One of my friends told me that if telegram chat is left open ; hackers can attack using telegram. Is it true?
In fact, it's impossible, but I advice to check which ports are closed and which ones are open. Find information about it in the search.
I think that you need to track the history of visits at least a week. I can advise you to download a mini antivirus, for example, Dr.Web CureIt or Kaspersky Virus Removal Tool (it helped me get rid of a virus that did not see the base antivirus). In addition, install a known basic antivirus, in which there is protection against phishing. And more, use the Chrome WEb Defender plugin (warns you about going to the phishing website).
