No.
some anti virus programs never check at boot time.
others check some areas like, memory.
but no antivirus check for all files at startup.
Antivirus software protect computers from viruses and other general malware. There are two types of antivirus programs: manual and real-time. Manual antivirus programs have to be executed by the user in order to scan the computer. Real-time antivirus programs are of better use and provide more security due to the fact that they continously scan programs, memory in the RAM and any other programs that the user might execute during the time that it is active without having to be executed by the user. Antivirus programs use a specific algorithm called heuristics. When an antivirus program scans a computer, it checks the code or text in a file and then cross-matches the code with known viruses in a database. If an antivirus finds a match or a potential match, it flags that file as a virus/potential threat and notifies the user of the results. Antivirus software only protect the user from self-replicating programs like viruses or worms and do not remove Trojans, rootkits, spyware, keyloggers, etc (although newer antivirus programs now detect almost any threat). Get a good quality antivirus program like Norton 360, McAfee Antivirus Plus, or Comodo. Now get an anti-spyware program like Spyware Blaster or SpyBot: Search and Destroy. For further protection, get an anti-malware program like MalwareBytes.

Chlorine is added to water during the treatment process to kill bacteria, viruses, and other harmful microorganisms. It helps to disinfect the water and make it safe for drinking by reducing the risk of waterborne diseases.
Viruses evolve primarily when they replicate and undergo mutations during their replication process. This can occur in response to environmental pressures, such as host immune responses or antiviral treatments. Additionally, viruses can exchange genetic material with other viruses through reassortment or recombination, leading to significant evolutionary changes. Overall, the rapid replication rates and high mutation frequencies of viruses facilitate their evolutionary adaptability.
If you just want to try your antivirus program you can do this: go to http://www.eicar.org/anti_virus_test_file.htm download the file and your antivirus program should detect the file and no worries the virus test doesn´t do any damage to your system (read the text on the homepage if you don´t belive me) I hope i could help you and excuse me for my bad English (my mother language is German)
