I have had Spywareblaster installed for some time and updated it regularly. However, seeing there was a new update shown on the PC Advisor site, I double clicked on the icon to download it and immediately got a "This program has performed an illegal operation and will be trminated" message Details: SPYWAREBLASTER caused an invalid page fault in module SPYWAREBLASTER.EXE at 0197:0040bbbd.

Next I removed the program using the uninstall tool provided and donwloaded again from MajorGeeks. Reinstalled and got exactly the same result when trying to run it.
