Running AV programs?

Can I run AVG free, AVG anti-spyware, A2 Squared free and Spyware blaster from my PC? Will they affect each others' performance? My op sys is WinXP with Windows firewall. All above have been downloaded from MG site.
Thanks

 

Yes. AVG free and AVG antispy work well together, and A2 squared does not provide real-time active protection (it only scans and removes malware). And Spyware Blaster is kind of a web site 'blacklist' program, offering a different type of real-time protection. You should experience no conflicts or resource problems. The only thing I can see would be if both AVG's started their auto updates at the same time; that might cause a momentary bog down, but other than that, you're golden!

many thanks for that. I run manual updates with both AVG's anyway.
As always. MG's are the BEST.
Cheers
