Hello,
For the past couple of days, my computer has been slower than usual and I would like to know if there is a way someone could help me check if there is a virus or not?
Thank you in advance,

Hello,

Install "Real Temp" or "Coretemp" to monitor the temperature of the computer.
See how high the temperature of the computer rises during use. It should not exceed 60 degrees Celsius. If possible, attach a screenshot of the software to the message.

~~

To check your computer for potential infections and to get a general state of the system:

Follow the FRST tutorial by clicking on this blue link. ( take the time to read carefully - everything is well explained there ).

Download and run the FRST scan,
Wait for the scan to finish, a message will indicate that the analysis is complete.

Three FRST reports will be generated:
  • FRST.txt
  • Shortcut.
  • Additionnal.txt


Send these 3 reports to the site https://pjjoint.malekal.com/ and reply with the 3 pjjoint links that lead to the reports here in a new response so that we can review them.

(The blue links lead to step-by-step explanatory tutorials, click on them for more precise instructions to follow).

You're welcome =)

To avoid viruses, you need to know how hackers go about infecting computers: How computer viruses are distributed

You can improve the protections and security of Windows by following these guidelines:

1) How to protect against malicious scripts on Windows

2) Windows Firewall: the right settings

3) ublock on your internet browser
