    PC help needed!!

    My computer keeps freezing/ crashing every few minutes probably because of a virus/ trojan horse etc. I currently have AVG scanning my computer but the scan rarely completes as the computer freezes beforehand. I was wondering if there are any better, free programs to download to get rid of all viruses and save me having to reboot my computer every few minutes.

    There is also an AVsystemcare program that pops up every time I start up which I think is also a virus??

    Any help appreciated.

    Don't discount the possibility of a hardware failure.

    You can check your memory to see, google for Memtest86 - it's an image that you burn to a CD, pop it into your PC and reboot. Let it run, overnight is best and see what's reported.

    Prime95 is also another good stability checker, can be run from within MS-Windows too.

    Is there anthing being reported within Event viewer on your PC ?

    (other things you could try are a clean with CCleaner -a google will point you in the direction. Or try Hijackthis, but if you do - post the log here before deleting anything).

    Reset your Pc..before the windows boot screen comes up press F8 on your keyboard..you will be presented with a list of options.

    Select 'Safe mode with networking' option, wait till XP loads up and then do a full scan. This option will load a standard boot of XP without any tasks running in the background, make sure you update your AVG with latest virus definitions before the scan..hence choosing the networking option on the boot screen.

    Saying that if you still have problems download Spybot Search & Destroy from [url]www.filehippo.com[/url], install it then update it with latest spyware definitions etc and do a full scan. Hopefully either AVG or Spybot will remove any nasty viruses.

    Last option is to do a full format of the hard drive, hard to say if it is a hardware problem until you do a scan etc.....hope this helps you out

    thanks might try Memtest86 tonight then if my computer will stay on for long enough. What do you mean by event viewer?

    Just like to add that an avg (7.5 - still downloading popup just came up on screen saying that it had detected 2 trojan horses - one of the had AVsystemcare after it, can't remember the other one was. Do you still think it could be something to do with the memory?
    ------------------------------
    Here's another threat detected.

    While opening file: C:\System Volume Information\_restore(630.......lots of letters + numbers....exe

    Trojan horse NaviPromo.R
    -----------------------------
    My computers ******ed isn't it.

    Also forgot to say..when you boot into safe mode and your PC doesn't crash then you can almost certainly guarantee it will be a virus / trojan etc..but if the PC does crash in safe mode then it will probably be a hardware problem.

    similar thing is happening with me - started about 6months ago - busy doing something and then it freezes/locks up and only option is full reboot. I have tried all the scans etc to no avail. have come to the assumption that probably my graphics card is on its way out. One thing that does use up a lot of my memory is MsMpEng.exe which keeps reappearing even if i delete it through windows task manager. Have bought another pc but still working with this one in the hope that i can rectify it:thinking:

    What do you mean by event viewer?



    Go to start, run and type Eventvwr

    Have a look under the system tab over to the left, in fact check out all the sections you've got. Anything in red is of interest.

    Not at all, even if it is hardware, then it can be replaced. With the above info - it sounds like you've certainly got one or two things to clean up on there though. Ok what I'd do :

    * Turn off system restore
    * Safe mode (as suggested above) and a full scan with AVG
    * Use CCleaner to clean up anything hiding in temp folder locations.

    And lastly try the Hijackthis suggestion.

    One thing you could consider is joining up with the forums over at :

    tek-tips.com/

    If you do, (free to join BTW) - have a search for a subforum concerned with Virus/Spyware and pop a post on, A lot of helpful peeps on there

    There are a few errors in system tab. Sources:- DCOM, Service control manage, and a few on disk. Can't really remember the others as my computer has again frozen :x and i'll have to start downloading avg 8 again. can this be downloaded in safe mode with network connections as someone previously stated.

    btw I will give good rep to all those who have helped(sometime soon), as I don't really have a clue.

    try system restore back to when it was ok, could save you a lot of hassle if it works

    Yes. (if network connection is provided by an ethernet card for example)

    You should try to read the detailed information on the disk errors and report back.

    its been like this for ages. I have done system restores in the past but still seems to crash. - Just thinking now it might be a hardware problem- stupid tiny. lol

    Just out of interest, when your PC locks up and you reboot - what temps are reported in the BIOS (it's normally del/F2 etc on startup) ?

    Check memory and then the hard drive
