The programs that won't run are:
The maintenance utilities I use are:
Zone Alarm, Avast Antivirus, Spybot Search & Destroy, Spyware Blaster, Ad-Aware 2007 ,
CCleaner, Xpepius, RegSeeker, HiJack This, Scrip Trap
I have run these programs together, on a daily basis, for several years with no conflicts. The whole system is slower to load, as are individual programs. I went to Trend Micro for a full scan about a week ago, but nothing major showed up. I cannot do an antivirus scan because I can't get Avast to run all the way through. I did do a boot scan before going to Trend Micro.
A scan with RegistryFix (free) showed problems with deskpan.dll in the AcvtiveX area. Is there anything I can do before I wipe the hard drive and start from scratch?
