I fixed the Google links redirecting to rle822x.cn.
After fixing a trojan/malware infection, I wound up with Google redirecting my search results to various websites, followed immediately by rle822x.cn. The only way to avoid it was right clicking the link and choosing to open in background or duplicated tabs.
Hijack This! showed no redirects, BHOs, or other suspicious items. Avira, Spyware Blaster, Malware Bytes...all of them showed a clean machine.
I changed my "hosts" file, and I added rle822x.cn to it. This stopped the page from loading, but still left me with a "cannot load site" message and required me to go back and take the long way through. The only information on the web said I had to reformat my system. (Something I avoid like the plague.)
I performed a simple edit in my Configuration file, and can now go directly to any page from both my Google search results and my Google home page links.
Fixing it requires editing values (in mine, only three) in the Firefox configuration. You will keep a copy of the original value. Disclaimer: Don't do this unless you're comfortable changing the values, I'm not responsible for errors, etc, etc...
Type about:config in the address bar.
Type :patterns" in the search bar.
I have the extensions adblock plus and the filter for it installed as extensions, and "patterns" gave me 4 results, 3 with string values (really, really long strings!).
My results were adblock.patterns, extensions.adblockplus.synch.Filterset.G.patterns, and fgupdater.patterns.
Right click the first entry, choose copy. Paste it to a word processing document. (This is your backup.) Go back to the entry, right click, and choose edit. Go to the end (right arrow key), type one space, then type rle822x.cn.
Repeat this action for the other two. (You may have more or less.) Save the document with your original entries as backup.
You should now be able to use Google normally, without being redirected or hijacked by the rle822x whatever-it-is.
