the detections are valid... the htm contains mal iframes at the end of file and the installer contains ad/spy module... i don't know where the infection comes from, but you should run HJT and look for some strange processes, reg entries etc..

I understand Max, thank you for that. Wl use this scaner and feedback. Thanks a lot!

Hi Oldman, here goes the log file of HJT today scan.

Also, when I was trying to repair files by Avast (by clicking Schedule boot-time link), it couldnt do it, - during restart of the system it promptly shows blue window with blinking lines saying smtg like: "error/operation failure/can't repair file". and then, when I'm back, those infectd files still remain unchanged and alarm window anounces virus warning msg when I scan them. My question was: what cud be the true reason of why it cudn't repair infected files? Wud it help more if I had Avast Pro installed? If some files are showing unrepairable but I need them, what to do? Try to "heal" them with other Antiviruses maybe?

Thanks again.

why can't your files be repaired? because the iframe injection is too variable and there's almost no possibility to detect (algorithmically) where the injected code exactly begins, where it ends and the disinfection can be really harmful.. btw: the HJT log looks good..

I was just about to post about your HJT log, but Maxx beat to it.

My question was: what cud be the true reason of why it cudn't repair infected files?

Maxx answered you better than I could have.

Wud it help more if I had Avast Pro installed?

No, the big difference between pro and home is one more provider and a few more scanning confiquration.
 
If some files are showing unrepairable but I need them, what to do? Try to "heal" them with other Antiviruses maybe?

As Maxx said they probably can't be cleaned.

What are the file names, full path and what where they detected as? Why do you need them?

there's a possibility to clean the files manually.. but a condition must be passed: you must be something like (so-called) "IT-pro" ;)

I appreciate you are trying to help, but why do you think this is suspicious ?

If you run a HJT on your own system you will find similar results.
