Problem with Windows XP after updating AGV

[belcantur]

Have been using AVG anti-virus software for over a year, never had a problem till recently when I turned the computer on and it asked if I wanted to download an updated version of AVG... I clicked OK... it then requested that I restart so that the settings could take effect... so, I did. When it came back it didn't load Windows XP properly... It displayed a message stating that it couldn't load the user's settings due to insufficient resources. I could log in but I had no menu options and when I pressed Ctrl-Alt-Del it couldn't access tskmgr.exe - it gave me an error message. I also got messages like: RUNDLL32.EXE - bad image; C:\\Windows\system32\Nvcpl.dll - error loading due to insufficient resources. I thought it got a virus from the AVG download which maybe didn't come from AVG... I wasn't really paying attention at that time but I've since realized that AVG doesn't [usually] ask that you restart so that updates can take effect.

I took it to a computer repair shop where they "fixed it"... only to bring it home to find that nothing had changed. When I called to tell them this, they said they had removed and reloaded AVG, scanned and repaired the registry, and removed spy ware. Everything was working fine. A friend of mine then took it to their house where AVG was removed and reloaded and gave it back to me saying that it was fine. I brought it home and the first time I started up everything looked normal. But, the next time I started up, it had gone back to it's problems!??!! I then discovered that it was hit-and-miss - sometimes it started up normally, sometimes it didn't. One night, I spent about 20 minutes rebooting it before Windows loaded properly and everything worked normally.

I finally removed AGV and downloaded AVAST and it's been working well for two days.

Does anyone out there have any idea whether this problem is specific to AGV's latest version or whether there is something wrong with the computer? If this is something that may happen again, I want to fix it. So far, AVAST seems fine but I had used AGV for some time and I had never had a problem.

Thanks all.

I have not seen or heard of this issue with AVG...a quick at their Forums did not yield any results either.
The Windows error supposedly relates to Roxio from what i found/
I'll do some more digging but in the meantime post back with some more info and specs on your setup...

[belcantur]

Thanks very much. Specs are: CPU-AMD Athlon XP2600+, Samsung 80GB hard drive, 512 MB 333 MHZ RAM, Asus A7V8X Mainboard, Windows XP Home Edition, GeForce FX5200 Video Card. Computer is 3 yrs. old.

Last year, I was messing around and erroneously deleted some set up files... the shop where I purchased the computer repaired it by wiping the hard drive clean and re-installing all the programs... that was about 7 months ago.

I don't run/use anything unusual on the computer. I also have: Ad-Aware 2007, Firefox, IncrediMail, Nero OEM, Spybot 1.4. I have never downloaded Roxio. Since the removal of AVG, it's still working as normal. I would still like to get to the bottom of what caused, or could once again cause, the problem. I appreciate your feedback and help and that of anyone who takes this on.

Thanks all.

I've been using AVG for years and I've never heard of this. They never ask if you want to update to a newer version. The fact that you were asked to re-start tells me that you've downloaded a bogus program with bugs.

[belcantur]

Yeah, SuperDave, I would certainly agree that it must of been a bogus program with bugs but why can't I use AVG anymore. My virus checker comes up clean. AVG has thrice been removed and re-installed and appears to cause the problem when installed. I've been using Avast for three days without problems.

[SuperDave]

AVG will only check for virus. Have you tried checking for other spyware or malware?

[patio]

Dave it may have corrupted some system files...
Go to Start/Run and type in sfc /scannow and hit Enter...
Have your XP CD handy as it will ask for it.

Did you try AVG's Anti- Spyware ?


Here-->AVG-Anti-Spyware-7.5.1.43

[belcantur]

I appreciate all the feedback. Thanks. I tried Start/Run and typed in sfc /scannow and hit Enter... but, the only Windows XP CD I have is a Recovery CD for Windows XP Home Edition. ...It didn't accept that... it said that's not the correct CD.

I keep the computer clean by running Spybot and Ad-Aware a few times a week. I haven't tried AVG's Anti-Spyware. I don't think it's a spyware or malware problem... I still don't know why the problem has disappeared since I started using Avast anti-virus. It appears that an AVG anti-virus download causes the problem.

I've submitted a message to the folks at Grisoft...i'll let you know when i recieve a reply.
Meanwhile Avast is also a very good protection program so hopefully you should be fine.
The program street recommended above is a different type of scanner...it used to be known as Ewido and AVG liked it so much they bought it.
It specialises in trojans and keyloggers which most AV programs misss so it would be worth adding to your arsenal.
Take Care and Welcome to CH !

Thanks so much. Computer still working well with Avast. I'll check back for your msg re. Grisoft's take on the AVG prob.

Also, I've downloaded AVG-Anti-Spyware-7.5.1.43. It's great. Thanks for the tip.

Thank to everyone for the replies.
