My laptop suddenly became really slow. My USB stick is not recognized and it all happened by chance when I downloaded something yesterday. How do I know if there's a virus? My anti-virus program expired a few weeks ago. It is not possible to purchase a new one and carry out a scan. Can you do something else to make sure you have a virus?
If it does not run then windows restarts then all viruses are gone.
It runs yes, everything works, but it is slow (it may be that it is not really so, you can also check it somehow (computer manager or something))
and reset everything, although I don't know if there's a virus is a real shame, I have a lot on my laptop
Maybe your hard drive is full. There are free antivir, avast or mcafee virus scanners that you can download and that check your system.
It can also run slowly without virus if you have full windows full everything runs slowly
Run Emsisoft Emergency Kit once. If something is on it it should be found.
Everything is clean. Nothing is fully painted, but as always
