would have to be written in Python making it a specialized case, which is outside the normal pattern of malicious code for a web hack. So, I suspect Gaia and crew are right, the AvaStar programs and package were NOT compromised.
Doing some research this morning, I find that it is possible to embed malicious software in Blender files (.blend) and place executable code (.exe) in Python programs, but the Python has to call them and Windows intercepts the call and asks if it is OK to run it. Neither case is conducive to hackers. So, possible but unlikely.
However, Casper Tech is pointing out that the website hacks were sending people to a third-party site. They were attempting to inject malicious software into computers arriving at the site. But, a manual virus-scan of your computer will reveal any problem.
