Hello everyone, I am new to ever having any problems with my spf until yesterday. I keep getting smc.exe has generated errors and will be shut down. I have tried to uninstall and reinstall. Ran ad-aware, disc defrag, ccleaner, avg. ( did have trojan horse downloader.generic7.z) I thought it was healed. (gone) I can not even get it to open through programs (manually) once in a great while it will open but then it freezes. I am thinking maybe this is because expiration on freeware or trial. I have been using for at least 2-3 years maybe more. If so can anyone suggest a free firewall that is similiar and would be compatible with my system. (windows 2k,cc cleaner, avg virus, frostwire, reg cleaner, and internet explorer 6.0 searchbar. I have a Sprint wireless card. I do not know if this is related I am iunable to retrieve my automatic updates from windows microsoft and I have been able for years and now I cannot get them. P. S Thanks for the help, i will be researching the highjack disc logs, i will be up all night, learning how to use highjack disc, reading and searching.
