...Code 1073741818. From Googling the above, everyone says it's a virus or worm. Norton Antivirus doesn't find anything. Whenever I connect to the internet, the above mss. appears. Also, the computer is alternating between running really SLOW and then running normal. But the normal times are shorter than the slow. There is one running process that doesn't go away, called Picture Package, which I just uninstalled. Anyone got any ideas of what I should do? Especially considering I can't connect to the internet with the computer in question. Thanks in advance!

What are you doing when you receive the error? Does the machine blue screen or reboot? Are you running an up-to-date anti-virus program? Life's more painless for the brainless.

Upon bootup the machine is slow and makes repetitive motor noises like it's working on something. Then, it alternates between briefly running normal and then slowing way down (like I click on an icon and wait for 5 minutes for it to open). Then, if I try to connect to the internet I get the folowing: "NT Authority System The system process C:\WINDOWS\System32\lsass.exe terminated unexpectantly with status code 1073741818. The system will now shutdown and restart." This is a friend's computer and she says she always clicked 'yes' when her Norton Antivirus popped up and asked her to update. I've run: Registry Booster2 CCleaner AVG Anti-Spyware Spy Sweeper IOBit Defrag None of those are finding anything. The one thing I can't do is run an online scan, which I'd like to, but I get the error message whenever I try to log on, then it shuts down. Any suggestions??

Sounds like the Sasser virus. Take a look here for a temp fix and to obtain the removal tool: http://www.symantec.com/security_re... Life's more painless for the brainless.

Thank you for the advice, I did go to the link above, followed instructions, and after the removal tool ran I got a message saying "no instances of the Sasser virus could be found." During this process, since I can now go online (using the instructions from symantec, which is a temporary fix making the shutdown wait for 2.5 hrs instead of 60 sec's), I noticed something interesting. Norton Antivirus had a bunch of red "X's through it saying nothing was updated. I'm wondering if my friend was clicking "OK" to a frequent SCAN of her system, but not an actual UPDATE. She not very computer literate, so she doesn't know the answer to this. One other thing, her husband downloaded some UPS WorlShip 9.0 thing. I don't know if this matters. I tried running it just to see what it did and I got the message "Server Busy." What? Anyway, any more ideas on what I should do?
