am using avast 4.8 home edition on windows XP still i encounter problems with virus,?

You registered avast and is updated, right? Can you describe the problem? When avast encounters a virus, it locks it up. So what seems to be symptoms of your problem?

Windows XP is a category that Home Edition falls under, just like Office Edition. I assume that if you have a CD for Home, then your OS is Home, but I can't be sure. You could try booting it from the CD but I highly recommend, despite the hassle, that you wipe your hard drive clean through a detailed process and then reinstall the Windows version that the laptop runs on. There are steps to this on the net, but it's a lot easier to use a phone-assistant or a serviceman unless of course you've done it before. I'm not too familiar with the error message, so before you take my advice, I suggest you try an find out whether or not a reboot needs to be taken for such a malfunction. Good luck.

Avast 4,8 home is not very god for those who have direct access to internet, as avast, though an expert in Win32 threats and trogens, is not a very gud option for other viruses.

in my opinion u shud use Bit- Defender, speciality of bit defender over avs is that the virus definitions which bit defender will give u today in its update will be available to u atleast 4 days later in avast.

If u are able to regularly update ur antivirus on an evryday basis then AVG too is a good option.

Do a boot time scan using avast if you still think you have virus,but if it's adware/malware/spyware use malwarebytes antimalware http://www.malwarebytes.org.avast/ is anti virus it protects you against virus attach.

avast 4.8 home edition is a good AV, what makes you think you still have a virus ? Are you sure its not spyware or malware ?

avast is not good all the time.. i had a virus which avast couldn't delete[ wenever i pressed ctrl+alt+del it said task manager has been disabled].. so i removed it and used QUICK HEAL anti virus... it's really good.. u'll know tat for sure once u use it...

You need to back up that product with the two i have on my pc with Avast also....download Malwarebytes anti-malware and also Super anti-spyware...both are free and can be downloaded at CNet.com/downloads............

try Kaspersky ant- virus , it is the best. If u want a free one, try AVG anti-virus.

download norton antivirus 2009 for 90 days trail go link below & download after download scan full system if ur system have any virus it removes it.
