various errors when downloading programs

For some time now I have had problems downloading files/programs from the net. Things like OS critical updates; Adobe updates; VMware trial software; games; virus definitions. The download run into problems when unpacking - most common error is that verification failed but there are also failures in unzipping files (NAV installer being the most recent).

I have checked a number of forums and found similar problems but none seem to work (eg. mounting from disk utility). The only thing I haven't done is reinstall from OS archive disk as this could entail reinstalling a lot of things (mind-boggling).

I have a MacBook (2GHz Intel Core 2 Duo with 1 GB 667 MHz DDR2 SDRam) running OSX 10.4.11 and also have Parallels 3 (build 5608) running Vista. The download problems seemed to begin with updating the Parallels software. I received the verification error or a checksum error. I resolved this problem by using different download sites. When investigating this problem it was suggested that the ISP provider was at fault. Is this possible?

I have tried the same solution on other software with which I was having problems but it has not worked. I am (as they say in many forums) at my wits end and would greatly appreciate some help.
 
I'm not a techie - but I thought I'd give this a try. Does your download have the correct number of bytes in it when it is downloaded? (you may not know if it is zipped). And next,
I would suspect my unzipping software since it is happening to everything. YOu might delete it and download a fresh copy.
