Hi
Just a few days ago, I scan my laptop with Kapersky Antivirus and it has detected Trojan threat from some downloaded files. What I did was I clicked something like "quarantine files" and tried to delete the threat. And it says it unable to quarantine/recover the files nor delete/clean the virus. Eventually, I ignore the problem as when I rescan my computer again, it went no threats detected.

On the next following day, I was unable to browse websites on Google Chrome neither Mozilla Fox. Only able to browse on Internet Explorer. I did uncheck the LAN settings, still unable to browse. Rescan my PC still unable to detect the threat. I also deleted the files that contain Trojan threats as I remembered the files. What comes to worst now is, I uninstalled Google chrome and tried to reinstall chrome.. However, when I tried to download chrome file from the website, I'm unable to download chrome as it doesn't appear anything as I click "download chrome"

I suspect my laptop has infected with malicious virus. How can I fix my problem so I can browse internet with ease (through Google chrome and Mozilla)? If happens to do system recovery option, will I have to back up some important documents/files before doing so?
I'm using Windows 10, Lenovo G405s

I used a product a few years back that broke my browsers. I did a bit of Googling back then and came up with 2 commands that ended up fixing the issue.

Try using these in a CMD prompt with Admin privileges (easiest way: search from start menu, right click on CMD search result and run as admin.)

ipconfig /flushdns
netsh winsock reset

Not going to say it will work, but it just may.

This happened about 6yrs ago yesterday, and thanks to Facebook for reminding me yesterday.

If you don't want to deal with having to scan and remove the virus, just remove your product key from windows and reinstall it and then put the product key back. If not, you should do a full custom scan of everything with Malwarebytes and adwcleaner too.
