Presently running IE6 (with latest updates + Avant front end) and Windows Defender, hence security is locked up tight, except for "trusted sites". Agree about AV companies promoting sales by hyping up risks, however my AVG has popped up with virus warning when directed to some sites while researching info & tools for WinPE. Agree some AV progs really slow down the system (or contribute to crashes) so are permanently banned from my systems. No such problem with Grisoft AVG. Agree the atdmt download site is probably safe but how many would be willing to risk it after the bad publicity? I would rather be paranoid and clean, than open and infected! Thanks for link, downloaded and installed IE7 b3, now testing, so far, so good. Hopefully I can now relax some restrictions without the previous risk from malware.
