Ran this, except everytime I run it, Windows Explorer encounters an error and needs to close.
I can never complete an entire scan.

I have used this many times before, it is very good. Always make sure you run in safemode. Boot into safemode by pressing f8 or sometimes f11 on startup this gives you boot options for windows.

webmaster – I have both files lpt$vpn.467 and defs.ref downloaded into my doc file.
Neither will run – both get windows saying they can not open because they can not identify who created the program?
I used Internet Explorer as the creator and got “memory could not be read” on both.
Can you help.

Tim you need all the zipped files, and they need to be put into the same folder… then run the sysclean application.
By the way… I would do this in safe mode… works alot better!
