Avast5 changes screen resolution

I use Av5…and also installed it on my Mom’s pc which runs XP(running it for a couple months)…it has worked fine for me forever(Vista).My Mom calls me and says her pc is acting up…Avast is frozen and her screen resolution is whacked…with huge icons.So I go there and cannot get Avast to work…it’s acting like it’s corrupted.So I uninstall…and pc is happy as a clam…proper resolution…etc.So install a fresh version Av5…but as soon as the pc restarts it starts at the proper resolution…blacks out and goes back to the whacked resolution…try this a couple more times…same results.And Avast seems to be working perfectly.Any ideas?

Sorry but avast didn’t change your Mom’s screen resolution, it has no function/settings that is able to do that and has no requirement to do that either, so I really don’t know what is going on in your Mom’s system.

Like you I have never had a problem with avast, certainly not screen resolution and I have had it installed no a few systems with many different monitors and resolutions for over six years.

Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?

Some information about the system:
Monitor TFT or CRT and resolution; CPU; RAM, Graphics card, etc. ?

Hi David…thanks for answering.Yes…I agree wholeheartedly with you…Avast should have nothing to do with screen resolution. But what gets me is when I remove it completely her pc works normally and keeps her original resolution which is 1024 x 768.But once Avast is installed the pc boots up in that mode then black screens and goes to 800 x 600.It’s a rebuilt pc with XP which came with AVG up to about 2 or 3 months ago and then I installed Avast…it has worked fine up until a couple days ago when she mentioned her screen all of a sudden went wonky after she booted up…I am sorry but I do not have any of the specs of the pc but when I get back into town again this week I will get them.I think it must be something else but I just wanted to see if anybody has ever experienced this.One thing I remember tho is when I looked at it today Avast gave a msg and I am sorry but I can’t exactly remember the wording but but it was to the effect that it was corrupted/not working properly…and gave a fix/repair window …which went nowhere…I couldn’t update or use the program so I uninstalled it.After I reinstalled it, it returned to normal…working properly…except for the resolution thing…(I did this a couple times just to troubleshoot and confirm the relation between Avast and resolution)So right now we just change the resolution and it stays until she restarts her pc.Thanks again and I will be back with the numbers in a couple days…:slight_smile:

Whilst I don’t know if any sort of conflict (with a previous AV or remnants) might cause this type of effect, it is worth ensuring AVG is completely removed.

  • Ensure that all remnants of AVG are gone - AVG8.x (or higher) Remover, download tool from here, http://www.avg.com/download-tools there is a 32bit and 64 bit windows version, ensure you use the correct one.

The corruption error from avast is certainly a possible indication of a conflict, so perhaps the above removal tool might help, followed by a clean reinstall of avast.

  • Download the latest version of avast, 5.0.594 http://files.avast.com/iavs5x/setup_av_free.exe and save it to your HDD, somewhere you can find it again (if you didn’t save your last download). Use that when you reinstall.

  • Download the avast! Uninstall Utility, aswClear5.exe find it here and save it to your HDD (it has uninstall tools for both 4.8 and 5.0).

    1. Now uninstall (using add remove programs, if you can’t do that start from the next step), reboot.- 2. run the avast! Uninstall Utility from safe mode, first for 4.8 if previously installed and then for 5.0, once complete reboot into normal mode.- 3. install the latest version, reboot.

No problem, glad I could help.

Thanks,David!..I’ll give that a try when I am at her pc again…:slight_smile:

You’re welcome good luck.

Also check and see if the C++ 2008 redistributable is installed on her machine. Avast! needs it and won’t work properly without it. It is supposed to be installed by the Avast! installer but I can attest from personal experience that it doesn’t always do it. If it’s not present in the add/remove programs list, download it from Microsoft. First completely uninstall Avast! then install the C++ and then reinstall Avast!. I’m not sure it will fix your problem but I had problems installing Avast! on the Vista machine here and it’s what I had to do to get things working correctly.
