I run Windows XP updated to the latest service pack and updates. I currently use Avast Antivirus, Windows Defender and IObit Advanced Systemcare. I use the Windows Firewall as I had been advised this was sufficient for my needs (after ZoneAlarm caused everything to go slow...) I used to run Webroot antispyware on the recommendation of my PC supplier, but also seemed to cause conflicts and go-slows, as did AVG (which I replaced with Avast).
I have read that IObit is "rogue", although it seems to work fine on my system and seems to do an OK job on cleaning up after me. However, I have read on this forum that SUPERAntiSpyware and Malwarebytes are better software. Should I install these instead? Is it safe to leave IObit in place?
I don't download more than the occasional video clip, don't use P2P sites and mostly just use the PC for email and information surfing. I mostly use Firefox (latest version) with No-Script and WebOfTrust, but we have to occasionally use IE as my work email isn't optimised for Firefox and my wife prefers IE (for some reason).
Advice gratefully received...
