I have a desktop PC and recently installed windows10 OS
Then when that was up and running I went to install an antivirus. I wasn't aware that Windows Defender was part of the package and so I went to look for an antivirus program.
I like Chome browser and read that Avast was the best option with this browser.
Now in the days of old, it was always a safe bet to go to download.com/CNET to download free programs as they could almost guarantee the stuff was clean. No I find out this is no longer true!
The first surprise was that Defender blocked my efforts to install Avast saying 'this is a malicious file' - so I went via this website to what I thought was Avast web page (still think it was) but ever since I downloaded Avast free version I have had nothing but problems!
The main issue has been that it has blocked all access to the Internet, then my PC doesn't boot up normally as it did before and it hangs midway and requires me to come back and press F1.
I have since uninstalled Avast but all the problems have remained behind. And I began to think it may be an infected file so I ran windows defender which didn't come up with anything, except those three items which were quarantined but were invisible so I don't know where abouts they are,or if I should worry about the warning pop ups I received.
I also ran Malwarebytes but it came up with nothing.
I don't know if I have a virus or not, but ever since I installed Avast my PC is is being prevented from connecting to the Internet so its rendered useless!
