If it is a bad virus that won't let you do anything on the computer, follow the instructions on this link. If you can install programs on your computer, follow only steps 7 and 8 from the above link.

Yes it is possible but it may not fully remove the virus, it depends upon the type of virus infection.
If you have not installed a virus protection program, then this makes your task more difficult.
I would try a WEB base virus removal program first, provided you can connect to the Internet. Try these WEB base virus links first and if successful then install a virus program.

If all fails then you need to format your hard disk and install Windows again together with the computer's device drivers and your programs.

your PC might be infected by virus(es) that's disabling the registry editor. The best thing is back up your important data, re format C drive and re install it.

Do an online scan here http://www.bitdefender.com/scanner/online/free.html

Try downloading Malwarebytes (malwarebytes.org) and run it. If you can't run it on that computer, get a recovery CD (such as the Ultimate Boot CD for Windows) and use that to try and recover.

Your data - In order to ensure don't copy any infected data backup as few executables as possible. BEFORE restoring your data make sure you have antivirus installed and up to date. Perform a full scan after copying the data back to your lt. Put in the recovery disk and restart your computer. Look for a prompt on the screen to "boot from disk" while it is booting. Press the key it says to press and follow the directions from there. If there isn't a prompt to boot from disk try pressing Alt and F10 while it boots.

You can visit this link to purchase recovery discs for your unit. Should do a factory restore for ya...

u may try by disabling all the firewalls on your computer and then u may observe the connection
