I know where I got this virus from and it wasn’t porn. I was trying to download a torrent for a game and it gave me that virus. So all the people who say stop watching porn, not all of us are that silly lol
go grab ad aware and it will fix everyhting for you
Hello, I’ve been infected by MSA to the worst it gets in the passed, and I learned what the dll’s that were injected into most of the core files did, and I read msa’s source code via ollydbg32 (aka Assembly; or asm)and it got to the point where it was triggering BSoD errors on boot-up so I had a long chain of events to get rid of it. (this was 2 years ago) I got it once again today, and took me about 30 seconds to delete it, I know how this virus works, and where it tries to hide. *email me if you need any help: * BTW it will help if you download Teamviewer 5 (google it) it is a remote control type of thing so if you can’t figure out what to do, I can control you OS for a short period of time to remove it for you. P.S. I’m 13 so don’t curse xD

the file didn’t really “disappear”, more-so it went into hidden file mode (right click a file and hit properties, check the hidden file box), to view hidden files open up any folder, and hit tools>folder options, click the “view” tab, scroll down till u see show hidden files and folders, and all hidden files like the one that disappeared on your pc will show up. (unless they are OS files, there is a way to show these to but figure it out yourself.) ~~byebye~~
Got this beast a few hours ago, got a little bit leery, but my Virus prog. didn’t find anything. Then the IE started, I’m always using firefox… I asked a good friend, worried about this, he gave me this site, I followed the instructions and hope I killed it
Nothing in the Task-Manager, I’m going on to look after it next few hours, if it’s there again. Hope it will not appear…
Good thing that it wasn’t on my system for long time, only a few hours, and I deleted it from the Task Manager right after ”downloading”. I didn’t find most of the files that were named in the instructions, and think it hadn’t the time to infect whole areas of my system? Let’s hope this is the truth :,D
Greets from Germany.
The same for me. I only use Chrome and IE was starting itself today. I found a file msa.exe modified today in my system so I killed the process and deleted the file.
My antivirus didn’t see anything so i search “msa.exe” on the web (“google est ton ami” a french expression) and found this page. Others file indicated here are not present in my HD.
I hope I have stop the infection right in time…
Sorry for my bad english.
I found this virus on my system after installing a file called “flash_player.45243.exe” from a web site. The site said – you have an old version of flash player, please click here to upgrade. I spent almost one day to remove it completely!
Hey guys thats all well and good you found and deleted the programs and reg keys, but you are still missing the thing that slows every computer down.
I suggest EVERYONE check their TASK SCHEDULER and then tell me what you find.
