Ok, well when i got home today, i went on vindictus to farm some iron for my staff. Everything was normal untill i decided to go to the depot since i had left over nx, and my computer started to act odd. It would start to freeze and nothing would work right. I couldn't use any of the keys i normally use to exit out of windows, and when it stopped, it made this weird sound. The closest description i can think of using for the sound was like the sound you hear on vindictus when you pick up a potion from your inventory and set it back down and it makes a sort of sloshy clunk sound, but it sounded deeper. It was really odd. So i thought that it seemed like it might be some kind of virus or intrusion on my computer, and since none of my buttons worked even when it wasnt acting up, i pulled the plug on my computer. When i got back onto my computer all the websites that usually keep me logged in were all signed out. Everything signed back in okay, but to be safe, i changed my nexon password (since its really the only important thing i have on my computers, id be devastated if i lost my nexon account, but i wouldnt care if i lost my youtube, or mabi nation account, lol). I did a scan, but nothing came up. Now im kind of worried, because a few days ago my 1 year subscription to my antivirus ran out, and my mom said she will pick up another subscription tomorrow, but im still worried. Should i be concerned?
I would put a tl;dr down here, but if you really want to help me, you should read the whole thing.
Is there anything in particular that i can do to help my computer, or find out what it was that messed up my computer?:T_T:
