Now click ProgramData
Once you are in Program Date folder then look for any suspicious files for folder which you never installed or not aware or which getting modified frequently and delete them.
Now go to drive C > users > your user name > AppData

Also go to Programs and Feature and uninstall any application which is of no use.

We should not have two antivirus programs installed in a PC as non of them will work due to conflict.
It is advisable to install only one antivirus program in a PC
You can go to Task Manager > Processes > and check which application is taking highest memory and CPU, you can right click on that application > End task
Now you can reboot your PC normally and check if everything is normal
You can also delete the cookies of your browser frequently
All the above steps will not only remove the virus / malware but also improve the PC performance.
