Hi. I am trying to get rid of this nasty program called SpyDefender. It is claiming that there are worms and other things on my friends computer and I know it is not true. The anti-virus he is using is AVG Pro, that does not come with bugs. I am surprised though that it did not provent this program from downloading. This program SpyDefender has hijacked my friends computer. How can I remove it without it doing damage to the computer? I was going to try SpyHunter, but when I tried to install it, the computer said that it was missing the "ExecutionGuard.dll". I Would be so gratful for any help.
