I notice aston.exe is a shell replacement for explorer, so this is normal to have this entry. However svchost.exe
may be a trojan. Can you check your computer for ALL
copies of this filename. If one exists in the Windows folder (C:\Windows) please let me know - There should be a real svchost.exe, the real file exists in Windows\System32 - this is normal. If you find the file elsewhere also just paste the path names. I looked around on the net and got some information from the support centre at the Aston Shell website, and it seems that the F2 entry in your log is normal, but we had better make sure. One other thing that I noticed from Hijackthis logs using the Ashton Shell was this entry:
F0 - system.ini: Shell=C:\PROGRA~1\Aston\aston.exe ,svchost.exe
That seemed to be in every log with the Ashton Shell? Does that mean anything to you? I'm sure the F2 entry is fine, but like I said it is better to be safe than sorry. On the other hand your Hijackthis log is completely clean, with no visible malware. I want to do one more scan before I give you the all clear for malware troubles, and we can address what may causing your problems. Download http://www.bleepingcomputer.com/files/winpfind.php
Extract WinPFind.zip to your c:\ folder.
Reboot your computer into Safe Mode
Then open c:\WinPFind and double-click on WinPFind.exe. When the program is open, click on the Start Scan
button to scart scanning your computer. Be patient as this scan may take a while. When it is done, it will show a log and tell you the scan is completed. Reboot your computer back to normal mode and and post the contents of c:\WinPFind\WinPFind.txt as a reply to this topic.
So please post back with the Pfind log and also, please can you expand on the problems you are having - I need as much detail as possible for me to determine what the cause is.
