Laptop behaving peculiarly

[studencik]

Hi, I have msi U270 with 8GB ram, Radeon 6310, SSD crucisal 250GB,
I had some problem with my laptop on windows, so I decided definitely to move to linux and buy SSD disk.
On start laptop was working very well, but after about month some problem starts making me crazy.
First situation is when windows in linux stop being able to close, minimize and scroll, but everything else is working well.
I know it because I can close windows by alt+f4 open terminal or applications by keyboard, but mouse clicking changed nothing.
Second very flustrating situation is during surfing the internet. Casual pages are going good, but facebook or for example google document are going so slow, that is just impossible.
Last thing happened today. I started my laptop and suddenly clicking was every one second on screen and I couldn't stop it, so a restarted my laptop and situation i happened again and again.

After this I am thinking I have to have some malicious software, but I thought it's impossible to have it on linux.
It it is possible to have mallicious software on linux lite, please tell me how to deal with it, because it starts going me crazy.

Have you opened the Install Drivers tool (Menu, Settings, Install Drivers), gone to the Additional Drivers tab, and selected a different display driver?  For you, you'll most likely have the option to choose the fglrx-driver for your Radeon HD 6310 graphics card.

This is probably unrelated however it might give you some perspective. I had slow browser loading of pages when my deluge program is downloading a program. Sometimes if you unselected DHT from the preferences it clears that up.

As for searching video drivers I believe that won't work unless you have the proprietor drivers installed first  I just click that and it says I don't have any until I actually install one from the AMD website.

However I only experience what you're going through when I have my Torrent program working without the DHT selected and I have DSL. I don't know if that could affect other computers browsing ability if their on the same LAN.

You say you suspect you have malicious virus problem in windows. What I would do is sign into windows and download the free Malwarebytes program and search for viruses and remove them. Clear, if you have not already done so, your browsers. Then sign into Linux and download and set up COMODO for Linux. You might have to work at setting it up However it is pretty much self explanatory. Reboot and clear your browsers again and this should speed up your system.
Sadly in this day and age nothing is immune from viruses or malware although you have an, and don`t quote me on this, only about a 15% chance of getting infected on Linux do to the large number of distros and the many developer eyes
that are constantly looking and testing software plus there are security updates and generally much more responsive attention than you will ever find on Microsoft, which I left several years ago. It seems lately even their patches are screwed up and tend to screw systems up particularly in office. Merry Christmas and Happy New Year.

Personally I don't think that there is anything related t viruses.
Have you tried looking into system running to check what processes eating much resources?
Or trying running single tasks to figure out which one makes the system slow response.

When I used Microsoft some years ago I actually had a virus that slowed down my system. I installed Malwarebytes and removed it. It worked for me, also my granddaughters laptop was running real slow and I advised her to download a free Malwarebytes and it showed she had over 400 viruses and trojans which she removed for free. Laptop ran like a brand new one after that. Not bad for free. Anyway, my two cents. What the heck it`s worth a try.
