This stupid LUA virus thing explained. - Garry's Mod

I know, alot of you people at Facepunch (#garrynewman) know about these LUA viruses spreading around and you're trying to get rid of them. Well, Im gonna explain what this so-called "LUA virus" is. NOTE: This text is from the old Gmod wiki. All credit to Garry Newman and the Facepunch workers :) --------------- There has been a flurry of something affectionately named Lua viruses, scripts that seem to take control of Garry’s Mod and not allow or force you to do certain things. Naturally this can be quite worrying. How did it get here? Who did this to me? Most importantly, did it infect something else on my computer? Luckily, unless you received the ‘virus’ from a bad Lua module, it is impossible for it to have infected other files in your computer. GMOD’s Lua engine does not allow the file I/O functions to write or read outside of the Garry’s Mod folder. Lua Viruses do not affect anything outside of Garry's Mod, unless it is using Binary Modules. Viruses by definition are files that can infect other files, of which is not the case with any malicious lua script we have seen so far. They will usually only rebind your keys or make you say things and possibly crash your game or the server you are on by spamming. Possible sources of a malicious lua script could be a from a bad server or an addon you downloaded, although the latter is more likely. Most of the time the script is written out of mere boredom or more commonly an attempt to ruin someone’s reputation. The lazy but completely fool-proof way to completely rid yourself of the malicious script is to completely delete your Garry’s Mod folder, which is generally located at C:\Program Files\Steam\steamapps\username\garrysmod. Delete the entire folder; the next time you start Garry’s Mod a fresh vanilla GMOD will be back in it’s place. (This is because Steam automatically uses files from .GCF files if the folders/files are missing) This can be quite an annoyance however as you may have downloaded many things you do not want to have to download again. An alternative would be to meticulously go through your lua folder in \garrysmod and check to see if there are any suspicious files laying around. VAC Bans from Lua Modules and Scripts This has been one of the most concerning issues ever since Lua was brought to Garry’s Mod. Some people say that VAC has been disabled completely, while others believe that even using an innocent Lua C++ module could possibly get you VAC banned. Let’s set the record straight. Lua scripts and Lua modules will not get you VAC Banned! This has been said multiple times, and people still haven’t gotten it yet. Some comments straight from Garry Newman himself.. Is VAC going to be enabled in GMod? It already is enabled. It has been since GMod launched. I’m VAC Banned – Why am I not banned from GMod? Apparently, VAC bans work on a game by game basis. You’ll only get banned from GMod if you cheat in GMod. (sv_cheats 1, you cant be banned from using that :P) But what about the music modules and all the other awesome Lua dlls! VAC is Valve Anti Cheat – not Valve Anti DLL. It bans for Cheats, not DLLs. ---------------- If you want to be protected from this sh!t, use these very useful antiviruses: [URL="AVG"]avg.com[/URL] [URL="Avast"]avast.com[/URL] [URL="Norton"]norton.com[/URL]

[QUOTE=SkyArmyNinja;43428865]Well, Im gonna explain what this so-called "LUA virus" is.[/quote] It would appear you aren't explaining anything if you're just copy pasting something from the garry's mod wiki for the hell of it. [QUOTE=SkyArmyNinja;43428865] If you want to be protected from this sh!t, use these very useful antiviruses: [URL="AVG"]avg.com[/URL] [URL="Avast"]avast.com[/URL] [URL="Norton"]norton.com[/URL][/QUOTE] What? Why are you even posting this here? I haven't even seen a Lua Virus in YEARS, and how could an antivirus defend you against an exploit in a game?

norton 360 claimed that youtube is a scam site involved in selling fake cars, So im fine with my microsoft security essentials. Anyways, there is not a single antivirus that can protect against these now non-existent lua viruses. antiviruses check to see what applications are doing, and since gmod cannot in anyway touch anything outside of its folder, a normal antivirus will do nothing here

I trust LUA viruses more than I trust Norton, because LUA viruses can't fuck up all of Windows.

Let me explain something: 1. LUA Viruses = You probably won't ever see one from this point (Hell, Gmod 12's release even) in time on. 2. Anti-Virus is about as helpful as a box of rocks to combating said Lua viruses. 3. The only person worried about said viruses was a new comer who had no idea that they weren't around anymore. 4. If you were talking about the folks referring to the exploiter who keeps exploiting servers, He's has nothing to do with LuaViruses. 5. You are an idiot. Edit: He's a SkyDoesMinecraft fan... (SkyArmy refers to his fanbase.)

You've also acted like you are the know all be all when it comes to eradicating a threat which is literally non-existent now. I need not speak more as I'm done with this now. *[QUOTE=SkyArmyNinja;43428578]What I'd do is get an anti virus (like AVG) and get rid of it.

Stop blowing numbers out your ass, stop acting like you have some knowledge of how "lua viruses" work, and stop acting like we shouldn't judge you on how retarded you act.

At this point I hope he is a troll, because if he is not, then... Anyways, the guy got enough of a verbal beating, just let the thread die And as to you OP: Learn some stuff, please. For the sake of our sanity and your future

He's obviously trolling guys. That or he's legitimately mentally handicapped.

I remember getting one of these awhile ago. I found a lua file in my data folder named something stupid and deleted it BAM problem solved.
