I have recently purchased a new dell computer about a month ago and after closing my browser because of a strange pop up, I noticed my computer was running slower than usual so I decided to restart my computer.I initially thought of doing so in safe mode, but when I went to start Kaspersky, they said something about not all tools will work properly in safe mode. So i restarted it again normally and did a full scan with Kaspersky.
During the Kaspersky Full Scan, a loud noise was coming from my laptop. After the full scan however, the noise has not ceased. The scan came up negative for threats.
I guess I am just worried because I know noise coming from a laptop can be signs of the system being infected. Was the loud noise only because of the full scan? Am i being paranoid?
