!!VIRUS WARNING!!!
I just had a hell of a time getting rid of a redirect virus.
It's called SendoriUp.exe and it's a redirect virus that appears to disable your anti-virus and prevents you from running malware bytes. It also will lock you out of stopping the process claiming you don't have the administrator authority.
I was able to remove it via add/remove programs and then had a file shredder work it's magic on it.
To check to see if you have it hit ctrl+alt+del and go to the processes tab.
Click name and search the S's for 'SendoriUp.exe'
IF YOU HAVE THIS FILE. DO NOT PANIC.
Go to Add/Remove Programs.
Remove Sendori and reboot. Close out of any web browser that pops up immediately.
Upon rebooting make sure all your anti-virus is up to date and working.
Make sure you empty your recycle bin and I HIGHLY recommend getting a file shredder to make sure any trace of it is DEAD. Advanced System Care 6 has a nice one, I used the 'Gutman Method' which takes a while but it's effective.
I figured I got this from an accidental click while browsing the 'Game Grumps' tag on tumblr that rather than playing a video took me to a site I didn't want to go.
Please be safe and mind your clicks.
