I got my start in electronics and have a background in
that too. I took college courses in electronics and am no
stranger to repairing circuit boards. I'm no stranger to
soldering irons. Well that's what we called them. I used to
repair TVs, radios and such years ago.

When I need to repair a blown component like a bad sound
card, video card or controller card, I replace it. I haven't
needed to repair an actual circuit board for at least 15 years.
The last component level repairs I did for a computer was
replacing burned out components on my old Amiga computer's
motherboard. But I gave up on all that stuff, just not worth the
hassle any more especially with these newer multilayer boards
with tiny components and surface mounted chips. It can be done
but it's usually not worth it.

MCSE is pretty useless in my current repair field.
However it's good to learn if you take a proper course such as a
computer science course at a college. I took a three-month MSCE
course and found I had already learned most of the stuff on my own.

I used Bitdefender's bootable CD to remove malware from the
restore point files and it did not solve the problem. I rebooted
and the malware was written there again. Only when I turned off
system restore and when I rebooted, I got a popup stating that
it couldn't find a file in the system restore folders that were
deleted. Then I did a final scan and the malware was gone,
system fixed.

I know how system restore works and I'm 100% sure it can
be exploited by malware writers.

No. I just clean them I don't study them. I do this sort
of thing a lot and don't really keep track of each piece of
malware I remove. I remove scores and hundreds of trojans and
worms from systems. I probably still have the scan log though if
I find it I'll post it here. This was more than a year ago when
I removed it.
