I've only just gotten note that someone wants me to do a blog for once.. so I guess I'll try.
I have noticed, that on some computers, when I run something like Trojan Killer, it detects Minecraft.exe as a virus, though many things say Minecraft is virus-free, I do not believe that. Roblox is neither virus-free either, and from what I saw is these two games carry these sorts of viruses (if you aren't careful):
-Cookies, like Zedo, DoubleClick, FastClick, CasaleMedia, (Roblox, Many others)
-Trojans, like Vundo,H, Agents, and XPack. (Minecraft, Roblox, Many others)
-Spyware, like Babylon Toolbar, MyWebSearch, Facemoods, and Freeze. (Roblox, Minecraft, Etc)
-Malware.. ((Roblox is foreveralone on this one))

What was detected when I played roblox throughout my life:
Babylon toolbar,
Virtumonde.dll,
Mywebsearch,
Facemoods.

What was detected when I still play minecraft EACHANDEVERYDAY:
Random cookies,
A trojan agent,
System Progressive Protection (where did this cut in?)
Babylon toolbar.

As we can see here, both games aren't virus free at all, and they still all carry viruses two and fro, but most of these viruses come from pirated versions of the games.

Minecraft has all of those pirated minecraft versions, and some of the versions have many different viruses or aren't even legit, some are just good, and the rest are just horrible. Minecraft does somewhat have to have some connection to a rogue, because I got a rogue from it, and thats strange, it must've been fixed though.

Roblox has all of its mighty spammers, those goo.gl guys, they aren't real. Although the spam seems real, it isn't. It bans you, and it hacks you. The spammers, from what I can tell, aren't eve people. They may be stolen accounts controlled by bots to spam on games that they can find within whatever person puts them in, I noticed they were bots because I PMed thousands of them and never got even one reply rather then "Hey, (link) for free tix!!" having the same exact reply over and over and over again.

Minecraft might be better.. It's fixing issues

Roblox isn't even stopping the spam, so I don't really like it.
But which IS better??
