Thankyou For the replies given to me so far,I appreciate the help. I've waited reposting until I'd tried all the suggestions and some others. I work with my computer alot but am not proficient at programming or anything along those lines.
I've tried the scan and repair from Trendmicro(found 3 infections which were not cleanable but were supposedly deleted) but Avast detected the virus at startup again-"memory is infected!"
I have performed several boot time scans-and deleted the file but it returns again.
I tried going into the registry using regedit command to try to delete the entry "notepad.exe = popuper.exe". It is not there. As a matter of fact when windows tries to shutdown there is an error message posted for a few seconds"popuper.exe DLL Initialization Failed". This always appears when shutting down now.
My desktop now appears differently-I previously had an astronomy photo for my screen but my desktop is just blue now with all the shortcut icons still present.
I've cleared temporary internet explorer files and offline files but it doesn't help. I currently use Mozilla Firefox as I had in the past. The popup ads still appear,some for a pornographic online dating service. These have the Internet Explorer icon present in the upper left corner when they popup.
I've downloaded the Startup Viewer but do not understand Polonus instructions for making a map,etc I HAVE downloaded Hijack This and put it in a folder on my desktop. I performed a scan and then posted it to
http://hijackthis.de/index.php. I now have a list of the entries I would like to fix by Hijack This. BUT when I check these off in the list from my scan and click "fix" I'm told the entries will be deleted then the screen goes empty. I scan again and all the checked items I wanted to delete are all stll there.
I have also gone thru windows explorer and located the "hp temp file" containing the "Avast located infection" but the virus installs another temp file at reboot. Avast always detects the virus at the beginning of a computer session but is unable to move it to the chest.
I haven't fixed my problem but I now have some entries I'd like to delete so maybe there is still some hope in removing it without wiping everything out.
Thanks, John
