It is dangerous to use a personal computer without an anti-virus program. But at the same time, no antivirus can guarantee that the computer will be completely protected from malicious software. Nevertheless, a virus can be detected without an antivirus.

Step 1
The presence of a virus can be indicated primarily by obvious signs. For example, strange messages pop up on the screen or unsolicited web pages open. Clear manifestations of the presence of a virus can be encountered if a Trojan program has settled on a computer.
Step 2
In addition, the fact that the PC is infected can be guessed by hidden signs. That is, viruses themselves are inconspicuous, and you can find out about their presence if you look in the registry.
Step 3
In addition, there are indirect signs of the presence of malicious software. This category of "symptoms" includes a sudden freeze of a running program, the appearance of an unknown error message on the screen, and other manifestations.
Step 4
To find a virus without an antivirus, press the key combination Shift + Ctrl + Esc or Alt + Ctrl + Delete: the task manager will start on the screen (it has four columns). Look at the contents of the first column - "Review name": here you will see information about the ongoing suspicious or unsuspicious processes. Each PC user has a different set of basic processes, so make sure there are no dubious ones among the additional operations.
Step 5
It is not uncommon for viruses to end up at startup. To find the startup files, open the Start menu, then click on the All Programs tab and select Startup. You can also find malware using the Ccleaner or Auslogics software.
Step 6
Open the system utility msconfig.exe: to do this, click "Start", then click on the "Run" tab, and then write the name of the application being opened. There is also a tab "Services", which contains those system components that start when you turn on the personal computer. This list may also contain malware.
