SpyHunter is set up to run everyday when I turn on my desktop computer. My Desktop runs Windows 5.1. We usually get around 80-100 low level "spy things" that show up and Spy Hunter removes them. Yesterday, after downloading Firefox 4 we got no malware spy hits. Today, we got one, but we got a message that said we had to restart our computer to remove the malware. We restarted and Spy Hunter just wanted to scan again. We stopped the scan. Kaspersky Antivirus is set up on my laptop (running Windows 7). After I downloaded Firefox 4, I get a message that states that Kaspersky Antivirus is not turned on. When I open the Action Center of Kaspersky, I shows that the Anti-virus protection is turned off. The rest (firewall, updates, spyware protection, internet security settings, account control are all still "on"). I find it really strange and somehow connected to the downloading of Firefox 4 since both my desktop and my laptop now have problems with my SpyHunter and Kaspersky. Can I, or should I go back to the earlier version? If so, how do I do that? Thanks! Marbeth Austin
