I have been having problems with my Windows Explorer, Recycle Bin and other internal folders upon a fresh reboot. The problem is that they TRY to open and stabilize and just keep on trying. I call this "flashing windows". If I get on the internet prior to any attempts to open these internal folders, the flashing does not occur and all my PC directories are available to me without problems. I have been exploring whatever I could find and all suggestions made to me regarding the cause of this problem, i.e. trojans, viruses, registry corruption, hardware issues. I have my AVG running constantly and keep it updated. It found nothing. I downloaded and ran another virus scanner (Gladiator Scanner) and it found a virus in my modem directory. (I have a dial-up modem connection to the internet.) I don't know what to do with the infected file it found; so, I left it in its "Infected" folder. I have run two on-line trojan scanners: Both found the same ONE port open (5000) and told me which trojans use that port. I downloaded TDS-3, configured it as per instructions in one of these forums; and it found NO trojans. I have noticed recently that Zone Alarm has been getting many, many little lock icons on it; and when I pull the control > alert up, I find many are from the same ports/IP addresses. I am wondering if this has something to do with my PC problem. I went through ZA's "program" tab and removed all except IE, OE, AVG, ZA and my WS_FTP program. Then I went into my Windows > Temp and Windows > Temporary Internet folders and cleaned them out. In the temporary Internet folder is the "IE5" folder containing an "index.dat" file and many numbered/letters folders, many of these being full. (I cleaned them all out, leaving the folders.) Then, I rebooted. When my Windows ME came back on (before I clicked my internet connection), ZA asked me if I wanted Windows Explorer to have server rights to the internet. I found this puzzling because I thought Windows Explorer was my "internal" browser; and I wondered why it would want internet access. I said "no". I then tried to get into one of my PC folders, i.e. recycle bin and, again, the flashing windows began. I stoped them by rebooting. Then I clicked my internet connection to come here to inquire about ZA. (I have already gone back to attempt to get into my PC directories and have been able to without problems--the process described above.) Can anyone in here help me figure out what is occurring? NOTE: This PC was given to us over two years ago. It had these "flashing windows" at that time. My son and I use it and put our personal logons in. The flashing did not show up on our personal logons; so, I thought it had disappeared. From that time to this, I have put in a new modem, a new processor (Pentium III), a new motherboard (AOpen) and more memory. The latter two were done last September (while we still had our personal logons) and the PC was working beautifully until early December when we were trying to get our screen resolution the same for both logons. We were told to delete our personal logons, change the screen resolution and, then, put our personal logons back. This is how we found the "flashing windows"; and when my search for solutions began--as described above. Please forgive the length of this post. I simply wanted to be thorough.
