PLEASE HELP! I allowed Avast to do a "clean up" this week. That usually entailed a "scan" for viruses. NOT ANYMORE! My computer is really messed up! I just tried to delete Avast, and even though I hate to see ads, I think their Ad Blocker is messing up my PC. I just noticed that when I asked what I thought was FIREFOX a question, the answers were supplied by an entity called THLIOKNI. WTF is THAT?????? Seriously, what is happening to my relatively NEW PC--had to buy a new CPU in October of 2023. And I've always used Firefox. But WINDOWS 11 is the operating system on this PC, and it is NOT compatible with Firefox apparently! I'm an elderly woman and I cannot handle this stress! What I also noticed is that I read Substack writers and depend on them for accurate description of current political and social news, but now I can't access the "like" buttons on commentators. Is that a Substack issue (I don't think so!), or is it something to do with the Avast "clean up?" WHAT ON EARTH IS THLIOKNI and how the hell did that get on my computer? PLEASE ADVISE ASAP! And I sincerely hope a REAL PERSON reads this! I do not want a million responses from other readers at other times, I want to hear from a REAL PERSON! You have my e-mail address. Catherine O'Kelly
