Before the chrome problem:
Ok, I got a virus. I was sadly using Windows (I needed IE), and I went to a website which somehow got onto my system. It installed XP antimalware 2010 and basicly wrecked my machine.
So, I reinstalled. Which was surprisingly simple. Only a case of a booting CTRL > F10 and reinstalling. So, I then restored all my programs and files(which I had obvously backed up earlier). Then, I went into Google Chrome and went to one of my client's websites.
Then, the virus returned. Somehow, when it had primarily got onto my PC, it had found the registry file(lying around in my folder) with the username and password, and then redistributed itself. So, I changed all my passwords and blanked the contents of the website(I had a backup which I later restored to it, luckily!).
So, I removed the virus for a second time. I did not reinstall this time, because I didn't deem it necessary. But, that had concequences:
So, I opened chrome after a victorious complete removal of the virus(so it seemed), and a popup came up saying I had a virus. At the same time Windows Defender(My favourite anti-virus) said there was a virus. But, when I killed the pop-up, defender was fine. I even did a full scan and it said it was fine. Ok, then ran msconfig and I found an odd startup application. Sadly I forgot the name. But I looked it up on the internet and it said it was a virus!
So, I found the file, removed it and rebooted. The problem persisted and the file was back!
I removed the file again, and it still persited, so I booted of a puppy linux cd, reached into the hard drive and deleted the file. Hey Presto! It worked.
The real problem:
Now, I opened chrome and it said loading. I was impatient so I opened another tab and hit the 'Home' button. Still, it did not work. It only did an odd thing to the bookmark toolbar. So, I tried firefox, and I accessed the internet.
Now everywhere I looked, the solution was to and --disable-sandbox, which worked. But not very well. For it also set loose bookmark sync which meant that you may randomly be brought to one of your bookmarks when you clicked on a links.
So I read further into 'sandbox' and it looked as if it disabled chrome's own little security 'firewall', which was the last thing I wanted. So, I removed chrome.
Don't worry! That wasn't my solution. In the end I found this forum post, which linked to this executable which removes the problem, and lets you browse with chrome in peace and with the sandbox on!
I hope this helps anyone out there!
