Went out catfishing last night on the James River and my uncle and I caught 2 around 5 to six pounds and as the storm was coming to us I hooked into one that was 33 inches long and weighed 26 lbs and 4 ozs after we got him in the boat the storm was close so we headed on back to the ramp.
If your system restore has gotten turned off, you probably do have a virus. try going to download.com and download malwarebytes. it's a free, but really good tool. that should find anything that would shut down system restore and maybe find what caused all of your problem.
You might try a system restore to the date you last used the program you want.
If you are using XP go to start , all programs, accessories, system tools, system restore and it will promp you there. hope this will help you.
