I’ve had Comodo firewall and antivirus on my personal laptop (XP pro, sp 2) for about a year and am very pleased with it.
The company I work for, however installed AVG on my workstation (XP pro, sp 2, fairly high spec ), which I had no problems with until the latest version which often hung Outlook and had a very irritating “pre-view” feature for websites.
Anyway, I decided to ditch AVG and install Comodo antivirus.
After uninstalling AVG and restarting, I installed the latest version, and restarted (as required). Some of my start-up apps started, but the PC hung and was unresponsive.
I tried restarting a few times, with no further luck - after a few of the start-up apps (SQL Express server, Synergy, etc) started, the PC became unresponsive. I could see the Comodo processes at work in the Task manager, but nothing was eating up a large amount of RAM
I then reverted to an earlier restore point, and restarted as normal.
I decided to try again : uninstalled AVG, restarted, installed Comodo, restarted, and once again my machine hung.
I have had to go back to the system restore point before I installed Comodo for the first time.
Now, the question is this: I have a 250 GB drive, and I do know that Comodo wants to scan the machine at first run. Was I simply being impatient ( I waited more than 1/2 and hour) or is this hanging a more serious thing?
