AVG says clear but have I got a trojan

Hi all

I'm running AVG Free 8.0 and my weekly virus scan told me I had about 57 infected objects which it offered to clear. Once cleared I ran another virus check which was clear at the end.

However I keep getting warning messages about trojans popping up (see attachments). I ran Malware Bytes Anti Malware which reported and cleared tons of offenders but the warnings still pop up.

Whatever's going on is really slowing my PC down now and beginning to drive me mad. Can anyone help?

I have also attached the Anti Malware log and a Hijack This log.

Thanks for your time.

Hello please follow my directions in the order they appear;

Download and Run ComboFix
If you already have Combofix, please delete this copy and download it again as it's being updated regularly.
Note: Do not mouseclick combofix's window whilst it's running. That may cause it to stall

Combofix should never take more that 20 minutes including the reboot if malware is detected.
If it does, open Task Manager then Processes tab (press ctrl, alt and del at the same time) and end any processes of findstr, find, sed or swreg, then combofix should continue.
If that happened we want to know, and also what process you had to end.

In your next reply i will need:
  • The ComboFix log
  • A fresh Malwarebytes' log
  • A fresh HiJackThis log
  • An update on how your computer is running
 
Hi Respital

OK, I've run all those diagnostic / cleaner applications that you suggested. I've left the PC alone to see if any of the alerts came up, and whilst it seems to be less infected than it was last night (I think the ComboFix removed a lot of stuff) an alert has just popped up, so it's not completely clean just yet.

The computer speed is not quite as sluggish as it was last night, but it's not back to normal. I've inlcuded the logs you requested and would like to know what you think.

Thanks
