hi, i have been experiencing a strange problem.I got a new antivirus , NOD and it cleaned lot of viruses last week, two days later i found that i cannot see my hidden files even if i am going to tools>folderoptions> show hidden files. i click this radio button and i go back and see it is not clicked. no hidden files become visible. i followed a previous thread and performed the hjt scan following the directions given to run the hijackthis.exe. i am attaching my log file. Please let me know as to what i could do. THANK YOU.
