Virus I think? Please help

Hello,

I think I have a virus on my computer, running Windows XP, Mcafee. Started to get problems booting thought it was windows playing up and tried to repair. I keep getting init.exe has encountered a problem and needs to close coming up all the time. Noticed that when connected to the internet even when I wasn't on internet explorer the router was going mad. I loaded malwarebytes copied from someones laptop I borrowed in safe mode & it cleared lots of trojans etc. I then rebooted and tried it againand found another 3. i was told to update Malwarebytes and turn off router when done, but it wouldn't update got an error. I uninstalled & reloaded Mcafee as the program was coming up without the pictures for the icons. Ran a scan and it got stuck on a certain file, but it found 380 errors and quarrantined 340. Had to cancel scan. Ran out of time and shutdown, next time I tried to boot up I didn't get any icons or task bar, have managed to fix that with some advice from this site, thanks. Now I have desktop up with icons, I have the following errors : run-time erroe 10013, the requested address is a broadcast address, but flag is not set & error loading C:\windows\xccdf16_09013a.dll, I've still got the init.exe report to Microsoft box as well. Can someone help and let me know the next move, I've obviously got a virus, but don't want to run Mcafee again if thats been corrupted as well, I've been working on this for a week and it's driving me insane and don't want to connect to the internet if data's being uploaded someone else. Thanks.
