I have used Avast for a number of years now, and infact have it on my other 2 pc’s, however I thought Avast was conflicting with another software a few months ago, and decided to uninstall it, and installed AVG (yes yes I know, how could I?).
I wasn’t happy with AVG, so uninstalled it, rebooted, installed Avast, rebooted , and no matter what I do, I cannot get it to load at startup. It says the resident shield is set to standard, but I have no icons in the taskbar, although in settings the relevant boxes are ticked. I cannot find it in startup in msconfig, security centre doesn’t show it, but in services it does show it, but as Avast3, not 4.
I have run regcure, done malware and adware scans, rebooted, but still no joy.
Can anyone suggest what I should do please? ???
Hi :
BEFORE re-installing Avast, did you run the appropiate AVG Remover Tool
located at www.avg.com/download-tools !?
P.S. What other program did you think Avast was “conflicting” !?
No I didn’t, I just removed it using the Control Panel.
Sounds like you need to run the avast! uninstall tool at http://www.avast.com/eng/avast-uninstall-utility.html too if avast!3 services are showing up. Could be lots of strange stuff in the registry at the moment.
I have clicked on the link you provided, and have run the avg uninstaller tool, so I will uninstall Avast, then reinstall it again and see if that helps.
I just remembered why I uninstalled Avast a few months ago. It wasn’t a conflict, I had 2 trojans which it didn’t detect, and it took my pc ages to sort out because of them. I decided to uninstall it rather than mess about, but that’s backfired a bit hasn’t it!
Thanks for your help, will let you know if it works.
Hi :
To increase your Chances of a successful Avast installation, I recommend
running the Avast Uninstallation Utility, then running the appropiate AVG
Remover Tool, then download Avast . You should use additional program(s) to
“supplement” Avast; the most common Recommendations are the FREE Version
of “SUPERAntiSpyware” from www.superantispyware.com AND the “Free” Version
of “Malwarebytes’ Anti-Malware”, available from
www.malwarebytes.org/mbam.php .
Success! I didn’t get chance to read your last post, as I was already trying to sort it out. Decided to just reboot the pc first without going through all the rigmarole of uninstalling it again, and hey presto, it’s working brilliantly.
Thank you 
Will also check out those other programs as well, as I must admit I have never heard of them.
Thanks again.
