chrome_url_fetcher


Recommended Posts

When opening my temp folder, I found more than 320 folders with the name "chrome_url_fetcher" followed by some numbers that I believe are ID's, could anyone explain to me what this is? I use the Brave browser, I'm afraid of some information having or being leaked at some point. Some files within some folders contain things like "extension_1_0_1694.crx" where the numbers vary, and others are a bunch of letters that seem to be of some extension, but searching on Google doesn't turn up anything, followed by something that looks like a version, and then more letters are random numbers. Could anyone explain to me what this is, if my data is at risk?

In my browser I use some extensions, but not all of them are enabled. These are "BetterTTV", "Google Translate", "Malwarebytes Browser Guard", "MetaMask"(Disabled), "SteamDB", "uBlock Origin", "Return YouTube Dislike" and "Volume Master"(Disabled - I use this extension because Most of the time, some films and series are extremely low, so it allows me to increase up to 600%)
I've already done a full check on the PC, using Malwarebytes, and it didn't find anything.

Pick just one of these 4 providers. And be aware that you need to modify 1 time for IPv4 & a 2nd pass for IPv6

  • Google Public DNSIPv4   8.8.8.8 and 8.8.4.4   IPv6   2001:4860:4860::8888 and 2001:4860:4860::8844

Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program:   FRSTEnglish.exe
