While looking at the Windows MarketPlace/antivirus software site for a new anti-virus program, I discovered and intalled this real-time protection program(not really an AV program, but a supplement to one) called ThreatFire Free along with the AV, PC Tools AntiVirus Free. Now ThreatFire Free looks like a really good program from it's description, however, I already have Geswall installed on my computer, and apparently an older version because last time that I was at this forum, it looked like Geswall may have been on it's way out, but I noticed that it made a comeback. But anyway, yesterday I opened up my SAS progam(apparently, an older version too), and my computer started running very slow and the hard drive kept making a continous revving up sound and I had to restart my computer. Now I don't know if the problem that I was having with my computer was because of the bug that was mentioned in the SAS thread for the older version of SAS, or if perhaps I have too many protection programs on my computer, especially having both Geswall and ThreatFire Free on my computer. Also, I know that installing the new version of SAS will obviously be better for my computer, but I was wondering if anyone had any opinions about having both Geswall and ThreatFire on my computer...not to mention the other protection programs that I have on my computer which also include Spybot and a-squared free. Also, I'm curious about any opinions in regards to the ThreatFire Free program versus the Geswall program. Thanks in advance for your help.
