I think this is the same thing I been getting for a long time now...
I get this on my XP SP3 laptop also.... error 42145 Installer archive is corrupted...I have been getting it for some time now and about a year or so ago did a recovery and right after the recovery was done, I installed Avast 5 at that time and still same issue...I googled it and with all suggestions came to the conclusion that it is nothing to worry about.... If I scan with any other scanners as Malwarebytes or Superantispyware or Spybot or ClamWin Portable.. etc. They never find this...Although Avast only finds this on a Boot Scan not on regular scans ....I deleted all my restore points shut off restore for a week cleaned all out...Did all kinds of tests Stil there on "Avast Boot Scan" Only...
In Other words "If it's the same issue as mine?"..... I don't think it's anything to worry about...Cause my laptop has never ran better...
Cheers !!!and safe surfing!!!
