resident protection advice

Hi again

Not a problem this time - just some advice required please. I have had the hard drive replaced (80GB to 320GB) and 512MB RAM to 1.5GB - mainly due to accommodate photos and music files and to just speed up the computer to cope with the various software etc on it. Have had this done by 'proper' computer people (i.e. not me!) and when re-installing Spybot S&D they had problems with profiles being lost (again!) so we have uninstalled it altogether because it is just not worth the hassle anymore.

Details of what I do have are:

OS Microsoft XP Home
Comodo Internet Security firewall
Avast antivirus
SpywareBlaster

Also have CCleaner, Revo Uninstaller and Startup.exe for 'housekeeping'.

The engineer ran Malwarebytes Anti-Malware and still found infected files on the pc, even with the above protection + Spybot S&D. I realise it is unrealistic to expect 100% protection, but that result to me suggests that perhaps I could have some more.

Do you have any suggestions for further resident protection which is compatible with what I already have, or maybe regular online scans I can do as well, or as an alternative to, further resident protection?

Thanks for your time

 

Have 75% of yours defence:Avast,Comodo AND Malwarebytes Anti-Malware.My daily routine is always when I don't use IE (right click recycle bin and click run CCleaner).If you think that MAYBE you have a virus go with boot scan (with all updates).

 

Thank you - are you able to give a safe link to download Malwarebytes Anti-Malware and, excuse my ignorance, how do I do a boot scan (with all updates) please?

GOOD LUCK!!!!!!!!!
