Hi Berny, i have bad news. A virus or multiple have infected my pc and registry and somehow kaspersky security cloud became nonresponsive so i tried reinstalling it but the new one would not open. The explorer.exe takes a long time to work and crashes many times, also fles and apps on desktop take long time too. I used malwarebytes and detected a trojan virus in user/appdata/local/temp/unkis.vbs but i am positive there are more hence why i trust kaspersky security cloud. What should i do?
