Remote Desktop issues.

I was able to use RDP (remote desktop) before I got hit with a virus. Now when I try to RDP into my work PC I get “the client could not connect to the remote computer.” This worked a few days ago and we got hit with a virus company wide. If i disable the firewall in the registry I can RDP, but I do not want to leave the firewall off. Ive been searching for hourse and I cannot find anything that will help me. Other people I work with are having the same issue. It seems as if the virus added enablefirewall=1 in the registry, deleting that entry does not fix the issue. HELP!

TIA
