In the past I have used and been real happy with Avast free,that computer died and I picked up another XP system,it was loaded with the above and I was told by the shop it’s one of the best so that is all I have been using,the first few days it detected a couple of viruses,I have the scan and update set to run every evening,it has detected nothing in about 5 months.
My questions ,If I add Avast is it compatible with Microsoft Security Essentials or should I disable or delete it.
I’m also having some issues with Silverlight/netflix/chrome
Best Victor
Having two resident anti-virus scanners installed is one too many and not recommended as rather than provide twice the protection it can cause conflicts that could leave you more vulnerable.
So yes you should remove MSE before installing avast.
As DavidR said You’ll have to delete MSE before installing Avast, after removing MSE run a search in your system for Microsoft Antimalware and delete remnants.
Personally I don’t even have Silverlight installed as I’ve only ever seen Microsoft sites that require it to view certain things so imo I would uninstall it unless you absolutely need it.
As for netfix or Chrome I use neither so others may be able to help you with them.
Thank you for the replies,should I also delete windows firewall ?
best Victor
No, the Windows firewall plays fine with avast. 
Avast is much better than MSSE. Avast has so many more useable features, it updates every 4 hours instead of once a day like MSSE, Avast has a lot more protection with the different shields and sandbox feature and Avast is easy to customize so you can set it how you need it.
One of the main advantages I see is that MSSE only alerts you after it finds a virus or malware. Avast stops the virus from getting on my computer in the first place. I did a ton of research before installing Avast and MSSE was consistently rated very low in nearly every single AntiVirus review and comparison. I really like how Avast will give me an error window and alert me that it blocked me from accessing a malicious web site.
I do not know about the firewall in XP. I use Windows 7 and also use the built in Windows firewall and it works fine with Avast.

thanks for all the replies and tips,guess i’m going back to Avast
Good to hear
Problem ! successfully down loaded,installed and registered during installation I noticed it did a quick scan with no issues,I tried a full scan and my system shut down to a black screen then reboot,checked a few sites,e-mail, connection speed, all ok tried a couple more times to do a full scan,same issue
Please follow the instructions in this thread http://forum.avast.com/index.php?topic=53253.0 and post all logs back here when completed for one of the malware specialists to look over.
essexboy has been notified.
I see it’s not free,is there any other way to fix this problem I rarely if ever buy anything on line
What’s not free ???, everything within that logs thread link is free
If your talking about Malwarebytes it is free for manual scans and updating which must be performed first before running a scan.
Oh My I’m sorry,I was able to install malwarebytes, ran the quick scan it found three items,and deleted them,I then tried another full Avast scan with same results,straight to reboot. as you can tell I’m no computer expert
I’d suggest for you to run the tools and post the logs so that they can be looked over as there is obviously something wrong within your system that needs investigating.
Just a guess - Is your computer overheating while running the scan?
If Malwarebytes has found and deleted stuff then I’d say the system is infected.
Yoshi,no tower cool to the touch and no unusual noise
Craigb,when say run the tools are you refereeing to additional tools within Malwarebytes Anti malware and post the logs here
,thanks for all your help folks
Yeah, that’s what I thought too, but generally when computers instantly shut down it’s because of overheating.
* Yoshi2889 unfortunately has experience
No don’t use those additional tools in MBAM, run these tools for normal scans as there explained in the link and attach the logs with the " Attachments and other options " below where you write your posts, see pic
