I was having strange things happening to my computer. BSOD frequently with various error messages, loading very slow. I tried a few things I Googled and scanned with 4 different programs. 3 items were found with the highest rated threat level being a 3. Its running much better but I can't open HJT. I've downloaded it from various sites including TrendMicro and Majorgeeks. I get either an 'unexpected error' message or a '50003 error'. These messages also appeared on the HJT I already had which use to work fine. Can anyone help?
