You lose Real-Time Protection, Scheduled Scanning and Automatic Updates; but if money is tight (me) this may be one less expense.
Generally I don't like real time protection anyway. I have been using the free version of SAS for years.
Real-time protection provides a false sense of security. Waste of money IMO. SAS real-time didn't block the FBI hoax. (Avast missed it as well).
Maybe it should be REAL time protection. Relatively Effective Although Lacking
I have told this before. But the only time I ever had a system hosed by malware was an IE BHO. I had 2 desktops with a kvma switch. The other PC was brand new and I was still doing the initialization. Since it was a preload of Vista x64 and I did not have the chance to make recovery disks or a backup image yet, when I could not get the kvma to switch to the PC that was being hosed I just let it happen rather than risk losing the preload on the new PC.
I just wiped the hosed PC and installed XP Pro on it. So far I have never had a rootkit or anything more serious than prankware(opening a zillion windows etc..)
Every time I tried something real time other than straight VSS based stuff, it hampered how my machines ran to an unacceptable level. So I really have no choice. The way I use RollbackRX is similar to ToolWiz Time Freeze. I just use the baseline to back off installs I don't like. Time Freeze is free and is OK but it squeezes the write redirects into a 5 GB file. For some things this is fine but other times you notice a severe performance degradation. But I would likely not put up with all the hassle involved in using RollbackRX if System Restore worked on my Laptop. I have to uninstall RollbackRX to defrag and/or backup with Macrium. Anyway, sorry for hijacking the thread.
