Solved Keyboard auto types slashes especially after keys 2, w, s, x

Its a HP pavilion 15 My keyboard is autotyping endless slashes especially after 2,w,s,x. I have to press any other key to stop it. But yet it happens. Is very annoying. First I thought they problem is in slash key, so I tried removing it, cleaning it and placing it. But it didn't work. Then realised its happening mostly when the above specific keys are used. My virus protection 360 security detects no malware. Trying a full scan on Windows defender. I will also try AVG after this. I have no clue what to do. Please help :( Is it possible that it is a hardware problem? My laptop is quite old, almost 5 years now. How much will keyboard replacement cost approximately? Also, I am not that great technically so you can imagine how helpless I must be feeling. Would really appreciate some help :( message edited by Disha_p94
