What happened to my Steam ??!?!?!?!?!?!?!?!??!?

[Raeshon]

Whenever I open Steam or a game, a notification pops out saying the there is a virus or potentially unwanted software, what happened?

[Cathulhu]

Do you have a screenshot of that notification?

Possibly an update to your windows has modified your security.
Go to Steam directory rightclick Steam and run as administrator, and add Steam to firewall >allow through and add to exceptions to AV.

Do one of those extremely annoying full virus scans that takes hours just to be safe. But do find out what program is alerting you about the virus and if its legit see if reinstalling it would work.

idk

Same problem here, man. I've been trying everything I've read or heard from people. Now I'm at the point, after uninstalling and reinstalling, that Windows is now telling me it is an unsupported app.

If anyone figures this out, please update

[Cathulhu]

That is an entirely different message. Don't hijack other people's threads. That is very rude.

[ChristOurLife]

do a MS offline scan
what is the location of the path dangerous (please do not share name part of path)
do you have protected folders on

umm no. As I said, I had the same message, the same virus message. Th rest was just my story of trying to fix it.

I'm getting the same error. Steam updated itself yesterday and since then it won't launch.

"steam.exe operation did not complete successfully because the file contains a virus or potentially unwanted software"

The 'steam.exe' executable file itself no longer has the steam logo icon associated with it, it's now a system icon.

Any luck finding a fix?

** EDIT ** I updated my antivirus and was then able to launch the steam executable, it started updating itself again, but is now stuck on 'updating steam information"

I cancelled the task in task manager, and cancelled any other steam client apps in task manager, then reran steam.exe and after doing that a few times, it finally started steam. There is a new file in the Steam folder called "Steam.exe.old" now though - so I'm not sure what happened.

That is Windows Defender acting up.

If that the case, either something corrupted, or OP downloading things from random sites, and got a virus, or something that causing problems, or Windows, or Windows defender need repair if not functioning correctly.
