Windows security Centre..shield symbol....

My security "shield" symbol has a red circle with an X in the middle; I have
tried to update everything, which shows it's up to date, but it remains the
same. I had the AVG free anti-virus on there and it kept saying parts of it
were out of date, although I updated these and they were successfully
updated, it too had the red ball with a + or something in it...no matter how
many times it was supposedly updated. I ended up removing it and
re-installing it and the results are still the same. I cannot get the
security shield back to it's normal symbol either. I currently have nothing
on there except firewall as I think if I download it again, it will still be
the same.

You're infected. I don't know name of threat (could be karna.dat or
brastk.exe), but I just cleaned this pc of those (along with multiple other
trojans, viruses, etc.). AVG has "done a Norton" they used to do 1 thing very
well, now they do everything poorly. Try downloading Spybot S&D,
SuperAntiSpyware, or Malware Bytes AntiMalware. And then start pc in safe
mode with networking, then scan, scan and scan again. You can get all these
for free at download.com (Note: With these viruses I had problems installing
some of the programs.)
These are the sites I checked out to help me fix this pc:
forums.mcafeehelp.com
community.norton.com
bleepingcomputer.com
geekstogo.com
I mostly used them to figure out what I had.

If you're gonna do google searches to help you, make sure you have McAfee
SiteAdvisor. A lot of links that displayed from the searches I did were not
recommended.

NOT literally that youre infected it means your Security Software didn’t
qualify to the standard set by Windows Security Centre to protect your
machine and also there are known issue that Windows Security Center has some
concern identifying 3rd Party protection tool's status if its updated or
not.

Have you ever experienced a "yellow shield w/exclamation point". Whenever
that is showing in the bottom right corner of my desktop, my IE program is
unresponsive.

Run a /thorough/ check for hijackware, including posting your hijackthis log
to an appropriate forum.

When all else fails, HijackThis v2.0.2
(http://aumha.org/downloads/hijackthis.exe) is the preferred tool to use (in
conjunction with some other utilities). HijackThis will NOT fix anything on
its own, but it will help you to both identify and remove any
hijackware/spyware with assistance from an expert. **Post your log to
http://spywarehammer.com/simplemachi...php?board=10.0,
http://forums.spybot.info/forumdisplay.php?f=22,
http://aumha.net/viewforum.php?f=30, or another appropriate forum for review
by an expert in such matters, not here.**

If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA or Geek Squad) computer repair shop.

I was having the same problem and checked my clock/calendar thanks to an
earlier post about website certificate problems. My calendar was on wrong
month/year--once I fixed that, my AVG was fixed as well.

I had the same problem. I found that I had inadvertently changed the calendar month on my date/time. Resetting the calender to the right time cured the problem immediately.
