I wonder if anyone can help with this problem. A short history:
In July I acquired the TDSS trojan from some site link. I removed it using MBAM, Windows Malicious Software Removal and Zonealarm Extreme Security.
My system is now clean as far as I know.
I then enabled automatic updates from Microsoft and downloaded and installed everything including SP3.
Thereafter when I start up Windows, my icon fonts look fine - default setting for Windows Standard, but the task bar fonts are sometimes too large. When this happens, if I then click on a programme icon those fonts also grow very large - to probably 14 points, then the rest of the desktop, menus, titles, etc. all follow suit.
If I restart Windows this problem usually goes away until the next or second-next time that I start up - ocassionally, like today, it doesn't.
I have followed advice to change font settings and sizes, even the font type, then after restarting have reset to the default and everything is OK for a few starts, then the problem recurs.
I've searched the web for advice but can't find any relevant to my search terms, other than strong advice to remove SP3, which I did, then installed all the security updates - except a few which will not install (inf files missing).
I had other reasons to uninstall SP3, relating to monitor colour not being reliable and associated problems.
I have no real desire to reinstall everything as that is a real pain and would appreciate any advice if available.
Also system restore has not worked since the infection.
I have noticed that this is related to the yellow Windows Update icon appearing in my toolbar - before it appears the fonts behave normally, as soon as it appears the fonts grow very large.
I should perhaps also state that I have the font size set at 120% in the advanced section of Display Properties - something which has never been a problem before.
I have XP SP2
ZoneAlarm Extreme Security
Mostly graphical software - Adobe
