thanks for the suggestions, however I cannot open any application. I get a warning:
"Application cannot be executed.The file is infected. please activate your antivirus softeware."
This is not come from avast. What I did get from avast was:
avast! has detected a virus in the operating memory. Suggests a scan in the boot phase. I have done that a couple of times and I have 7 or 8 file in the chest.
I normally use my computer on a protected network at work. I was on vacation and used a home network and failed to realize I had no protection.
Just how screwed am I?
