My son has come back from uni with his(my) laptop which has been infected with a trojan horse which he picked up from clicking something on MSN. This caused continous sites to keep coming up when on the internet. He had Norton antivirus on it - trial version, which he didnt update. We have the laptop home now and I am trying to fix it. I have run AVG antivirus on it and found 18 problems which AVG has healed. So now I can connect to the internet, but cant get on any sites - gets half way and is timed out. Any suggestions - I am thinking of wiping it clean and starting again - saving any important documents, but will these be infected? If I pay for a antivirus program like Norton will that fix the problem?
Thanks I have done that and run spyware and am now on the net. I am now getting errors when I star up the laptop says something like ipwins.exe cant run because it needs services.dll. What is this? Also I keep detecting Trojan Horse collected.AF?????????? Any advice greatfully received
