Hi, I've recently wanted to update my Windows because I kept getting the message. When I clicked to update Windows, it took forever and it didn't install the updates at all. Instead, it led to installing some suspicious programs, supposed anti-malware programs and even some suspicious browsers. I remember that one of the browsers seemed to be like a re-skin of Chrome, though I don't remember the name. And why would a Windows update install Opera browser?
I have uninstalled every suspicious program and gave up, I didn't update my windows anymore as it was not downloading the files, but some junk. Now, I think that my computer has caught multiple viruses from the updates. Although it runs smooth and I have absolutely no problem running any programs/games, my antivirus keeps detecting suspicious files and just today a random antivirus pop up displayed. I obviously closed it and uninstalled the malicious program.
I use Avast antivirus and I ran multiple scans and I deleted every infected file. The problem is that I delete the files today, but the antivirus will still detect viruses in the same folder a week later or so.
My question is: did I really catch a virus? If so, did I get rid of it by uninstalling and running multiple scans on my computer? And if I did catch a virus, why is my PC's performance not affected? This is the first time I've ever got a random pop up and I immediately trashed it.
