I'm going to keep this as short as possible. My PC is acting EXTREMELY weird.
I have not been accessing any kind of weird sites, clicking on links or opening e-mails. Suddenly, today, my PC turned off my Firewall (Windows Firewall) and gave me a blue screen. Upon checking, i now see that i have two processes, Udel.exe and Udell.exe being started up from my Username\AppData folder. There is also an empty folder named Udel in there which i cannot delete. My AVG Free is totally turned off, can't restart it. My windows firewall is said to be off and "managed by the system administrator" and i can't do anything with it. If i go into Task Manager i can see udell.exe as a process and if i try to close it, it prompts me that if i do this my system will shut down. I try closing it, my screen goes grey and black, then blue-screen, then restart, and recover from a serious error.
What is this virus and how can i get rid of it? Websites are loading extremely slow and some of them directly to source code. And weirdest of all, i can't find ANYTHING about these processes online, like the virus never existed. If i try accessing yahoo mail it leads me to http://realityadnetwork.in/.
Please help me as soon as possible.
