Hello there, I have had this strange virus following me and is attached to some program I have but I can't find it and neither can a few virus software programs I have paid for. It hides in bios it seems and now my computer won't read the bios I downloaded. When I down load the correct bios from the MSI site, I only get two files. I am using a different computer and have formatted a USB-Fat32 and use winrar to extract. Also something strange is that I can't get the reset on the board to work. I have the reset trigger wired correctly I think, because I already discovered it was wrong but it still doesn't work. Now my windows isn't allowing me to switch back to my administrator account. The screen freezes after I sign out as my regular account and the sign in screen doens't show up.
I bought this board at Memory Express, it was discounted because it was a return and the wifi isn't working. If It's junk, I only have a week to return it. PLEASE HELP!
I did get the Z490 to read the file and I did update the bios, or did I put a virus in instead? It's weird and I can't seem to reset the board. I know I will have to take out the memory and battery and disconnect power and let it sit to clean any code. Does anyone know of a way to speed up the process? Magnets? or some other method to clear it for certain and quick? I just hate taking it a part and don't want to do it again unless I can find some new information on this virus so I can rid it from my systems once and for all! Please help! Thanks in advance! JM

Hi
There is no way to get a virus into BIOS, unless it's modified.
Wipe the OS drive and start off with fresh installation.
Also what is the system spec? >>Posting Guide<<

If you think something has a virus, much less something that can get into the BIOS.....by moving memory sticks and files around all over the place you're probably just infecting your other computers as well.......Once you connect it, it's best to assume it has the virus on it as well. At least, if it has the ability to get into the BIOS, etc....

Lastly, if the wifi isn't working, I'd already be returning that board.......

Thanks guys, I put in some more time and unplugged it again including power to the board and even took the graphics card off and all wires. My cmos reset switch wasn't working and finally found the one on the board and now it's clean. It's easy to tell it's there because a short flash of a screen will go before the bios even starts, so it is in there. I've read and heard that even though it's supposed to be a solid form of code, it's on the fringes and can be, and indeed is, modified when the right amount of? current flips the numbers or "re-writes" the hard code when you flash. It's the flash that can be tricked somehow but it's really hard to find anything out about it online. I'm sure I'm not the only one with a boot virus in the bios. Come to think of it I remember a lot on the subject now and it's been a thing for a few years but it's easy to miss and perhaps I'm just very unlucky. Have a great day!
