Today something strange started happening.
I was playing Battlefield 1& the Origin client started to behave strangely. It wasn't syncing online. So i restarted the computer & when i logged in to an account, all of a sudden there was 10% cpu & 100% ram consumption on startup. The computer was literally hanged. I couldn't do anything. Even the task manager wasn't responding. I saw multiple rundll32 running in task manager.
Can anyone tell me what's the issue ?!
Should i reinstall OS ?
