Mail & Safari crash repeatedly even after erase 10.6.7

Question

I came back to the Mac to get away from Windows issues but still need to run Windows. So running Windows 7 64 bit in bootcamp & using that as a Virtual Machine in Parallels 5. Bought the macBookPro 13 in April 2010. Was running fine until Feb 19, 2011. On that day, Pages crashed, going from Pages to desktop to blue screen. Over a week it & Safari got worse with repeated crashes so that it got so I wasn't even able to boot.
AppleCare & Genius bar have tried various solutions leading up to & including 2 erases--the 2nd time not even restoring much at all.
Did not even have mail set up until after the erases. All I have on the Mac side since the erases is iLife & iWork & then later reinstalled Parallels. But the crashes happened before installing Parallels. Safari & Pages crashed before erases. Since it has been Safari, mail & finder & possibly Pages & Numbers-can't remember.
Even after the erase these have continued intermittently. Have been working in Bootcamp lately since I have Outlook there & did taxes in Turbotax Windows. It has been pretty stable.
The mac has also had trouble booting & had finder crashes so it seems to be mostly the various mac apps, but not just 1 of them. Right now Safari seems to be working ok & hopefully will let me post this. But other times it crashes & then it may work fine for several hours.
Anything known that happened around Feb 19 that could lead to this?
When did 10.6.7 come out?  There were some reports on the Parallels forums of possible conflicts between that & Parallels, although I think that was parallels 6 & I'm running Parallels 5.
Most of the crash reports seem to say BAD_ACCESS_SIGEV (or something like that)
& the thread is 0. This seems to be true whether Safari or Mail. Can't remember if Pages or Numbers have crashed but I haven't used them much.
I'm told Macs don't get viruses or malware, but then someone said maybe they do.
So far no reason has been found for this but the next step Genius bar is going to do is replace logic board, memory & HD. But hardware tests hadn't shown anything.
So just wondering if there might be any other possible explanations that maybe should be explored. Genius bar is taking good care of me, but this is really disrupting use of Mac & really blindsided me since my memories of Macs (& what my brother confirmed has been true with their macs) is they just work.
So before I take it in for what is hoped will fix it, but really apparently that is not known, wondering if there might be something else to look at.
Also wondering if anything on Windows side could affect the mac? I have proprietary co software in bootcamp as well as Outlook 2007 that I sync to winmob phone for biz.
But the crashes started up again after the erase before installing parallels. Bootcamp has mostly been stable although I did have 2 windows blue screens shortly after the erase.
Again, any help or suggestions would be appreciated to help get this back to what I expect from a Mac. Its also embarrassing in an office of Windows users to be having all these problems on my Mac.

There's a bit of Toshiba software that's likely not compatible with Mountain Lion:
1   com.toshiba.pde.e-studioeFiling          0x000000010fe010eb -[TTSNMP_eFiling initWithHost:andReturnError:] + 278
2   com.toshiba.pde.e-studioeFiling          0x000000010fe02860 -[TTPDEEFiling_eFiling initWithManager:] + 562
3   com.toshiba.pde.e-studioeFiling          0x000000010fdfe336 +[TTPDE_eFiling pdeWithManager:] + 44
4   com.toshiba.pde.e-studioeFiling          0x000000010fdfcfdc -[TTPDEFactory_eFiling PDEPanelsForType:withHostInfo:] + 373
I'm afraid there's no answer here other than asking Toshiba when they're going to update their software.
