Windows 7: Windows 7 clean reinstall but virus(?) remains-- help

Windows 7 clean reinstall but virus(?) remains-- help

Did a clean reinstall of Windows 7 to remove a virus(?)
couldn't detect any virus with lots of anti-virus apps.
'Virus' - behavior: automatically ran strings of dashes (-------------) endlessly in search boxes; opened successive copies of emails as quickly as I could close them in email program; prevented system restore operating; prevented upgrade install, etc.
After a clean reinstall using win 7 cd there it is again the string of dashes in the search boxes!!!
Now I am frustrated --WHAT TO DO NEXT IS MY PROBLEM.
Can anyone suggest a possible course of action here please - please---
Thanks

Did you do a clean install with format? If no, that is what should be done.

Hi Banksia,

In addition to Rich's question, can you tell us what is the source of your Windows 7 installation? A boxed retail DVD? Downloaded ISO?

Regards,
Golden

Which specific AV apps did you use? If you haven't already I would run Kaspersky TDSSkiller (free), Norton Power Eraser (free) and Hitman Pro (free for one use) to see if they pickup anything.

So the only problem you have at present is the -------- in search box ?


What is your browser ?

Check the tutorials above on procedures for doing a clean install. Sorry, I can't find link. You may have made an error in formatting.


You may also consider overwriting the HD using diskpart

thanks everyone for these very helpful comments and suggestions. I am trying them out.

could it be a BIOS problem?
it is not only the search box issue of endless dashes BUT much more importantly it appears to be much more because as I said earlier: I cannot use system restore, opens emails endlessly, and programs freeze, mouse cursor jumps all over the place, etc.
I use Firefox.

maybe if I use DISKPART to cleanall the SSD disk then try reinstalling windows 7 on it. ??

Hum you have a point there too re the BIOS is the mobo going home? I recently recently had multiple problems with one and even the replacement was well zip too - have a squizzy round for burns or bulging caps or something that is obviously way too hot or just lose joints. I also fixed a use machine this week that wouldn't boot and all I did was pull all the connections off and RAM out / back test the PSU volts and away it went no a flicker and it just was not booting at all. I guess we all tend to think of software probs first before the hardware like checking the oil in the car cos it's not running properly and in reality you have two flat tyres !!
