I have a very disappointing and problematic issue on my Windows 7 64-bit system. I installed Avast long ago, and after 7.0.1456, my system just OS farted. The laptop would boot from the BIOS in 15 seconds, and then I had to endure 20 seconds of a black screen with the cursor, and then the welcome screen (I'd type the password fast) and then, 2 minutes of more black screen, and THEN, more system loading. Overall, 4-6 minutes for full system loading.
I factory reset my laptop 4x this week (4 times due to problems during factory reset, such as a few corrupted files and stuff) and the system I'm currently running (factory reset with all Windows 7 latest updates as well as SP1 installed) and it goes from BIOS to all loaded programs in 60 seconds.
Sure, my start-up programs COULD have had been the cause, hadn't I verified by removing each one of them and leaving Avast Services and Startup program to run. Result was identical, if not worse.
Right now I'm uninstalling Trend Micro Titanium Internet Security 2012 with vendors' uninstall tool to get rid of that unwanted antivirus, but I simply can't go back to Avast if it will slow down my system boot + other system operations constantly.
I'm curious whether a fix will be released soon, or if this is a one in a million issue out there. I sincerely like Avast, and I'm not going to install any other AV soon, but I'd have to refuse to installing Avast if my system will be as slowed down as it had.
To clear, I post this with a honorable respect towards the Avast community, not with any rudeness or bashing towards the program, as I have had no problem with the program on my family's 32-bit laptops. This is just to point out a bug/problem (if it is, I'm not sure. It seriously isn't a defect within my system though) existing within Avast.
My system specifications are below:
Windows 7 64-Bit Home Premium + SP1
Intel Core i7 2630QM Quad Core
Nvidia GeForce GT540M 1GB
6.00GB RAM Memory 1333MHz
640GB HDD - 5'400RPM
