404201	2005-11-13 20:32:00	A couple of weeks ago my puter went to a tech under extended warranty to get cd rom replaced, and more ram added, and since it come back, I have had numerous errors, things not working, avg not updating, etc . I took it back, and he reckons that avg lets through viruses, and sure enough, he installed Nod32 and there were trojans . Now, I run a virus check with avg, up to date, the day before I took it to him, and it was clean . As I also run Spy Bot, who he says is useless also . The upshot is that every program I run, or folder I open, the cpu usage goes straight to 100% usage . According to Nod, there are now multiple errors or damaged files in my pc . Has anyone else heard of this sort of coincidence, avg letting through multiple virus' when it is always completetly up to date? And does it mean I am going to have to reformat . I am running a Compaq, XP Home service pack 1, with avg and zone alarm . And of course, with me buying a 'supermarket' puter, as it has been called, it does not come with discs, but I did burn the back ups as soon as I got the pc . Any help greatly appreciated, as I dont' know enough to be able to argue with this guy, but it was going great when it went to his shop, now is going like crap . And wont run heaps of programs without it telling me this or that file is damaged . LIke when I try to instal the latest Spy bot, and msn messenger wont run at all, and it wouldnt' let me update or reinstall avg, etc . Ps to this thread is that the computer guy is being really helpful, but just wanted some heads up from other techs, and if they same it can happen, I will accept that, just seemed weird to me .	supergran (108)

404203	2005-11-13 20:39:00	he installed Nod32 and there were trojans. what trojens where found ? was there anything unusual in the program list in ZA ? as far as other faults go i wonder if they was a problem with the new ram and files/registry got corrupted.	tweak'e (69)

404205	2005-11-13 20:48:00	Thanks Jack, that is what he said . Tweake, without going back to my puter and checking the nod report log, I can't remember what it was, but at first I thought it was the ram conflicting too, but he changed that, and it is still doing the same thing . Thanks and I will check back on my puter, and let you know, but haven't been using it much, as scared of the way the cpu keeps hitting 100% . I dont' want to cook it . But now I see that it is possibly not something he has done, and according to Jack, avg isn't foolproof, I may just have to take his word . It is easy to blame new tech, rather than the puter I guess, but as it is one I hadn't used, I just wasn't happy . Ps, nothing extra found in za, but he did suggest getting sp2 on quickly, and using windows firewall, but with the puter the way it is at present, it is a waste of time trying to put in sp2	supergran (108)

404207	2005-11-13 21:05:00	What may have happened is you had some malicious code that sunk its claws deep into the system files, The tech installed Nod32 which just kills AVG when it comes to detecting nasties, removed the code but left the infected files damagaed. No antivirus program can repair the damage, just remove the filth. Ive seen it happen, Or more rightly, I have done it more then once, Hit the system with the heavy tools and she turns to custard....

404208	2005-11-13 21:09:00	if there was nothing in ZA list then i doubt it was a trojen . its comman to have a AV pick up left overs that other tools (AV, antispyware) have left behind . thats not normally a problem as the leftovers don't actually do anything, it just LOOKS like your infected with something when all it is the AV picking up on a leftover or a cleaned file . as far as " avg letting through multiple virus " go that sounds like the usuall BS . every one has their own favorites and dislike . looks like this person just hates AVG . considering the person advice of "getting sp2 on quickly, and using windows firewall" i would be inclined to keep away from any such tech who recommends windows firewall exspecially when you allready have a better one installed! free AV's are okish on home pc's, a paid pro one is normally better . but at first I thought it was the ram conflicting too, but he changed that, and it is still doing the same thing sometimes a conflicting ram will corupt files/registry and cause all sorts or werid havoc . once its done , it done . changeing the ram won't fix the corupt files . reinstall the OS and programs . BTW whats the specs of the pc? (motherboard exspecially) .	tweak'e (69)
404209	2005-11-13 21:14:00	Ive seen it happen, Or more rightly, I have done it more then once, Hit the system with the heavy tools and she turns to custard.... exactly right. virus's and malware are far better writen these days, you don't notice they are runing on your pc. years ago most spyware or virus made your pc run like crap so it was noticed easly, not any more. very comman for the removal to bust a pc tho most techs would know to fix the pc after a cleanup.	tweak'e (69)
404210	2005-11-13 22:09:00	I wouldn't trust a free A/V program as far as I could kick it. Take the plunge and buy McAffee or Norton A/V SIGH............i HATE repeating myself but as for NORTON............ DONT EVER BUY ITit's RUBBISH stupid statement by our esteemed jjjjj............i have on NUMEROUS occasions used avg to remove trojans from systems which had the most up-to-date versions of norton on the system and norton was saying 'no virus no nasties' .........but avg found them.....and my own viewing of taskmanager showed them..........as METLA says tho: NOD32 is the best bar none ........but that generalisation of jjjjj's..........was just SILLY......and INNACURATE	drcspy (146)
