installing MSE could be a huge mistake. my experience with >> on a LEGIT copy of xp pro i installed after i got a nasty malware from a flash add i had my firewall down for 10 mins and this happened, anyway i installed MSE thinking it would take care of t, installed rebooted,
windows just got stuck on log on screen , windows just refused to boot, so booted in safe mode, luckily i had malwarebytes installed updated and cleaned that malware , cleaned the registry entries it had made etc , it was totally gone, booted out of safe mode , windows still refused to boot, well i though maybe that something still remained from that stupid virus soi boooted off from Hiren's BootCD , run the virus scanner from there, all was clean, ran some disk tests everything all ok , by now i was getting bugged as that was the only p.c i had access to on that day , so booted into safe mode again , went into system logs to check what is happening and guess what MSE error : your windows license has expired login denied !!!! and this happened on a legit copy of xp pro i had , anyway windows is so hackable all i had to do was to change the license to a PIRATED, one remove MSE make some changes to registry , and i was good . guess MS likes pirated copies better then legit ones. anyway i would never recommend this to anyone . there is very good chance that you get locked out your system even on legit copies , the risk is too much i knew how to get of that but 70% ppl could get stuck and would be forced to do a reinstall. stick to nod32 and a good software firewall, infact a good hardware firewall combined with a good software firewall like outpost pro and you really don;t need av.
