They hacked Skype and released a lot of viruses, took action. What else to do?

Question

Skype

It all started a week ago somewhere, my antivirus (free) showed caught viruses, I could see the .ru site domains, and strange things came out to the temp folder. Strange pages were opened in the browser, the list of which was empty (although I have an adware blocker, so maybe it blocked the content of these strange pages, I don’t know) On Saturday, from my Skype, the hacker wrote to my contacts, asking me to borrow money. On Sunday, I couldn’t log into Skype with my password, I suspected hacking, I restored the password via mail (it’s strange, but they didn’t take it away, and I didn’t receive any warnings from Skype), I indicated a possible hacking as the reason, and it turned out that when I entered and I saw all this writing. Took measures:
1. Rebooted the router to change my ip.
2. I bought a paid antivirus, checked for viruses and removed them. It turned out not enough.
3. Installed malvarebit, checked everything again - caught more additional viruses, deleted everything again. Among the viruses were a trojan, a keylogger, and a loadmoney. In the browser, I cleaned up some kind of race8.
4. With the help of an antivirus, I transferred all passwords under their protection and cleared them from the browser.
5. The firewall built into the paid antivirus caught a gray private IP and blocked it.
6. I looked at the browser history, I did not find any information that the cracker was still climbing somewhere. And in the computer in the registers I found this: QueryName i.bandito.org, QueryName isatap.DSL-100HN-T1v4, data transfer in the background (BITS), QueryName mc-portal.mail.ru, QueryName ad.mail.ru, QueryName jim28.mail.ru . Translating: deleted successfully reserved space for "https://+:26143/. " Carefully, we can have viruses from there, don't go in! The ssl certificate for port 127.0.0.1:26143 has been deleted, etc.
7. I changed the password on Paypal, called and warned them about this situation, warned them through Skype letters and my mail. a photo warning for my friends to be more attentive to my info.Now
everything seems to be clean, no viruses or strange pages pop up in the browser, Skype works under my new password, but I'm still not calm, because I don't understand the whole essence of the process How did this happen so that with 100% probability you know how to protect yourself.Questions
:
How exactly was I hacked?Did they find out my password?Or didn’t even have to know it?
Do others know my passwords now?
Как думаете, оперировали с моего компа удаленно? Т е могли видеть все содержимое моего компа как я сама вижу смотря на экран? Или каким образом?
Хватит ли мне теперь платного антивируса, мальваребит, сохранения паролей в антивируснике и фаервола для защиты? Или еще чего нибудь надо? И какие опасности еще могли бы или могут меня поджидать?
Заранее спасибо откликнувшимся, т к не к кому обратиться, потому на форуме и пишу.

How they hacked is a good question, there can be many variations - starting with a flash drive / disk with a virus that you or other people could connect to a PC, maybe you went to the site and grabbed the virus there, where exactly it came from is unknown ... As a rule, free antiviruses do a poor job, although they create the appearance of their hectic work. Your passwords could have been stolen, you probably do not know how long these viruses have been sitting in your system, and the antivirus could simply not notice them (after all, how did they get on your computer). It is unlikely that your computer was controlled and files were downloaded (unless, of course, there was a direct tip that you have valuable documents stored) you will not be able to find out either ...
Sometimes, even good antiviruses do not provide 100% protection. Usually, if I understand that the computer was infected with viruses (and a lot like in your case), I just reinstall the OS, install the drive, install the antivirus, configure the OS and then you can already work.
Be careful in the network and I wish you no more viruses! All the best
