Two days ago while surfing on the internet, my pc started to warn me about a tread and about my disabled firewall. Then, all the programs stopped and windows xp shut down itself. I started it again and I immediately activated AVG Free 8.0 to check if there was a thread. It found Trojan horse, win32/cryptor and then moved them. However my system was not stable, I had to open it in safe mode. I came across error messages about Google Installer and IExplorer.
I tried to update AVG but I can not. I can not even enter to any of the sites like avg.com, etc. Online virus check is also not possible. I can not open the web-sites like Bit Defender. I copied Malwarebytes' Anti-Malware software renaming it to my pc and tried to run it, it is not installed appropriately.
I also tried sfc/scannow. During this process, I had to insert the installation disks, and system had problem with the 3rd one which included spac 3.
I do not know if I removed the virus or not. If not, could you please help me to remove it? If I removed it, I want to get rid of from its effects. Do you think it is safe to use my pc while connected to internet?
I am attaching one file which is the log of the last scan of AVG 8.0.
Thank you very much,
Sefika
